Chinese Overhead & Gantry Crane Manufacturer

Trade statistics can help show the scale of international crane movement between China and African markets. For crane-related trade research, HS 842611 is an important customs classification covering gantry and overhead travelling cranes on fixed supports.

The data can be used to examine:

• China's crane exports to African countries
• African imports of cranes from China
• Import value
• Reported quantity
• China's share of a country's imports
• Main supplying countries
• Changes in import demand over time

Countries such as South Africa, Nigeria, Egypt, Kenya, Morocco, Ghana, Angola, Tanzania and Zambia can be reviewed separately when preparing country-specific market pages.

How to Read Crane Import Data

Trade data should be treated as a market reference, not as a direct count of EOT cranes.

An HS code may cover more than one crane configuration. A reported quantity may also represent customs units rather than a simple count of complete cranes. One large industrial crane can have a very different value from a small workshop crane.

For this reason, a reliable market analysis should compare:

• HS code
• Export or import value
• Reported quantity
• Country of origin
• Destination country
• Year
• Crane type
• Project capacity
• Actual equipment specifications

China-to-Africa Crane Trade

China's crane exports to Africa include complete overhead cranes, gantry cranes and related lifting equipment. African import data can also show where Chinese suppliers compete with manufacturers from Europe, India, Turkey and other crane-producing countries.

For buyers, the trade data provides useful market context. The actual crane specification still needs to be confirmed through a technical RFQ.

A proper EOT crane inquiry should normally include:

• Crane type: Single girder, double girder, gantry, semi-gantry
• Rated capacity: In tons, with any auxiliary hoist capacity
• Span: Distance between runway rails, center to center
• Lifting height: From hook at highest position to lowest position
• Duty class: FEM or ISO classification based on load spectrum and cycles
• Hoisting speed: Main and auxiliary speeds, single/dual speed or VFD
• Travel speeds: Trolley and bridge travel speeds
• Power supply: Voltage, frequency, phase, and type of power feed (cable festoon or conductor bar)
• Control method: Pendant, radio remote, cabin, or combination
• Indoor or outdoor operation: Affects enclosure ratings and corrosion protection
• Ambient conditions: Temperature range, humidity, dust level, corrosive atmosphere
• Existing runway information: Rail size, gauge, length, elevation, and condition
• Required delivery scope: Complete crane, crane kit, or selected components

This information allows a manufacturer such as Yuantai Crane to match the crane structure, hoist, drive system and electrical equipment to the actual working conditions rather than quoting a crane from capacity alone.

The tables below show the typical technical range for Yuantai single girder EOT cranes suitable for African industrial applications. All figures are project-specific and should be confirmed against actual site conditions.

The actual range depends on the crane model and project conditions. For example, a 5 ton workshop crane with an 18 m span and a 9 m lifting height has very different structural and duty requirements from a 20 ton crane working 20 hours per day in a steel service center.

One point that is often overlooked in African projects is the crane wheel load. The total load transmitted to the runway beam includes not only the lifted load but also the dead weight of the bridge and trolley. For a single girder crane, the wheel loads are lower than for a comparable double girder crane, which can be an advantage when the existing runway structure has limited load capacity. This is particularly relevant in older African workshops where the building structure may not have been designed with heavy crane loads in mind. Yuantai provides wheel load data as part of the technical proposal so that the buyer can verify the building structure can support the crane.

Power supply considerations for Africa:

• Most African countries use 50Hz frequency, which is compatible with Yuantai's standard motor range.
• Common voltages: Nigeria (415V), South Africa (380/400V), Kenya (415V), Ghana (400V), Egypt (380V), Morocco (380V).
• Yuantai can accommodate voltage variations of ±10% through appropriate motor and control selection.

To ensure the crane matches your African site requirements, provide the following key data at the inquiry stage. Complete information helps avoid delays and ensures the proposed crane is suitable for local conditions.

• Maximum lifting load: The heaviest single item to be lifted, including any lifting attachments (slings, magnets, spreader bars).
• Span between runway rails: The center-to-center distance between the two runway rails. This determines the bridge length and the structural design of the girder.
• Required lifting height: The vertical distance from the hook at its highest position to the lowest position where the hook must reach.
• Maximum headroom available: The available vertical space from the runway rail to the roof or overhead obstructions. This limits the overall crane height and affects the hoist selection.
• Daily operating hours: The number of hours the crane is expected to be in use each day. This influences the motor duty rating and the hoist group selection.
• Lifting cycles per hour: The number of lifts performed per hour. Combined with the load percentage, this defines the duty class.
• Maximum load percentage: The proportion of lifts that are at or near the rated capacity. A crane that lifts 10 tons 80% of the time requires a higher duty class than one that lifts 10 tons only 10% of the time.
• Power supply: Voltage, frequency, phase and the type of power feed available at the site (cable festoon or conductor bar).
• Control method: Pendant, radio remote or cabin. For single girder cranes, pendant and radio remote are the most common in Africa.
• Indoor or outdoor installation: Outdoor cranes require additional weather protection, corrosion-resistant finishes and wind load calculations.
• Site environmental conditions: Dust levels, humidity, temperature range and any corrosive atmosphere.

For a general African manufacturing workshop, a 5 ton or 10 ton single girder EOT crane is often the first choice. These capacities cover the majority of routine material handling needs in factories and workshops across the continent. Where the load, span or working frequency increases, a double girder design may be more suitable.

Single Girder vs. Double Girder: A Selection Guide for Africa

The choice between a single girder and a double girder crane is not always obvious. Here are some practical guidelines for African buyers:

• Choose single girder when: Capacity is 20 tons or less, span is moderate (up to 28 m), headroom is limited (single girder has lower overall height), and the crane is used for general workshop lifting rather than continuous heavy production. This is suitable for most small and medium-sized African factories and workshops.
• Choose double girder when: Capacity exceeds 20 tons, span is very large, lifting height is high, duty class is heavy (ISO M6+), or the crane needs to handle loads close to capacity on a frequent basis. This is common in mining workshops, steel plants and heavy engineering facilities.
• Cost consideration: A single girder crane typically costs 20–30% less than a comparable double girder crane for the same capacity and span, making it the preferred choice when the duty conditions allow. For African buyers working with limited capital budgets, this is a significant factor.
• Logistics advantage: Single girder cranes are lighter and can be shipped in standard containers, reducing shipping costs and simplifying port clearance in African countries where infrastructure is still developing.

Common Mistakes When Specifying a Single Girder Crane in Africa

Buyers sometimes specify a single girder crane for an application that really needs a double girder design. This can lead to premature wear, frequent breakdowns and safety risks. The most common mistake is specifying the crane based on capacity alone, without considering the duty class. A 10 ton crane used 8 hours per day at near-full load requires a much more robust design than a 10 ton crane used 2 hours per day at half load.

Another common error in African projects is failing to account for the actual lifting height including the hook block and slings. The lifting height specified should be the hook height at the top position, not the clearance to the roof. Yuantai recommends adding at least 500 mm of clearance between the hook block at its highest position and the roof or overhead beams to allow for safe operation and future maintenance.

Finally, many African buyers overlook the power feed arrangement. Single girder cranes typically use a cable festoon system for the trolley power supply. The festoon cable runs along the bridge girder and feeds power to the hoist trolley as it travels. This is cost-effective for most applications but requires proper cable support and tensioning. For high-speed or high-frequency applications, a conductor bar system on the bridge girder may be more reliable.

After-sales support for Africa:

• Yuantai provides technical documentation in English and French to support local installation and maintenance teams.
• Spare parts: Critical wear parts (brake shoes, contactors, limit switches, ropes) can be stocked locally or shipped quickly from Yuantai's warehouse.
• Remote support: For sites with internet connectivity, Yuantai can provide remote technical assistance via video calls and diagnostic support.

The tables below show the typical technical range for Yuantai double girder EOT cranes suitable for African heavy industrial applications. All figures are project-specific and should be confirmed against actual site conditions.

For higher-capacity cranes above 100 tons, an open winch trolley is typically used instead of a standard electric wire rope hoist. This arrangement allows the lifting mechanism to be engineered specifically for higher loads, longer lifting heights and heavier duty cycles. The open winch design uses a separate rope drum and motor, with wire rope reeving arranged for the required load capacity and lifting speed.

