Crane Supplier for Kazakhstan, Uzbekistan, Azerbaijan & Georgia

Capacity: 20–550 ton  |  Span: 10–35 m+  |  Lifting height: 8–30 m+  |  Duty: FEM M6–M8

Engineered for mining concentrator maintenance bays, steel plants, cement plants, heavy fabrication and oil & gas workshops. The double girder overhead crane price is significantly influenced by wheel load calculations, VFD drives, open-winch hoisting, and PLC-based automation. For capacities above 20 tons, this configuration is almost always mandatory. Additional cost drivers include anti-sway technology, synchronized lifting systems, and load-cell weighing – features that add 10–30% but are critical for precision handling and process safety.

Ideal for workshops where floor-supported runway columns are not feasible. The under-running crane hangs from the roof steelwork, freeing up floor space for production equipment – common in older Uzbek and Georgian factory buildings with limited column space.

Price drivers: Roof beam capacity, wheel load distribution, runway alignment, and available headroom. Because the building structure must carry the crane's dynamic loads, Yuantai provides wheel load data and runway reaction calculations to support structural verification. This configuration often costs 10–20% less than a top-running crane of the same capacity, but structural reinforcement costs can offset that saving – so we always recommend a site structural review before finalizing.

Application: Oil & gas, chemical plants, paint shops, and grain storage  |  Certification: ATEX / IECEx / CNEX as specified (Zone 1/2, Gas Groups IIA/IIB/IIC)

The explosion-proof overhead crane price is 40–80% higher than a standard unit due to spark-proof materials, sealed enclosures (IP65+), temperature-rated motors, and certified electrical components. Every detail – from the hoist brake to the radio remote control – must comply with hazardous area regulations. This is particularly relevant for Azerbaijan Caspian energy projects and Kazakh western oil & gas facilities. Price also varies with temperature class (T1–T6) and gas group – the more severe the zone, the more rigorous the engineering.

For clients with local fabrication and installation capabilities, Yuantai offers knock-down crane kits. This approach reduces freight volume, lowers import duties, and leverages regional labor – often cutting total landed cost by 15–30%. This is especially relevant for landlocked Central Asian markets where inland freight from Chinese ports is a major cost factor.

What's included: Hoist (motor + gearbox), end carriages, travel motors, gearboxes, electrical control panel, pendant/radio control, conductor bars, limit switches, and overload protection.

Price drivers: The kit price depends on hoist capacity, electrical complexity (VFD vs. DOL), and certification requirements. Buyers typically source bridge girders locally – we provide interface drawings, wheel load tables, and bolt patterns to ensure precise fit. This is a popular option for EPC contractors and steel fabricators across Kazakhstan and Uzbekistan.

Two cranes with the same rated capacity can have completely different price tags. The factors below are the ones that move the number most:

① Capacity (ton) – Higher capacity = larger girders, heavier hoists, stronger motors.
② Span (m) – Wider span requires deeper girders and larger wheels.
③ Lifting height (m) – More rope drum wraps and longer wire rope.
④ Duty classification (FEM/ISO) – M3 vs. M8 changes motor sizing, brake torque, and electrical duty.
⑤ Control system – Pendant (cheapest) → Radio (mid) → Cabin + PLC (most expensive).
⑥ VFD vs. DOL – Variable-frequency drives add 10–20% but save energy and reduce shock.
⑦ Environmental protection – Low-temp steel, IP55/IP65, C5 corrosion coating, heat-resistant paint.
⑧ Hazardous area certification – ATEX/IECEx/CNEX adds significant cost (40–80%).
⑨ Advanced features – Anti-sway, sync-lift, load cells, condition monitoring.
⑩ Certification & testing – Third-party inspection, load testing, NDT, and documentation.

Pro tip: Send us your actual load spectrum, cycles per hour, and operating hours – not just max tonnage. We'll size the crane right-sized for your real duty, avoiding over-specification (wasted cost) or under-specification (safety risk).