One important consideration for African double girder crane projects is the wheel load distribution. Double girder cranes have higher wheel loads than single girder cranes, which means the runway beams and columns must be designed to support these loads. For existing workshops, Yuantai provides detailed wheel load calculations and runway beam reaction data so that the buyer can verify the structural capacity of the building.

A double girder crane can be fitted with multiple hoisting arrangements to suit different operational requirements. This flexibility is one of the key advantages of the double girder design.

Typical configurations:

• Main hoist only: A single hook for the full rated capacity. Suitable for applications where all lifts are heavy.
• Main hoist plus auxiliary hoist: A heavy main hook and a lighter auxiliary hook on the same trolley. The auxiliary hoist is faster and more economical for routine lighter lifts.
• Two independent main hoists: Two heavy hooks for handling long or unbalanced loads, such as steel beams or transformer tanks.
• Main and auxiliary hooks with independent lifting mechanisms: Each hoist has its own motor, gearbox and control, allowing simultaneous or independent operation.

Typical capacity combinations for African projects:

• 50T main + 10T auxiliary: Common in mining maintenance workshops
• 100T main + 20T auxiliary: Typical for steel mills and heavy fabrication shops
• 160T main + 32T auxiliary: Used in power plants for turbine and generator maintenance
• 250T main + 50T auxiliary: Found in large mining plants and heavy engineering facilities

For example, a crane may use a 50 ton main hoist plus a 10 ton auxiliary hoist. The main hook handles heavy equipment such as gearboxes, crushers and motors, while the auxiliary hook handles smaller components during maintenance, reducing energy consumption and improving speed for lighter lifts.

Benefits of auxiliary hoist in African operations:

• Energy savings: The smaller auxiliary hoist consumes less power for routine lighter lifts.
• Faster operation: Auxiliary hoist speeds are typically higher than main hoist speeds, improving productivity for small lifts.
• Reduced wear: The main hoist is used only for heavy lifts, extending its service life.
• Operational flexibility: Two hooks allow handling of unbalanced or multiple loads simultaneously.

For African mining, steel, cement and power projects, the design should carefully consider the following factors to ensure the crane meets operational requirements and has a long service life.

Key Technical Parameters

• Maximum wheel load: Must be checked against runway beam capacity.
• Crane span: Center-to-center distance between runway rails.
• Runway beam capacity: Existing or proposed beams must support wheel loads.
• Building column spacing: Affects runway beam length and support.
• Available headroom: Distance from rail to roof limits crane height.
• Hook approach distance: Minimum distance from hook to wall.
• Lifting height: Vertical hook travel from top to bottom position.
• Load spectrum: Distribution of loads lifted over time.
• Daily operating hours: Affects motor duty and thermal ratings.
• Start/stop frequency: Affects contactor and VFD selection.
• Outdoor wind conditions: For outdoor installations, design for specified wind loads.

Environmental Factors in African Installations

• Temperature: High-temperature options with Class H insulation for 45°C+ conditions.
• Dust and grit: IP55 or IP65 enclosures recommended for mining, cement and steel.
• Corrosion: Hot-dip galvanized components and epoxy paint for coastal installations.
• Altitude: Motor derating required for altitudes above 1000 m.

Power Supply Considerations

• Voltage fluctuations of ±10% or more — Yuantai specifies motors with wide tolerance.
• Harmonic distortion — VFD systems include line reactors and filters.
• Standby power compatibility for critical applications.
• Conductor bar systems preferred for high-duty applications.

Safety and Compliance

• Overload limiter: Standard on every Yuantai double girder crane.
• Load-moment protection: For large-span cranes to prevent overturning.
• Anti-collision systems: Radar or laser-based for multiple cranes on same runway.
• Documentation: Operation manuals, drawings, schematics and CE certification.

A Yuantai EOT crane electrical package can include the following components, all selected to match the site power supply and duty requirements.

For example, a 20 ton double girder EOT crane may use separate motors for hoisting, trolley travel and bridge travel, with VFDs applied where precise movement is required. The exact motor power and speed are calculated from the load, lifting height, duty class and required cycle time.

Africa-specific electrical considerations:

• Phase failure protection: Yuantai includes phase-failure relays that shut down the crane if a phase is lost, preventing motor burnout.
• Under-voltage protection: Circuit breakers with under-voltage trip to protect motors during brownouts.
• Surge protection: Available for regions with lightning risk, protecting VFDs and sensitive electronics.
• Harmonic filtering: Line reactors and filters for VFD systems where power quality is poor.

VFD (Variable Frequency Drive) control is particularly useful for cranes handling heavy machinery, steel products and mining equipment across African industries. It offers significant operational and maintenance advantages over traditional contactor control.

Key benefits of VFD control for African crane applications:

• Adjustable hoisting speed: Operator can select slow speeds for precision positioning and faster speeds for routine lifts, improving productivity.
• Controlled acceleration: Smooth start-up reduces mechanical shock on the gearbox, wire rope and crane structure, extending component life.
• Controlled braking: Regenerative or dynamic braking reduces wear on mechanical brakes, lowering maintenance costs.
• Reduced mechanical shock: Eliminates the "jerk" associated with contactor switching, protecting both the crane and the load.
• Smoother crane travel: Improved ride quality and less load swing during bridge and trolley travel.
• Better load positioning: Precise speed control allows accurate placement of heavy components during installation and maintenance.
• Reduced load swing: Smooth acceleration and deceleration minimize pendulum effect, improving safety.
• Energy savings: VFDs optimize motor efficiency, reducing power consumption compared to fixed-speed contactor control.

Typical applications in Africa where VFD is recommended:

• Mining maintenance cranes: Slow-speed operation helps the operator align a gearbox, motor or pump with its foundation during installation.
• Steel mills: Precision positioning of coils, slabs and billets during production and handling.
• Power plants: Accurate placement of turbine components and generators during maintenance.
• Cement plants: Controlled lifting of kiln sections, crusher components and heavy machinery.

VFD considerations for African installations:

• Harmonic distortion: VFDs can generate harmonics that affect other equipment on the same supply. Yuantai includes line reactors and EMC filters to mitigate harmonic effects.
• Power quality: For sites with unstable power, VFDs with under-voltage ride-through and auto-restart functions are recommended.
• Ambient temperature: VFDs are rated for specific ambient temperatures. For high-temperature African environments, Yuantai supplies VFDs with derated capacity or forced ventilation.
• Enclosure protection: VFD enclosures should match the site conditions — IP55 or IP65 for dusty or wet environments.

For a mining maintenance crane, for example, slow-speed operation can help the operator align a gearbox or motor with its foundation during installation. For a steel mill crane, VFD control allows smooth acceleration and deceleration when handling coils, reducing the risk of load swing and improving safety.

For steel mills, foundries and cement plants in hot African climates, the specification should state the actual ambient temperature at the crane location. Many African regions experience ambient temperatures above 40°C, and cranes near furnaces or hot products can be exposed to even higher temperatures.

Typical checks for high-temperature applications:

• Motor temperature rise: Motors should be rated for the actual ambient temperature, with appropriate temperature rise limits
• Class F insulation: Standard for motors in hot environments; Class H recommended for extreme conditions above 45°C
• VFD temperature limits: VFDs must be derated for high ambient temperatures; forced ventilation or air conditioning may be required
• Brake temperature rating: Brake coils and friction materials must be rated for the operating temperature
• Control-panel ventilation: Control panels in hot areas require adequate ventilation or cooling to prevent component overheating
• Electrical component derating: All electrical components should be derated according to the actual ambient temperature

If the crane works close to hot production equipment, the actual temperature at the crane location should be provided rather than using the general outdoor temperature. A crane installed 10 meters above a furnace may experience very different temperatures from one installed 5 meters away.

Temperature ranges for African regions:

• Coastal West Africa (Nigeria, Ghana): 25–40°C with high humidity
• East Africa (Kenya, Tanzania): 15–35°C at moderate altitudes
• Southern Africa (South Africa, Zambia): 5–40°C depending on season
• North Africa (Egypt, Morocco): 10–45°C, extreme in desert areas
• Sahel region (Mali, Niger, Sudan): 20–50°C with high dust levels

Outdoor cranes in African ports, mining sites, steel yards and construction areas require additional consideration for weather conditions. These factors affect both the structural design and the electrical equipment.

Key considerations for outdoor cranes:

• Working wind speed: The maximum wind speed at which the crane can operate safely (typically 20–30 m/s)
• Non-working wind speed: The maximum wind speed the crane must survive when parked (typically 50–60 m/s)
• Rain: Weatherproof enclosures for electrical equipment, sealed cable glands, and drainage provisions
• Solar exposure: Control panels and electrical components may need sunshields or forced ventilation
• Corrosion: Appropriate paint system and corrosion-resistant materials
• Rail conditions: Rails may be exposed to weather; rail sweeps and debris clearance required
• Storm parking: Designated parking position and anchoring points
• Rail clamps: Mechanical or hydraulic rail clamps to secure the crane during high winds
• Wheel and brake protection: Enclosures to protect wheels and brakes from rain and debris

Large outdoor gantry cranes should be checked for wind loads, wheel loads and anchoring requirements during structural design. Yuantai performs wind load calculations according to international standards and provides anchoring specifications for each project.

Outdoor crane types commonly used in Africa:

• Gantry cranes: Used in ports, steel yards, and construction sites — require full weather protection
• Semi-gantry cranes: One rail on wall, one on ground — used in open-sided workshops
• Outdoor overhead cranes: Often found in steel plants and mining facilities with open bays

For South African, Egyptian, Nigerian and other coastal industrial sites, salt and humidity can accelerate corrosion significantly. Ports and coastal facilities require special attention to material selection and surface protection.

Protection measures for coastal installations:

• Anti-corrosion paint system: Marine-grade coating with appropriate primer, intermediate and topcoat layers
• Surface preparation: Sandblasting to Sa 2.5 minimum to ensure paint adhesion
• Protected electrical cabinets: IP55 or IP65 enclosures with sealed entries and gaskets
• Sealed cable glands: Compression-type glands to prevent moisture ingress
• Corrosion-resistant components: Stainless steel or galvanized hardware, fasteners and small components
• Regular inspection points: Accessible areas for corrosion inspection and touch-up painting

The coating system should be selected according to the site's atmospheric corrosion conditions rather than using the same paint specification for every project. Yuantai uses the ISO 12944 classification system for coating selection:

• C2 (low corrosivity): Indoor, low humidity — standard industrial coating
• C3 (medium corrosivity): Indoor with occasional condensation or outdoor in temperate climates — enhanced coating
• C4 (high corrosivity): Outdoor in industrial areas or coastal areas with low salinity — heavy-duty coating system
• C5 (very high corrosivity): Coastal areas with high salinity or industrial areas with high pollution — marine-grade coating system

Key African coastal locations requiring corrosion protection:

• South Africa: Durban, Cape Town, Port Elizabeth
• Nigeria: Lagos, Port Harcourt, Onne
• Egypt: Alexandria, Port Said, Suez
• Kenya: Mombasa
• Tanzania: Dar es Salaam
• Ghana: Tema, Takoradi
• Morocco: Casablanca, Tangier

For a reliable quotation, African buyers should send the Chinese crane manufacturer the following information. Complete data helps Yuantai engineers select the motors, VFDs, control panel, protection devices and electrical enclosures correctly before manufacturing.

This information gives Yuantai engineers enough data to select the motors, VFDs, control panel, protection devices and electrical enclosures correctly before manufacturing. Providing complete data at the RFQ stage avoids delays and ensures the crane is suitable for the actual site conditions.

Additional data for existing workshop installations:

• Runway rail size and condition
• Building column spacing and clearance
• Existing power feed location and type
• Photos of the installation area
• Structural drawings or building layout

South African customs data provides a useful reference for the Chinese crane supply market. Under HS 842611, which covers gantry and overhead travelling cranes on fixed supports, South Africa imported about US$4.22 million of equipment in 2024, with 1,471 reported items. China supplied about US$1.30 million, with 544 reported items.

This means China accounted for roughly 31% of the reported import value and 37% of the reported quantity under this HS code in South Africa in 2024. The figures show that Chinese suppliers already have a measurable position in the South African overhead and gantry crane market.

At the same time, the customs quantity should be read carefully. HS 842611 is a trade classification, not a technical classification for a specific EOT crane model. A reported "item" does not tell us whether the equipment was a 5 ton workshop crane, a 50 ton double girder crane or another configuration.

China's overall exports under HS 842611 were about US$406.17 million and 9,513 reported items in 2024. South Africa was one of the destinations for Chinese crane exports, with the country receiving about US$1.30 million under this category.

Trade data insights for buyers:

• Chinese suppliers are well-established in the South African market.
• Competition includes suppliers from Europe, India and Turkey.
• Trade data should be used as a market indicator, not a direct equipment count.
• For accurate pricing, technical RFQs are more reliable than customs averages.

Chinese manufacturers can configure EOT cranes according to the requirements of South African industrial sites. The table below shows typical specifications for the South African market.

South Africa-specific power supply:

• Common voltages: 380V or 400V, 50Hz, 3-phase
• Some industrial sites use 415V — confirm site supply before ordering
• Yuantai can accommodate voltage variations of ±10%

South African crane projects cover mining, steel production, engineering workshops and equipment maintenance. The crane specification should match the load, duty cycle, runway and site environment rather than capacity alone.

Mining & Mineral Processing Cranes

Mining maintenance cranes may handle:

• Crusher components
• Mill components
• Gearboxes and motors
• Pumps
• Conveyor drives
• Screens
• Heavy maintenance parts

For these applications, Yuantai engineers should calculate the duty from:

• Daily operating hours
• Lifting cycles
• Average and maximum load
• Load spectrum
• Required service life

Typical Mining Crane Configuration

For heavier maintenance work, main and auxiliary hoists, open winch trolleys and VFD control can be specified.

Mining sites should also consider dust protection for motors, control panels, limit switches and electrical connections. The required IP rating should be selected according to the actual installation area.

Steel & Heavy Engineering Plants

Steel fabrication and heavy engineering plants may use EOT cranes for both production and maintenance.

Typical configurations include:

• 5–20 ton single girder EOT cranes for workshop lifting
• 20–100 ton double girder EOT cranes for heavy machinery
• Higher-capacity cranes for large production equipment
• VFD control for precise movement
• Radio remote or cabin control
• Main and auxiliary hoists where required
• Higher ISO/FEM duty classes for frequent operation

For steel coils, fabricated structures and machinery, the RFQ should specify hook height, span, maximum load, lifting cycle and required positioning accuracy.

EOT Crane Kits for Local Fabrication

Where a local contractor has suitable steel fabrication and installation capability, Yuantai can supply an EOT crane kit.

A typical kit may include:

• Electric wire rope hoist or open winch trolley
• End carriages with wheels
• Travel motors and gearboxes
• Control panel with VFDs
• Festoon system and power feed components
• Limit switches and overload limiter
• Radio remote control or pendant
• Technical drawings and assembly instructions

The local fabricator can manufacture the main girder, platforms and selected structural parts according to the approved drawings.

Important dimensions such as wheelbase, runway gauge, girder connection and hoist mounting position should be controlled by the crane design to ensure the locally fabricated structure matches the imported components.

Replacement Hoists & Crane Components

South African plants with existing overhead cranes may not need a complete replacement crane. A new hoist or travelling mechanism can often be supplied if the existing structure remains suitable.

For a replacement hoist, provide:

• Existing capacity and lifting height
• Hoist dimensions and trolley wheelbase
• Power supply details
• Crane nameplate data and photographs
• Existing bridge and runway condition

For mining projects, add the load spectrum, lifting frequency, maximum component weight and shutdown maintenance cycle.

For Chinese crane suppliers, this information turns an RFQ from a simple "20 ton crane price" request into an engineering specification. It allows the main girder, hoist, motors, wheels, electrical system and safety equipment to be selected for the actual South African site.

Note on trade data: HS 842611 is useful for tracking international trade in gantry and overhead travelling cranes on fixed supports. It should not be treated as a direct count of EOT cranes. Customs records can cover different crane configurations and reporting methods, so trade figures are best used as market indicators rather than individual crane model data.

China is an established supplier of industrial cranes and material handling equipment to the Nigerian market.

For trade analysis, HS 842611 is commonly used for gantry and overhead travelling cranes on fixed supports. It provides a useful indication of crane trade between China and Nigeria.