In steel processing and bulk material handling, the crane is defined by its lifting attachment, not just its capacity. A hook crane cannot safely replace a ladle crane, and a standard double girder crane cannot handle bulk material efficiently without a grab. These are the crane families most relevant to Kazakh steel plants and Uzbek building materials plants.

Ladle crane (casting crane)
Used in steelmaking bays to lift and pour molten metal ladles. Requires very high duty class (FEM M7–M8), heat shielding, redundant braking, slow and precise hoisting, and strict safety redundancy. This is a process-critical crane – not a maintenance crane. Typical capacity: 100–400+ ton.

Magnet crane
Used to handle steel scrap, billets, plates and coils with an electromagnetic spreader. Requires reliable power supply to the magnet, VFD travel control, and protection against load swing. Typical capacity: 10–100 ton.

Grab crane
Used to handle bulk material such as cement clinker, coal, ore, sand and fertilizer with a clamshell or orange-peel grab. Requires heavy-duty hoisting mechanism, dust protection, and a duty class matched to continuous bulk handling. Typical capacity: 5–50 ton.

Key point: A steel plant may need a ladle crane for the melting bay, a magnet crane for the scrap yard, and a standard double girder crane for the maintenance workshop – three different crane types in one plant. Yuantai evaluates the actual material, process and duty before recommending the attachment and crane structure.

Not every heavy lifting job happens inside a workshop. In Georgian port terminals, the Kazakh Caspian port of Aktau, and Uzbek logistics hubs, heavy loads are handled in open or semi-open yards where an overhead crane cannot be supported by a building structure. This is where heavy-duty gantry cranes become the correct solution.

Typical gantry crane types for the region:

• Rail-mounted gantry crane (RMG) – Container yards and rail terminals; high duty, automated positioning
• Rubber-tyred gantry crane (RTG) – Flexible container yard handling; diesel or hybrid drive options
• General-purpose double girder gantry crane – Outdoor storage, steel stockyards, precast yards, maintenance areas
• Semi-gantry crane – One leg on a rail, one leg on an existing building column; useful where space is constrained

Design factors specific to this region:

• Wind load – Open yards in steppe and coastal areas require wind-load calculation and rail clamps / anchoring
• Corrosion – Caspian and Black Sea ports require C4/C5 coating and corrosion-resistant hardware
• Seismic – Georgian and Azerbaijani port projects may require seismic verification of the gantry structure
• Foundation – Rail foundation and wheel loads must be coordinated with civil works
• Outdoor electrical protection – IP55+ enclosures, anti-condensation heaters, UV-rated cables

Note: Gantry cranes are not a substitute for overhead cranes in a workshop, and overhead cranes are not a substitute for gantry cranes in a port yard. The project location and building condition determine which family applies.

A heavy-duty crane requires far more than simply increasing the motor size. The following engineering factors determine whether a crane will survive continuous shift operation in a Central Asia or Caucasus industrial environment:

• Load spectrum – Determines how much of the crane's rated capacity is actually used during operation
• Operating hours – More operating hours increase mechanical and electrical duty
• Lifting cycles – Frequent starts/stops increase brake, motor and gearbox loading
• Duty classification – ISO/FEM classification must reflect actual utilization and load spectrum
• Bridge or gantry structure – Higher loads require appropriate girder stiffness and structural capacity
• End carriages & wheels – Heavy cranes generate significant wheel and runway loads
• Hoisting mechanism – Open winch or heavy-duty wire rope hoist selected according to capacity and duty
• Lifting attachment – Hook, ladle, magnet, grab or lifting beam, selected to the actual material
• Brakes – Brake capacity and service life must match the lifting mechanism
• Gearboxes – Gearbox rating must account for operating cycles and load conditions
• VFD control – Reduces mechanical shock and improves acceleration/deceleration
• Thermal design – Motor and electrical components must suit both high summer heat and low winter temperatures (e.g., –40°C in northern Kazakhstan)
• Seismic design – Relevant for projects in Azerbaijan, Georgia, Uzbekistan and Kyrgyzstan

For example, a 100-ton crane operating in a high-dust Kazakh concentrator may require greater attention to electrical enclosure protection (IP65+), low-temperature steel and lubricants, and maintenance access than a similar-capacity crane in a clean workshop.