Trade data highlights (2024):

• Nigeria imported approximately US$11.18 million of products under HS 842611
• China supplied approximately US$1.77 million of this import value
• Chinese exports to Nigeria under the same HS code were approximately US$1.47 million, covering about 101 reported items

The data shows an existing supply flow of Chinese overhead and gantry cranes into Nigeria. For buyers, the more useful question is the technical specification of the crane required for the project.

Trade data insights for buyers:

• Nigerian import values show significant demand for lifting equipment.
• Chinese suppliers are well-established but face competition from European, Indian and Turkish suppliers.
• Technical RFQs are essential for accurate pricing — customs data alone does not specify crane configuration.
• Port clearance and logistics should be considered when planning delivery to Nigeria.

Chinese manufacturers can configure EOT cranes according to the Nigerian plant, workshop or industrial yard. The table below shows typical specifications for the Nigerian market.

These are typical engineering ranges. The final crane specification should be calculated from the actual load, building and operating conditions.

Nigeria-specific power supply:

• Common voltage: 415V, 50Hz, 3-phase
• Some sites use 380V or 400V — confirm site supply before ordering
• Voltage fluctuations are common — Yuantai supplies motors with ±10% tolerance
• Under-voltage and phase-failure protection are recommended

Nigerian cement plants often use overhead cranes for planned maintenance and heavy equipment replacement. Crushers, mills, kilns, gearboxes and motors can require regular lifting during shutdowns. The crane should be selected from the actual load and maintenance cycle.

Typical lifting work in cement plants:

• Crusher maintenance
• Kiln maintenance
• Cement mill maintenance
• Gearbox replacement
• Motor replacement
• Pump maintenance
• Conveyor maintenance
• Heavy component installation

Typical Technical Data for Cement Plant Cranes

A double girder EOT crane is generally considered for heavier maintenance loads, larger spans, higher duty cycles or applications requiring greater structural capacity.

Dust Protection for Cement Plants

Cement dust can affect motors, control panels and electrical equipment. The specification should consider:

• Motor IP rating — IP55 or higher recommended
• Control-panel enclosure — IP55 with sealed cable entries
• VFD cabinet protection — filtered ventilation or sealed
• Cable and festoon protection — sealed connectors and dust boots
• Limit-switch protection — proximity switches with sealed housings
• Sealed electrical connections throughout
• Maintenance access for regular cleaning

The final protection level should be selected according to the actual plant location.

EOT Cranes for Nigerian Steel & Machinery Plants

Steel fabricators and construction-equipment manufacturers use overhead cranes for fabrication, assembly, maintenance and material handling.

Typical loads include:

• Steel plates
• Structural beams
• Fabricated steel structures
• Excavator components
• Construction machinery
• Motors and gearboxes
• Hydraulic equipment

A 5–20 ton single girder EOT crane can suit many general workshops. Heavier production and machinery-handling areas may require 20–100 ton or higher double girder EOT cranes.

Where loads are handled mainly in outdoor yards, a gantry crane can avoid the need for a building-supported runway.

Gantry Cranes for Nigerian Industrial Yards

Gantry cranes are useful for outdoor handling where there is no suitable overhead runway.

Typical applications include:

• Steel storage yards
• Construction equipment yards
• Machinery assembly
• Precast concrete handling
• Port maintenance
• Heavy equipment storage

Typical configurations include:

• Single girder gantry crane
• Double girder gantry crane
• Electric wire rope hoist or open winch trolley
• Radio remote control or operator cabin
• Rail-mounted travel

Typical capacities can range from 5–50 ton for general yard handling, while heavier industrial gantry cranes can be engineered for 100 ton, 200 ton or higher loads.

Outdoor cranes should be checked for wind load, rain, humidity, corrosion, rail alignment and foundation conditions.

Power Supply for Nigerian EOT Cranes

The site power supply should be confirmed before crane production. Common configurations include 380V/50Hz/3Ph, 400V/50Hz/3Ph and 415V/50Hz/3Ph, with other project-specific options available.

The selected voltage and frequency affect the hoist motors, travel motors, control transformer, VFDs, control panel, circuit breakers and protection devices. For replacement cranes or hoists, the existing motor nameplate and actual site voltage should be checked to avoid electrical mismatch during installation.

EOT Crane Kits for Local Assembly in Nigeria

A crane kit can suit Nigerian engineering companies with steel fabrication, welding, installation and maintenance capabilities.

The Chinese supplier can provide:

• Electric wire rope hoist or open winch trolley
• End carriages with crane wheels
• Travel motors and gearboxes
• Control panel with VFDs
• Festoon system and power feed components
• Limit switches and overload limiter
• Radio remote control or pendant
• Technical drawings and assembly instructions

The local fabricator can manufacture the bridge girder according to the approved structural design.

Before fabrication, the Chinese supplier and Nigerian fabricator should confirm:

• Steel grade and material specifications
• Girder dimensions and structural calculations
• Welding requirements and quality standards
• Wheel loads and allowable deflection
• Assembly tolerances and connection details
• Electrical installation details
• Responsibilities for testing and commissioning

For the imported components to fit correctly, dimensions such as wheelbase, runway gauge, girder connection and hoist mounting position should be controlled by the approved drawings.

Replacement Hoists & Crane Components in Nigeria

Many Nigerian factories already operate overhead cranes. A complete crane replacement may not be necessary when the existing bridge and runway remain suitable.

Chinese suppliers can provide:

• Electric wire rope hoists
• Hoist and travel motors
• Gearboxes and crane wheels
• Brakes and end carriages
• VFDs and control panels
• Limit switches and festoon systems
• Radio remote controls and overload limiters

For a replacement hoist, provide:

• Crane capacity and lifting height
• Hoist dimensions and trolley wheelbase
• Motor data (power, speed, voltage)
• Voltage and frequency at site
• Duty class and operating conditions
• Existing nameplate and photos
• Available crane drawings

For larger replacements, the existing bridge girder, runway and wheel loads should also be checked before selecting the new hoist.

Documentation for larger projects:

• General arrangement drawings
• Load calculations and wheel loads
• Motor specifications and electrical diagrams
• Spare parts list
• Operation and maintenance manuals

This information allows the Chinese manufacturer to design the EOT crane around the actual Nigerian site rather than supplying a standard crane based only on lifting capacity.

For trade analysis, HS 842611 is commonly used for gantry and overhead travelling cranes on fixed supports.

Trade data highlights (2024):

• Egypt imported approximately US$6.45 million of products under HS 842611
• China supplied approximately US$1.08 million of this import value
• China's reported exports to Egypt under the same HS code were approximately US$1.04 million, covering about 56 reported items

The import and export figures can differ because of customs reporting practices, shipment dates, valuation methods and differences between exporter and importer declarations.

The HS code should therefore be used as a market and trade indicator. It does not identify whether an individual shipment contains a single girder EOT crane, double girder EOT crane, gantry crane or another type of overhead travelling equipment.

For buyers, the technical specification remains more important than the trade classification.

Trade data insights for buyers:

• Egyptian import values show consistent demand for lifting equipment.
• Chinese suppliers have a measurable share of the market.
• Competition includes European, Indian and Turkish suppliers.
• Technical RFQs are essential for accurate pricing — customs data alone does not specify crane configuration.

Chinese manufacturers can configure overhead bridge cranes for Egyptian factories according to the load, building structure and operating environment. The table below shows typical specifications for the Egyptian market.

The final specification should be based on the actual Egyptian project rather than selecting equipment from capacity alone.

Egyptian cement plants use cranes for production equipment handling and scheduled maintenance. Typical lifting work includes crusher maintenance, kiln equipment maintenance, cement mill maintenance, gearbox replacement, motor handling, pump replacement, conveyor maintenance and heavy component installation.

For heavy maintenance loads, a double girder EOT crane can be configured with an electric wire rope hoist or open winch trolley. Main and auxiliary hoists may be used where large equipment must be lifted and positioned during plant shutdowns.

Typical cement plant crane configuration:

• Capacity: 10–100 ton+, project-specific
• Crane type: Double girder EOT for heavy maintenance
• Duty class: ISO M5–M7 / FEM 3m–5m based on shutdown cycle
• Hoist: Open winch trolley with main and auxiliary hoists
• Control: Radio remote or cabin for precision positioning
• Speed control: VFD on hoist and travel motions
• Motor protection: IP55 minimum for dust protection

Dust protection for cement plants:

Cement dust can affect motors and electrical equipment. The crane specification should consider:

• Hoist motors and travel motors — IP55 or higher
• Control panels — IP55 with sealed cable entries
• VFD cabinets — filtered ventilation or sealed with heat exchangers
• Electrical enclosures — fully sealed
• Limit switches — sealed proximity switches
• Cable systems — sealed connectors and dust boots

The required IP rating should be selected according to the actual installation location.

Steel plants and metal-processing facilities use overhead cranes for production, fabrication, coil handling and maintenance.

Typical loads include:

• Steel plates and structural steel
• Fabricated components
• Steel coils
• Motors and gearboxes
• Production machinery
• Maintenance equipment

For general workshops, a 5–20 ton single girder EOT crane can be suitable. Heavier production and maintenance areas may use 20–100 ton or higher double girder EOT cranes with trolley-mounted wire rope hoists or open winch trolleys.

Where accurate load positioning is required, VFDs can be applied to the hoisting, cross-travel and long-travel mechanisms.

Heat considerations for steel plants:

• Motors may require Class H insulation for high ambient temperatures
• Control panels may need forced ventilation or air conditioning
• VFDs should be derated for temperatures above 40°C
• Brakes and friction materials should be rated for the operating temperature

Gantry Cranes for Egyptian Outdoor Yards

Gantry cranes are useful where heavy loads must be handled outdoors and there is no suitable building-supported runway.

Typical applications include:

• Steel storage yards
• Construction equipment yards
• Machinery assembly
• Precast concrete handling
• Port maintenance
• Heavy equipment handling

Typical configurations include:

• Single girder or double girder gantry crane
• Electric wire rope hoist or open winch trolley
• Radio remote control or operator cabin
• Rail-mounted travel

Typical capacities can range from 5–50 ton for general yard handling, while larger industrial gantry cranes can be engineered for 100 ton, 200 ton or higher loads.

Outdoor crane checks:

• Wind load — working and non-working wind speeds
• Dust and sand protection — sealed components
• Temperature — motor and VFD derating for high temperatures
• Rain — weatherproof enclosures and drainage
• Corrosion — appropriate paint system and materials
• Rail alignment and foundation conditions

Temperature and Dust Requirements in Egypt

Egyptian industrial sites can experience high temperatures, especially in outdoor yards and poorly ventilated production areas. The crane specification should confirm:

• Design ambient temperature
• Motor insulation class (Class F standard, Class H for high-temperature)
• Motor IP rating (IP55 recommended for dusty environments)
• Electrical enclosure protection
• Control-panel ventilation
• VFD temperature limits and derating
• Brake operating conditions

For cement plants, dust protection should be matched to the actual plant area. A crane installed inside a protected electrical room will have different requirements from one operating directly beside a crusher or cement mill.

Power Supply for Egyptian EOT Cranes

The electrical configuration should be confirmed before manufacturing. Common options include:

• 380V/50Hz/3Ph (most common in Egypt)
• 400V/50Hz/3Ph (some industrial sites)
• 415V/50Hz/3Ph (project-specific)
• 440V/60Hz/3Ph or other project-specific supplies available where required

The selected power supply affects the hoist motor, crane travel motors, control transformer, VFDs, control panel and electrical protection devices. For replacement equipment, the existing crane nameplate and actual site voltage should be checked before selecting the new motor and control system to avoid voltage, frequency or control-system mismatches.

Data to Provide for Egyptian Crane Projects

For Egyptian crane projects, buyers should provide:

• Maximum load (including lifting attachments)
• Span between runway rails
• Required lifting height
• ISO/FEM duty class
• Daily operating hours and lifting cycles
• Power supply voltage and frequency
• Indoor or outdoor operation
• Ambient temperature range
• Dust conditions (cement, sand, etc.)
• Coastal exposure (if applicable)

This gives the manufacturer enough information to select the hoist, motors, electrical protection and structural configuration correctly.

Morocco

Morocco's automotive, steel, machinery and port industries require cranes for production and maintenance.

Typical loads include steel components, fabricated structures, motors, gearboxes and production machinery.

Typical crane data:

• Workshop EOT: 3–20 ton
• Double girder EOT: 20–80 ton+
• Span: 8–30 m, project-specific
• Hoisting height: 6–20 m+
• VFD available for hoisting and travel
• Control: Radio remote / pendant / cabin
• Gantry crane: 10–100 ton, depending on yard requirements

Algeria

Algeria has industrial demand from oil and gas, steel, cement, manufacturing and heavy engineering.

Typical requirements include:

• Heavy-duty EOT: 20–100 ton+
• Double girder EOT
• Gantry cranes: 10–100 ton+
• Open winch trolley
• Main and auxiliary hoists
• VFD travel control
• ISO/FEM higher-duty classifications

For large plant maintenance, the crane capacity should be based on the heaviest component that must be removed, transported and installed.

Ghana

Ghana's mining, cement, steel and port industries create demand for heavy maintenance cranes.

Typical work includes crusher maintenance, mining equipment handling, machinery assembly and port equipment maintenance.

For larger mining facilities, typical configurations include 20–100 ton+ double girder EOT cranes, with wire rope hoists or open winch trolleys. Main and auxiliary hoists can be used where large equipment must be lifted and positioned during maintenance.

Côte d'Ivoire and Senegal

Cement, ports, construction, manufacturing and logistics are common application areas.

• For general workshops: 1–20 ton EOT cranes
• Larger industrial facilities: 20–80 ton+ double girder EOT cranes
• Outdoor yards: 10–50 ton gantry cranes

Zambia

Mining is a major application for industrial lifting equipment in Zambia. Cranes may handle gearboxes, motors, crusher components, conveyor equipment and other maintenance loads.

• Large mining facilities: 20–100 ton+ double girder EOT cranes
• Open winch trolleys, auxiliary hoists and VFD travel control for heavier maintenance work
• Crane kits suitable where local engineering companies can fabricate the bridge structure and complete installation

Angola

Angola's oil and gas support, ports, mining, construction and heavy equipment sectors require both workshop and yard cranes.

Typical configurations include:

• Workshop EOT: 5–30 ton
• Heavy-duty double girder: 20–100 ton+
• Outdoor gantry: 10–100 ton+
• Wire rope hoist / open winch
• Radio remote or cabin control

Outdoor designs should consider wind, rain, humidity, corrosion and foundation conditions.

Mozambique

Mozambique has potential demand from mining, ports, energy, construction and manufacturing.

Typical crane configurations include:

• Workshop EOT: 5–30 ton
• Double girder EOT: 20–100 ton+
• Rail-mounted gantry: 10–100 ton+
• Electric wire rope hoist
• Heavy-duty crane kits

Outdoor projects should account for wind, rain, humidity, coastal corrosion and ground-rail conditions.

Across these markets, buyers should provide the following basic crane data. All figures are typical engineering ranges, not fixed country standards.

The final crane should be designed from the actual load, span, lifting height, duty cycle, site power supply and environmental conditions.

Crane Selection by Application

Rather than selecting the same crane package for every country, the equipment can be matched to the application.

The capacity ranges are reference values rather than fixed country standards. The final crane should be selected from the maximum load, lifting height, span, duty class, working cycle, power supply and site conditions.

African crane projects vary by industry, plant size and lifting requirements. A mining company may need a high-duty double girder EOT crane, while a manufacturing workshop may only need a 5 ton or 10 ton single girder crane. Outdoor equipment yards may be better served by a gantry crane.

For Yuantai Crane, the market can be organized by industrial application and crane requirement rather than presenting the same product list for every country. This makes it easier for buyers to identify the equipment that fits their project.

The table provides a starting point for matching the crane type to each market. The actual selection still depends on the lifting capacity, span, lifting height, duty class, operating cycle and site conditions.

For example, mining projects in South Africa and Zambia may require higher-duty double girder EOT cranes for motors, gearboxes, crushers and other heavy equipment. Cement plants in Nigeria and Egypt may require overhead cranes for kiln, mill and crusher maintenance. Manufacturing projects in Kenya, Morocco and Ethiopia may have more demand for single girder EOT cranes and workshop lifting systems.

Yuantai can also supply different levels of equipment according to the customer's project model. A complete crane can be supplied for a turnkey installation, while crane kits, electric wire rope hoists and replacement components can be supplied to engineering companies that carry out local fabrication or maintenance.