Yuantai heavy-duty cranes can be engineered with a wide range of advanced features to match the specific demands of Central Asian mining, steel, oil & gas, manufacturing and port projects:

• Double-girder bridge – Standard for capacities above 20 tons
• Heavy-duty wire rope hoist – Compact and reliable for most applications
• Open winch hoisting mechanism – Preferred for very high capacities and process cranes
• Ladle, magnet and grab attachments – Selected to the actual material
• VFD hoisting and travel control – Smooth acceleration, precise positioning, reduced mechanical stress
• PLC control – For automation, diagnostics, and process integration
• Radio remote control – Enhanced operator safety and visibility
• Operator cabin – For high-frequency or high-precision applications
• Synchronized lifting – For tandem or multi-point loads
• Anti-sway control – Precise load placement at high speeds
• Overload protection – Load cells and limit switches for safety
• Upper and lower lifting limits – Prevents over-travel
• Travel limit protection – End-stroke safety
• Heavy-duty brakes – Sized for continuous duty and high inertia loads
• High-capacity wheels and end carriages – Designed for heavy wheel loads
• Long-span bridge design – Up to 35 m+ spans
• Special lifting beams, C-hooks – Customized to the load

Example: A crane handling long steel beams may benefit more from VFD travel control, radio remote operation, and a properly designed lifting beam than simply increasing the crane's rated capacity. A crane handling two lifting points simultaneously may require synchronized lifting control – a feature that adds significant value in steel fabrication and heavy machinery assembly.

For heavy Central Asia and Caucasus industrial projects, buyers often encounter both heavy-duty wire rope hoist cranes and open-winch cranes. The correct choice depends on the required capacity, duty, lifting speed, lifting height, operating frequency, and process requirements – not capacity alone.

Comparison guide:

• Heavy-Duty Wire Rope Hoist – Typical application: workshops and general heavy lifting. More compact, generally simpler maintenance, suitable for many capacities. Moderate to high customization.
• Open Winch – Typical application: heavy industrial/process applications. Larger mechanism, more components but serviceable. Particularly suitable for very high capacities and process cranes. Strong choice for demanding applications.

Key point: A 50-ton open-winch crane may be the right choice for a continuous mining or steel plant operation, while a 50-ton wire rope hoist crane could be perfectly adequate for intermittent maintenance lifting in the same plant. Yuantai evaluates the actual load spectrum and operating profile to recommend the optimal hoisting mechanism.

Example 1 – Kazakhstan Concentrator Maintenance Bay
Capacity: 100 ton  |  Span: 28 m  |  Lifting height: 15 m
Operation: Multiple shifts  |  Environment: High dust, low winter temperature

In this case, the design must consider not only the 100-ton SWL but also dust protection, low-temperature steel and lubricants, duty classification, wheel loads, runway structure, motor thermal conditions, gearbox selection, and maintenance access – all of which are critical for reliable operation in a harsh mining environment.

Example 2 – Uzbekistan Steel Fabrication Plant
Capacity: 50 ton  |  Span: 25 m  |  Lifting height: 12 m
Operation: 2 shifts/day  |  Load: Steel structures and fabricated sections
Control: Radio remote  |  Environment: Indoor, dusty

A suitable starting point would be a 50-ton double-girder EOT crane with VFD travel/hoisting control, with the final duty classification calculated from the actual lifting cycle.