Each country section can then link to the relevant EOT crane, single girder crane, double girder crane, gantry crane, crane kit or electric wire rope hoist page. This avoids repeating technical specifications while giving buyers a direct route to the crane information relevant to their application.

China's crane exports can be compared across major African markets. The table below shows the main industrial demand and typical Chinese crane supply for each market.

The data can also be extended to Mozambique, Ethiopia, Côte d'Ivoire, Senegal, Uganda, Zimbabwe and Namibia when evaluating specific projects.

Key insights from the data:

• Chinese suppliers have a measurable presence in all major African industrial markets
• South Africa, Nigeria and Egypt represent the largest import volumes
• East African markets (Kenya, Tanzania, Ethiopia) show growing demand
• West African markets (Ghana, Côte d'Ivoire, Senegal) are developing
• Southern African markets (Zambia, Angola, Mozambique) are driven by mining and port activity

The trade flow shows that Chinese lifting equipment is already entering a range of African industrial markets. This supports several supply models for African buyers.

Available supply models from China:

• Complete EOT crane systems for new factories and plant expansions
• Double girder cranes for heavy industrial applications (mining, steel, cement)
• Gantry cranes for outdoor yards and port areas
• Crane kits for local fabrication and assembly by African engineering companies
• Electric wire rope hoists for new or existing cranes
• Replacement components for crane maintenance, modernization and upgrades

How to use trade data effectively:

• Use import figures to identify which countries are actively buying cranes
• Use year-on-year changes to track market trends
• Use China's market share to understand supplier competition
• Do not rely on trade data for technical specifications or pricing

For buyers, import statistics are best used to understand supplier availability and market activity. Final crane selection still depends on the project specification: capacity, span, lifting height, duty class, operating cycle, power supply and site conditions.

Country-Specific Trade Data Summary

The table below summarizes the 2024 trade data for key African markets under HS 842611.

Note on data interpretation:

• Import and export figures may differ due to customs reporting practices, shipment dates and valuation methods.
• HS 842611 covers multiple crane types — market share percentages are indicative, not exact.
• For accurate project planning, always use technical RFQs rather than trade averages.
• Yuantai can provide updated trade data and market analysis for specific countries on request.

Duty class should match the actual lifting cycle. A crane used 8 hours per day at near-full load requires a much higher duty class than one used 2 hours per day at half load. Provide the following data to allow correct selection.

Data required for duty class selection:

• ISO / FEM classification — e.g., ISO M5 or FEM 3m
• Daily operating hours — hours per day the crane is in use
• Lifting cycles — number of lifts performed per hour
• Average and maximum load — typical load versus rated capacity
• Load spectrum — distribution of loads lifted over time
• Required service life — design life in years or operating hours

Typical duty class applications:

• Light-duty (ISO A3 / FEM 1Am): General workshops, infrequent use, light loads
• Medium-duty (ISO A4–A5 / FEM 2m): Manufacturing, assembly, routine material handling
• Heavy-duty (ISO A6–A7 / FEM 3m–4m): Mining maintenance, steel plants, cement plants
• Very heavy-duty (ISO A8 / FEM 5m): Continuous production, high-frequency lifting, process cranes

Application-specific guidance:

• Mining, steel, cement and power plants may require higher-duty cranes than general workshops
• Maintenance cranes may have fewer cycles but higher average loads
• Production cranes may have more cycles but lower average loads
• The duty class affects: Hoist group rating, motor duty, brake sizing, wheel design and gearbox selection

The site power supply should be confirmed before manufacturing to avoid voltage, frequency or control-system mismatches.

Key electrical data to provide:

• Voltage: 380V / 400V / 415V / 440V / 460V (confirm at the crane connection point)
• Frequency: 50Hz or 60Hz
• Phase: 3-phase
• Voltage tolerance: Many African sites have ±10% variation — Yuantai can accommodate
• Hoist and travel motor data: Power, speed, duty rating
• VFD requirements: Required for precision, smooth travel, or heavy-duty operation
• Control panel: Location and enclosure rating
• Control method: Pendant push-button / radio remote / cabin

Common African power supply configurations:

• South Africa: 380V / 400V, 50Hz, 3Ph
• Nigeria, Kenya: 415V, 50Hz, 3Ph
• Egypt, Morocco, Algeria: 380V, 50Hz, 3Ph
• Ghana, Zambia, Angola: 400V, 50Hz, 3Ph

Electrical protection for African conditions:

• Phase failure protection: Shuts down the crane if a phase is lost
• Under-voltage protection: Protects motors during brownouts
• Surge protection: Recommended for regions with lightning risk
• Harmonic filtering: Line reactors and filters for VFD systems

The site environment has a significant impact on crane reliability and service life. African projects can expose cranes to a wide range of conditions that should be included in the specification.

Environmental factors to specify:

• Mining or cement dust: Requires IP55 or IP65 enclosures, sealed components
• High ambient temperature: Requires motor derating, Class H insulation, VFD cooling
• Rain and humidity: Requires weatherproof enclosures, corrosion-resistant materials
• Outdoor exposure: Requires wind load calculations, UV protection, rain shelters
• Coastal salt corrosion: Requires marine-grade paint, galvanized components, stainless steel fasteners
• Chemical exposure: Requires special coatings and materials

How environmental factors affect crane design:

• Motor protection: IP rating selected according to dust and moisture levels
• Electrical enclosure: IP rating, ventilation, sealing
• Cable systems: Sealed connectors, dust boots, armored cables
• Paint/coating: Corrosion protection level (ISO 12944 classification)
• VFD selection: Derated for high temperatures, forced ventilation

Temperature ranges for African regions:

• Coastal West Africa: 25–40°C with high humidity
• East Africa: 15–35°C at moderate altitudes
• Southern Africa: 5–40°C depending on season
• North Africa: 10–45°C, extreme in desert areas
• Sahel region: 20–50°C with high dust levels

Yuantai offers high-temperature options with Class H insulation, forced ventilation and derated VFDs for extreme conditions.

Typical EOT crane safety equipment should be specified to protect both personnel and equipment. The following safety devices are standard on Yuantai cranes.

Standard safety equipment:

• Overload limiter: Prevents lifting beyond the rated capacity — electronic with display
• Upper/lower hoist limit switches: Prevents over-travel of the hook block
• Cross- and long-travel limits: End-of-travel limits for trolley and bridge
• Emergency stop: Red mushroom-head push buttons on pendant, remote, and panel
• End buffers: Rubber or hydraulic bumpers at the ends of the runway
• Audible/visual warning: Horn, alarm, or flashing light during crane movement

Optional safety equipment:

• Anti-collision system: Radar or laser-based for multiple cranes on the same runway
• Load-moment limiter: For large-span cranes to prevent overturning
• Wind speed indicator: For outdoor cranes — alarms at high wind speeds
• Rail clamps: For outdoor cranes — mechanical locking during storms
• Two-level limit switches: Redundant hoist limits for critical applications

Safety standards compliance:

• Yuantai cranes are designed to meet Chinese GB standards
• ISO standards can be applied where required
• FEM standards for duty class and design
• CE marking available for applicable projects
• Local safety regulations should be checked for each African country

For a complete quotation and accurate crane design, include these parameters in the RFQ and technical specification. This gives the crane manufacturer the information needed to select the correct girder, hoist, motors, electrical system and safety equipment.

Additional documentation for larger projects:

• General arrangement drawings of the building or workshop
• Runway beam drawings or structural details
• Photos of the installation area
• Any existing crane specifications or nameplate data

Typical mechanical equipment includes wire rope hoist or open winch, drum, lifting motor, gearbox, brake, crane wheels, travel motors, couplings and hook block. The mechanical design must be matched to the load, duty cycle and operating speed requirements.

Typical configurations by capacity:

• 5–20 ton: Electric wire rope hoist, single girder EOT — standard for workshops
• 20–100 ton: Double girder EOT with trolley-mounted hoist — heavy-duty applications
• 100 ton+: Open winch trolley, often with main and auxiliary hoists — large industrial applications
• Heavy maintenance: VFD hoisting and travel for precise positioning
• Precision handling: Dual-speed or VFD control for accurate load placement

Key mechanical components and their selection criteria:

• Hoist/open winch: Capacity, lifting height, speed, duty class
• Rope drum: Diameter, grooving, rope capacity, number of falls
• Lifting motor: Power, speed, insulation class, IP rating, duty rating
• Gearbox: Ratio, torque capacity, cooling requirements
• Brake: Torque rating, temperature rating, wear monitoring
• Crane wheels: Diameter, material, tread hardness, bearing type
• Travel motors: Power, speed, duty rating, IP rating
• Hook block: Capacity, number of sheaves, hook type (C-hook, eye hook, etc.)