Example 3 – Kazakhstan Steel Plant Casting Bay
Capacity: 200 ton  |  Span: 30 m  |  Lifting height: 20 m
Load: Molten metal ladle  |  Duty: Continuous, FEM M8

This requires a dedicated ladle crane with heat shielding, redundant braking, slow precise hoisting and strict safety redundancy – a very different machine from a general double girder crane of the same capacity.

Example 4 – Georgia Port Container Yard
Capacity: 40 ton  |  Span: 25 m  |  Lifting height: 18 m
Load: Containers  |  Environment: Coastal, outdoor

This requires a rail-mounted or rubber-tyred gantry crane with C5 corrosion protection, wind-load calculation and seismic verification – not an overhead crane.

Yuantai supplies customized heavy-duty cranes for 20–550 ton applications, with double-girder configurations used as the normal starting point for cranes above 20 tons. The final crane is engineered around the actual project – not simply selected from a capacity table.

For Central Asia and Caucasus projects, particular attention is given to:

• Low winter temperature – Low-temp steel, lubricants, heated cabinets (critical in northern Kazakhstan)
• High summer temperature – Motor insulation, oil viscosity, cooling
• Desert and steppe dust – IP ratings, enclosure protection, maintenance intervals
• Seismic activity – Seismic design verification where required (Azerbaijan, Georgia, Uzbekistan, Kyrgyzstan)
• Hazardous areas – ATEX/IECEx/CNEX certification, Zone, Gas Group, Temperature Class
• Long-span buildings – Structural integration and runway design
• Multi-shift operation – High-duty components and redundant systems
• Landlocked logistics – Container vs. breakbulk planning, inland freight to Kazakhstan and Uzbekistan

For a technical quotation, provide:
Capacity (max and average load), Span (runway center distance) or gantry rail gauge, Lifting height (floor to upper hook position), Crane travel length, Load type (steel, ladle, bulk, container, machinery, etc.), Operating hours/day, Lifting cycles per hour (average & peak), Power supply (voltage/frequency/phase), Installation environment (indoor/outdoor, dusty, corrosive, low temperature, etc.), and Hazardous-area requirements (if any).

These details are far more useful than specifying only "100-ton heavy-duty crane". The more detailed the input, the more precise the engineering output – including girder type, hoist selection, lifting attachment, motor sizing, braking torque, wheel load calculations, and control architecture.

Typical lead time: a configured EOT crane is usually delivered 60–90 days after drawing approval. Gantry cranes and ladle cranes, which involve more structural fabrication and testing, may require 90–120 days. Lead time starts from approved drawings, not from the initial inquiry.

Yuantai manufactures heavy-duty cranes in China and supplies them to mining, steel, manufacturing and port projects across Central Asia and the Caucasus.

Northern Kazakhstan and mountainous regions can experience winter temperatures approaching –40°C. If a project specifies a minimum ambient temperature this low, this value must be included in the crane technical specification before equipment is selected.

Engineering measures for low-temperature environments:

• Structural steel – Low-temperature impact-tested steel where required
• Hoisting motor – Rated for specified ambient temperature and operating duty
• Travel motors – Thermal load checked under repeated acceleration and braking
• VFD – Actual ambient-temperature derating and enclosure conditions verified
• Control cabinet – Anti-condensation heaters and thermal insulation where required
• Brake – Thermal capacity checked for lifting cycle and ambient conditions
• Gearbox – Low-temperature lubricant and thermal performance
• Cables – Low-temperature-rated cable where required
• Lubricants – Suitable viscosity and temperature range
• Electrical components – Manufacturer's allowable ambient temperature verified

Best RFQ example:
"20 ton / 20 m span / 10 m lift / –30°C to +40°C ambient / 10 cycles per hour / 16 h per day"

Important: –40°C ambient temperature does not automatically mean every crane component must be rated to –40°C without further analysis. Component derating, enclosure heat dissipation, and the actual duty cycle should all be checked.

Fine dust and wind-blown sand can affect electrical equipment, motors, brakes, and control systems. For cranes operating in Kazakh steppe, Uzbek desert, or Turkmen desert environments, Yuantai considers:

• IP55/IP65 electrical enclosures where required
• Enclosed electrical cabinets
• Protected cable-entry systems
• Dust-resistant electrical components
• Suitable motor protection
• Sealed or protected control devices
• Protected conductor or festoon systems
• Appropriate cable routing
• Accessible maintenance points
• Inspection and cleaning provisions

Examples by installation type:

• Indoor workshop – Provide dust level and ventilation details
• Outdoor crane / gantry – Provide dust + rain + UV + wind + temperature details
• Desert yard – Provide wind-blown sand and dust exposure details
• Cement plant – Provide fine process dust details
• Mining facility – Provide dust type and concentration details
• Caspian coastal plant – Provide dust + humidity + salt exposure details

Cranes installed near Caspian ports, Black Sea terminals, shipyards, coastal factories, petrochemical plants, and marine logistics areas can experience humidity and salt-air exposure. This is particularly relevant to Azerbaijan, Georgia and Kazakhstan's Caspian coast.

Corrosion protection should be considered for the entire crane or gantry – not treated as a paint-color decision.

Possible corrosion-protection measures:

• Structural steel – Multi-layer coating system
• Surface preparation – Specified blasting/preparation grade
• Exposed steel – C4/C5 coating system where required
• Fasteners – Stainless or corrosion-resistant hardware where appropriate
• Small components – Galvanized treatment where practical
• Electrical cabinets – Corrosion-resistant enclosure
• Cable systems – Protected cable/festoon arrangement
• Outdoor components – Additional weather and corrosion protection

Buyer example: Instead of "Paint: standard," provide:
"Installation: Caspian coastal industrial area, approximately 500 m from sea, outdoor/semi-outdoor, high humidity and salt exposure."

Many Central Asia and Caucasus projects are located in seismic zones – including parts of Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Azerbaijan, Georgia and Armenia. Seismic design may be required by the project specification or local building code.

Seismic design measures may include:

• Structural verification – Crane, gantry and runway checked against seismic loads
• Wheel/rail restraint – Anti-derailment devices where required
• Buffer and end-stop design – Sized for seismic displacement
• Anchor and connection design – Verified for seismic forces
• Control system – Seismic-triggered stop where specified

What the buyer should provide: the seismic zone, design code, and required seismic acceleration parameters. Without this information, the supplier cannot verify the crane design.

A crane's capacity does not by itself determine whether it is "heavy duty." Consider two 50-ton cranes:

Crane A – 50 ton capacity, 8 lifting cycles/day, maintenance application, 8 operating hours/day

Crane B – 50 ton capacity, 15 lifting cycles/hour, 16 operating hours/day, mining production, multiple shifts

Although both cranes are rated 50 tons, their mechanical and electrical requirements can be significantly different.

Parameters used to determine duty:

• Rated capacity – e.g., 50 ton
• Average lifted load – e.g., 30 ton
• Maximum lifted load – e.g., 50 ton
• Lifting cycles/hour – e.g., 15
• Operating hours/day – e.g., 16 h
• Shifts/day – e.g., 2
• Working days/year – e.g., 300
• Average lifting distance – e.g., 8 m
• Average travel distance – e.g., 30 m
• Required service life – Project-specific
• Working environment – e.g., mining production
• Control frequency – Frequent start/stop

These parameters help determine the appropriate ISO/FEM duty classification, motor rating, brake selection, gearbox rating, wheel loads, and structural design.