Example configurations:

• 50 ton mining maintenance crane: Main 50 ton hook with a smaller auxiliary hoist (10 ton) for tools, pumps or positioning work
• 100 ton steel mill crane: Open winch trolley with main and auxiliary hoists, VFD control, Class H insulation
• 10 ton workshop crane: Electric wire rope hoist, single girder, dual-speed control

Common African project supplies include 380V/50Hz/3Ph, 400V/50Hz/3Ph and 415V/50Hz/3Ph. Other voltage and frequency combinations can be engineered according to the site.

Typical electrical equipment:

• Hoist and travel motors — squirrel cage induction, Class F/H insulation
• Control panel — IP54/IP55 enclosure, main contactor, protection devices
• VFDs — for smooth acceleration, precision positioning, energy savings
• Circuit breakers — moulded-case, thermal-magnetic protection
• Contactors — AC3 rated for motor starting
• Control transformer — steps down main voltage to 24V/48V for control circuits
• Limit switches — mechanical or proximity, hoist and travel limits
• Overload limiter — electronic with display, prevents lifting beyond capacity
• Emergency stop — mushroom-head buttons on pendant, remote, and panel
• Festoon/conductor-bar system — power feed to bridge and trolley
• Radio remote — industrial-grade wireless control, dual-receiver for safety

Electrical engineering considerations:

• For a heavy-duty crane, VFD control can provide controlled acceleration and braking, which is useful when positioning a large motor, gearbox or steel component.
• Voltage tolerance: Motors and VFDs should be rated for ±10% variation to accommodate African grid conditions.
• Harmonic mitigation: Line reactors and EMC filters for VFD systems where power quality is poor.
• Phase failure and under-voltage protection: Essential for sites with unstable power supply.

Power feed options:

• Cable festoon system: Cost-effective, suitable for light to medium-duty applications
• Conductor bar system: More reliable for heavy-duty, high-frequency applications
• Choice depends on: Duty class, operating hours, speed, environmental conditions

Protection should match the actual location and environmental conditions. African projects vary widely, from dry desert areas to humid coastal regions and dusty industrial sites.

Mining and cement plants:

• Motors and electrical enclosures may require IP55 or higher where specified
• Protected cable systems — sealed connectors, metal conduits or armored cables
• Sealed electrical components — switches, sensors, and junction boxes
• Dust-resistant brakes and limit switches
• Accessible maintenance points for regular cleaning

High-temperature areas:

• Check the specified ambient temperature at the crane location
• Motor insulation — Class F standard, Class H for temperatures above 45°C
• Brake temperature rating — coils and friction materials for high temperatures
• VFD operating limits — derating required above 40°C
• Control-panel ventilation — forced ventilation or air conditioning where needed

Coastal areas:

• Paint and corrosion protection selected for the actual atmospheric conditions
• Port cranes may require a more robust coating system than cranes installed inland
• ISO 12944 classification: C4 or C5 for coastal environments
• Galvanized components, stainless steel fasteners, sealed cable glands
• Regular inspection points for corrosion monitoring

Outdoor yards:

• Specify wind loads — working wind speed (20–30 m/s) and non-working (50–60 m/s)
• Rain protection — weatherproof enclosures and drainage
• Storm parking — designated parking position and anchoring
• Rail clamps — mechanical or hydraulic for high wind protection
• Outdoor-rated electrical equipment — sealed, UV-resistant

Before shipment from China, typical inspection and testing is carried out to ensure the crane meets the design specifications and quality standards. Buyers may witness testing at the factory or request inspection reports.

Typical inspection and testing activities:

• Steel and welding inspection: Visual inspection, NDT (non-destructive testing) where specified
• Girder dimensional checks: Span, camber, straightness, connection points
• Wheel and end-carriage inspection: Dimensions, alignment, bearing fit
• Motor and gearbox checks: Speed, noise, temperature rise, oil levels
• Brake testing: Torque, response time, temperature rating
• Electrical testing: Insulation resistance, continuity, function of controls
• No-load running test: Hoisting, cross-travel, long-travel operation without load
• Load testing: Typically 100% of rated capacity, 110% or 125% as specified
• Limit-switch testing: Upper/lower limits, travel limits, emergency stops
• Overload protection testing: Verify limiter trips at the correct load
• Radio remote testing: Range, function, emergency stop, interference

Example testing scenario:

• A completed 30 ton double girder EOT crane is checked for hoisting, cross-travel and long-travel operation before shipment
• Test records are included in the project documentation package
• Buyer or third-party inspector may witness the tests

Documentation package:

• GA drawings: General arrangement showing dimensions and layout
• Structural drawings: Detail drawings of girders, end carriages, connections
• Electrical diagrams: Schematics, wiring diagrams, control panel layout
• Component datasheets: Motors, gearboxes, VFDs, brakes, hoist, etc.
• Inspection records: Steel, welding, dimensional checks
• Load-test records: Certification of load testing
• Operation and maintenance manuals: Detailed instructions for installation, operation and maintenance
• Recommended spare-parts list: For maintenance planning and future ordering

A crane kit should include the engineering information needed to fabricate and assemble the crane correctly. The wheel loads, girder dimensions, connection details and assembly tolerances are especially important when the main bridge girder is manufactured locally.

Documents provided with a crane kit:

• General arrangement drawing: Overall crane dimensions and layout
• Main girder fabrication drawing: Steel grade, plate thickness, dimensions, connection points
• End-carriage drawing: Wheelbase, connection details, tolerances
• Wheel-load data: Maximum and minimum wheel loads for runway design
• Structural calculations: Where required for the local fabricator
• Electrical schematic: Wiring diagram and control logic
• Component datasheets: Motors, gearboxes, VFDs, hoist, brakes
• Installation instructions: Step-by-step assembly guide
• Testing procedure: Load testing, limit checks, functional testing
• Spare-parts list: Recommended spare parts for maintenance
• Operation and maintenance manual: For ongoing crane operation

Critical coordination points before fabrication:

• The Chinese supplier and African fabricator should agree on the steel grade before cutting steel
• Welding procedure and quality standards should be defined
• Dimensional tolerances must be clearly specified — especially wheelbase and girder connection points
• Wheel alignment is critical for smooth crane travel
• Electrical installation responsibilities and testing responsibilities should be assigned

The kit can be engineered for a wide range of industrial applications. The final values should be calculated from the actual crane duty, load spectrum, building structure and operating environment.

Which Parts Can Be Fabricated Locally?

For an EOT crane kit, the African contractor can often fabricate the following locally:

• Main girder: Single or double girder bridge structure
• Platforms and walkways: For maintenance access
• Ladders and handrails: Safety access equipment
• Gantry legs: For gantry crane kits
• Structural supports: Bracing, stiffeners, connection brackets

Before cutting steel, confirm:

• Steel grade (e.g., Q345B or equivalent)
• Plate thickness and girder dimensions
• Overall length and wheelbase
• Connection dimensions — must match imported end carriages
• Welding requirements and quality standards
• Deflection limits (typically L/700–L/1000)
• Paint system and corrosion protection

The locally fabricated girder must match the imported end carriages, hoist and trolley precisely.

A crane kit reduces the amount of structural steel shipped from China. This can be particularly useful for projects far from major ports or where shipping costs are high.

Main advantages of the crane kit model:

• Lower shipping volume: The steel girder is the largest and heaviest component — fabricating it locally reduces container requirements
• Local steel and labor: Uses locally available materials and creates local employment
• Easier transport to inland sites: Fabricating the girder near the site avoids transporting long steel sections from the port
• Local installation and maintenance: Local teams can install and maintain the crane more easily
• Easier future structural repairs or modifications: Local expertise can extend the crane's service life
• Reduced import duties: Import duties may be lower on mechanical/electrical components than on complete steel structures

Important Checks Before Assembly

The imported mechanical parts and locally fabricated structure must match precisely. Check the following before assembly:

• Wheel gauge: Distance between rails on the bridge — must match runway gauge
• End-carriage wheelbase: Distance between front and rear wheels on each end carriage
• Girder connections: Bolting or welding details must match
• Wheel loads: Verify against runway beam capacity
• Deflection: Check calculated deflection against the design limit
• Trolley rails: Alignment and connection for the trolley travel
• Hoist mounting: Position and connection details must match
• Cable routing: Festoon or conductor bar alignment
• Buffers and limit-switch positions: Must be correctly positioned for safe operation

The Chinese crane supplier should approve the fabrication drawings before local steel production. This helps prevent wheel-alignment, assembly and crane-travel problems.

For African mining and cement plants, a typical kit may include heavy-duty components suitable for demanding conditions.

Typical mining/cement crane kit:

• Capacity: 20–100 ton+ double girder bridge mechanism
• Hoist: Electric wire rope hoist or open winch trolley
• End carriages: Heavy-duty with forged wheels and sealed bearings
• Travel drives: Motors and gearboxes matched to the duty class
• VFDs: For controlled hoisting and travel
• Overload limiter: Electronic with display
• Radio remote: For safe operation
• Control panel: IP55 enclosure with sealed cable entries

Additional protection for cement and mining sites:

• Dust protection: IP55 or IP65 electrical components, sealed enclosures
• High-temperature considerations: Class H insulation, derated VFDs
• Easier maintenance access: Platforms, walkways and service points
• Corrosion protection: Suitable paint system for the site conditions

The choice between a complete crane and a crane kit depends on the buyer's local capabilities, project location and supply chain preferences.

A complete crane is usually simpler for customers that want one supplier to handle the whole system — from design and fabrication to factory testing and shipment.

A crane kit is more suitable when the African buyer or EPC contractor has qualified local fabricators, installation equipment and crane engineering experience.

Before ordering an EOT crane kit, clearly define what Yuantai supplies and what the local contractor fabricates or installs. A clear division of work helps the Chinese supplier and African contractor coordinate fabrication, installation and testing.

Key responsibilities to assign:

• Steel fabrication: Who fabricates the main girder, platforms and supports?
• Mechanical assembly: Who assembles the crane on site?
• Electrical installation: Who installs the control panel, cables and power feed?
• Runway work: Who provides the runway rails, beams and foundation?
• Welding inspection: Who inspects and certifies the welding?
• Painting: Who applies the paint and corrosion protection?
• Load testing: Who carries out load testing and commissioning?
• Local certification: Who obtains local safety and regulatory certification?
• Spare parts: Who supplies and stocks spare parts?
• Warranty service: Who provides warranty support?

Data the buyer should provide:

• Capacity: 1–550 ton+, as required
• Span: Runway rail center distance
• Lifting height: Required hook height
• Duty class: ISO / FEM classification
• Runway gauge: Rail-to-rail distance
• Building dimensions: Span, headroom and runway elevation
• Power supply: Voltage / frequency / 3Ph
• Operating hours and lifting cycles: For duty class verification
• Indoor or outdoor operation: Affects protection requirements
• Temperature, dust, humidity and corrosion conditions: For component selection

Critical technical data for the kit:

• Wheel loads: Maximum and minimum loads for runway design
• Girder connection dimensions: Where the girder connects to end carriages
• Hoist mounting details: Position and attachment points
• Electrical interface points: Power feed, control cable routing

Defining these details clearly helps keep critical components such as the hoist, drives, wheels, brakes and control system matched to the crane design while allowing the local contractor to fabricate the steel structure efficiently.

Yuantai can configure the crane around the actual African site. Key data includes:

• Capacity: 1–550 ton+
• Span: Project-specific
• Lifting height: Project-specific
• Duty: ISO / FEM
• Hoisting/travel speed: Single speed, dual speed or VFD
• Power: Commonly 380/400/415V, 50Hz, 3Ph
• Control: Pendant / radio remote / cabin
• Environment: Indoor / outdoor, dust, heat, humidity and corrosion

For existing workshops, the design can be checked against runway gauge, headroom, rail elevation and allowable wheel loads.

Where local contractors have steel fabrication and installation capability, Yuantai can supply the critical crane components while the main girder and selected steelwork are fabricated locally.

A typical kit may include end carriages, wheels, travel motors and gearboxes, electric wire rope hoist, hoist trolley, control panel, VFDs, festoon system, pendant/radio remote, safety devices and technical drawings.

For example, a 10–50 ton workshop EOT crane can use locally fabricated bridge steel with imported mechanical and electrical components, provided the girder dimensions, wheelbase, wheel loads and connection details match the approved design.

For existing cranes, Yuantai can supply wire rope hoists, motors, gearboxes, wheels, end carriages, brakes, control panels, VFDs, festoon systems, limit switches, radio remotes and overload limiters.

Modernization can include hoist replacement, VFD installation, control-panel upgrades, radio-control conversion and safety-system upgrades.

Replacement parts should be matched to the existing capacity, duty class, dimensions, voltage, speed and mechanical interfaces.

For a faster and more accurate quotation, provide:

• Capacity, span, lifting height, duty class
• Runway gauge and length
• Power supply
• Operating hours and lifting cycles
• Indoor/outdoor conditions and temperature
• Control preference
• Site drawings or photos

For replacement projects, also provide the existing crane nameplate, hoist dimensions, motor data and component photos.

With these details, Yuantai can define the crane configuration, technical scope, supply boundary and required components before manufacturing.

An EOT crane travels on runway beams attached to a building structure. A gantry crane travels on ground rails using legs that support the bridge.

EOT cranes are commonly used inside workshops and factories. Gantry cranes are useful for outdoor yards, construction sites, steel yards and equipment storage areas.

Mining maintenance usually requires a heavy-duty double girder EOT crane when large equipment such as motors, gearboxes, crushers and pumps must be lifted.

The final selection depends on the maximum maintenance load, duty class, lifting height, span and operating frequency. Dust protection and suitable electrical enclosures should also be considered.

For cement plants, the crane should be selected according to the maintenance load and working cycle. Single girder EOT cranes can handle general workshop work, while double girder or heavy-duty EOT cranes are more suitable for heavier equipment such as motors, gearboxes, crushers and plant components.

Dust protection, temperature and maintenance access should be included in the specification.

Steel factories may require single girder, double girder or heavy-duty overhead cranes, depending on the load.

Double girder cranes are commonly considered for heavier steel handling, machinery maintenance and production areas. The design should also consider lifting frequency, steel temperature, working environment and required positioning accuracy.

Yes. The crane electrical system can be configured according to the project power supply.

Typical specifications may include:

• 380V / 50Hz / 3Ph
• 400V / 50Hz / 3Ph
• 415V / 50Hz / 3Ph
• Project-specific voltage and frequency

The actual site power supply should be confirmed before manufacturing.

Yes. A complete supply can include crane design, structural fabrication, hoist, travelling mechanisms, electrical controls, safety devices, factory testing, export packing and technical support for installation and commissioning.

Yes. A crane kit can include the hoist, end carriages, wheels, motors, gearboxes, control panel, electrical system, safety devices and technical drawings.

Local contractors can fabricate selected steel structures, such as the main girders, according to the approved drawings.

Yes. Replacement equipment can include:

• Electric wire rope hoists
• Motors
• Gearboxes
• Crane wheels
• End carriages
• Brakes
• Control panels
• VFDs
• Limit switches
• Radio remote controls
• Overload limiters

Existing crane dimensions and technical data should be checked before selecting replacement components.

The basic quotation data should include:

• Lifting capacity
• Span
• Lifting height
• Duty class
• Runway length
• Power supply
• Hoisting and travel speeds
• Control method
• Indoor or outdoor operation
• Ambient temperature
• Dust, humidity or corrosion conditions
• Building or runway drawings, if available

For replacement projects, provide the existing crane nameplate, photos, drawings and component dimensions where possible.

A single girder EOT crane is generally suitable for light and medium-duty applications, workshops and general material handling. A typical range is around 1–20 ton, subject to project design.

A double girder EOT crane is better suited to heavier loads, higher duty cycles and applications requiring greater lifting height or more robust hoist arrangements. Yuantai's referenced range can extend from about 20 to 550 ton, depending on the project.

The decision should be based on capacity, span, duty class, lifting height, headroom, operating frequency and total crane cost, rather than capacity alone.