For higher-capacity and high-utilization applications, Yuantai can engineer:

• Double-girder bridge structures – Standard for capacities above 20 tons
• Double-girder gantry structures – For outdoor yards and ports
• Heavy-duty wire rope hoists
• Open-winch hoisting mechanisms – Preferred for very high capacities and process cranes
• Ladle, magnet and grab attachments – Selected to the actual material
• Heavy-duty motors
• Heavy-duty gearboxes
• Higher-performance brakes
• VFD-controlled lifting – Smooth acceleration, precise positioning
• VFD-controlled trolley and crane travel – Reduced mechanical shock
• Heavy-duty wheels and end carriages
• Radio remote control
• Operator cabin
• PLC control – For automation, diagnostics, and process integration
• Synchronized lifting – For tandem or multi-point loads
• Position monitoring
• Limit-control systems
• Overload protection – Load cells and limit switches for safety

For cranes above 20 tons, Yuantai generally starts with a double-girder configuration for heavy-duty applications. The final configuration is determined by the project load, span, duty, lifting height, and structural requirements.

One common purchasing mistake is to specify "Heavy duty — A8" without providing the operating data needed to justify that classification. Duty classification should be established from the load spectrum and operating frequency.

The manufacturer should consider:

• Average load
• Maximum load
• Number of lifting cycles
• Operating hours
• Load distribution
• Travel frequency
• Acceleration and braking cycles
• Expected service life

Depending on the applicable design methodology, the crane may be classified using ISO/M or FEM classifications. These classifications should not simply be treated as interchangeable labels.

Buyer example: A maintenance crane that lifts a motor occasionally may require a substantially different duty classification from a production crane lifting mining equipment throughout a 24-hour operation.

Therefore, an EPC specification should ideally state the actual operating cycle and require the supplier to confirm the resulting duty classification in the technical proposal.

A specification such as "20-ton EOT crane × 20 m span × 10 m lift" is a useful starting point, but it is not yet a complete engineering specification.

The following information can change the crane design and price:

• Capacity – Hoist and bridge structure
• Span or rail gauge – Girder design and wheel loads
• Lifting height – Drum, rope and hoist arrangement
• Load type – Hook, ladle, magnet, grab or lifting beam
• Load spectrum – Duty classification
• Lifting cycles – Motor and brake sizing
• Operating hours – Thermal and service-life requirements
• Ambient temperature – Motor/electrical selection (both low and high)
• Dust – Enclosure and equipment protection
• Coastal exposure – Coating and corrosion protection
• Seismic zone – Structural verification
• Hazardous area – Ex equipment and certification
• Power supply – Motors, VFDs and electrical system
• Control method – Pendant, radio, cabin or PLC
• Building or yard structure – Runway and wheel-load requirements
• Installation conditions – Crane dimensions and maintenance access

This is why Yuantai approaches Central Asia and Caucasus projects from the working conditions first – and the crane model second.

A detailed technical specification helps avoid three common problems:

• Under-specification – The crane is not properly designed for the actual environment or duty.
• Over-specification – Expensive features are included that the application does not actually require (e.g., a heavy-duty metallurgical crane specified for a standard Uzbek workshop).
• Quotation changes later – Critical information such as –40°C ambient temperature, seismic zone, hazardous-area classification, 380 V power supply, or Caspian coastal exposure is discovered after the technical offer has already been prepared.

Yuantai's approach is simple:
Define the load → define the operating cycle → define the environment → define the building or yard → define the electrical system → then select the crane configuration.

For Central Asia and Caucasus industrial projects, this approach provides a more reliable basis for selecting the crane structure, hoist, lifting attachment, motors, brakes, electrical protection, control system, corrosion protection, seismic design, and duty classification.

Yuantai manufactures cranes in China and supplies them to industrial projects across Central Asia and the Caucasus.

Reliable. Customized. Compliant. Delivered on Time.

Instead of writing "Supply one 50-ton crane according to international standards," a better RFQ specification would state:

• Crane type: double girder EOT
• Capacity: 50 ton
• Span: 25 m
• Lifting height: 12 m
• Working hours: 8–16 hours/day
• Lifting cycles: to be confirmed
• Application: steel fabrication
• Indoor/outdoor: indoor
• Ambient temperature: –20°C to +40°C
• Seismic zone: to be confirmed
• Power supply: 380 V, 50 Hz, 3 Ph
• Design basis: applicable Chinese GB/T standards, with specified international requirements where applicable
• Documentation: GA drawing, calculations, electrical drawings, component list, FAT and test records

This gives the manufacturer enough information to design the crane – rather than simply selecting a standard model from a catalog.

Central Asia and Caucasus projects may also refer to ISO, FEM, DIN, IEC, EN, GOST, or the customer's own engineering standards. These standards should not be described as automatically interchangeable – they often address different aspects of crane design and operation. GOST standards are particularly relevant in Kazakhstan and other CIS markets.

Practical approach – establish a design basis document:

• Crane structure – Yuantai: GB/T standards | Project may require: ISO / FEM / DIN / GOST / project specification
• Duty classification – Yuantai: Chinese design basis | Project may require: ISO/FEM classification if specified
• Electrical system – Yuantai: GB/T / applicable IEC requirements | Project may require: IEC / EN / GOST / customer standard
• Motors – Yuantai: Chinese standards | Project may require: IEC / GOST / customer-approved brand
• Control system – Yuantai: Chinese engineering practice | Project may require: IEC / project specification
• Safety devices – Yuantai: GB/T requirements | Project may require: ISO / EN / GOST / project requirements
• Inspection – Yuantai: Chinese inspection requirements | Project may require: Customer ITP / third-party inspection
• Explosion protection – Yuantai: Chinese Ex requirements | Project may require: CNEX / ATEX / IECEx as specified
• Documentation – Yuantai: Chinese manufacturing records | Project may require: EPC document requirements

The buyer should ask the manufacturer to clearly state which standards apply to each engineering area.

CE is one of the most frequently requested requirements for exported industrial equipment. However, CE is not the same thing as FEM, ISO, or a crane duty classification. CE relates to conformity with applicable European Union requirements.

For a crane project, the buyer should clarify whether the project requires:

• CE marking
• Declaration of Conformity
• Technical documentation
• Risk assessment
• Electrical documentation
• Safety documentation
• Operating instructions
• Test records
• Specific European standards

Example – CE requirement for a Georgian or Azerbaijani EPC project:
Suppose an EPC contractor writes "Crane shall be CE certified." Before ordering, the buyer should ask: Which CE requirements are included in the project specification?

• Is CE marking required on the complete crane?
• Which European legislation applies?
• Are specific EN standards listed?
• Is a Declaration of Conformity required?
• Is a third-party conformity assessment required?
• What technical documents must be submitted for approval?

What the buyer should request:
For a CE-required project, include a document list in the RFQ, for example:
"CE documentation required: Declaration of Conformity, technical documentation, electrical drawings, safety information, operating manual, test records, and applicable component documentation."

ISO certification is different from CE certification. For a crane buyer, ISO is most useful when it is connected to the manufacturer's quality-management and production-control system.

A properly controlled crane manufacturing process should include inspection at different stages rather than relying only on a final inspection before shipment.

Typical quality-control points:

Raw Material: Steel grade verification, material certificates, incoming inspection, traceability where required

Structural Fabrication: Cutting and preparation, welding procedure control, welder qualification where required, dimensional inspection, weld inspection, girder straightness and alignment

Mechanical Assembly: Gearbox inspection, wheel alignment, brake inspection, hoist assembly, coupling and shaft inspection, end-carriage assembly

Electrical Assembly: Motor verification, VFD inspection, control cabinet wiring, insulation checks, electrical function testing, limit-switch testing

Final Testing (depending on project): No-load testing, rated-load testing, overload testing where specified, hoisting test, cross-travel test, long-travel test, brake test, limit-switch test, emergency-stop test, control-system test

What the buyer should do:
Do not simply ask "Is your factory ISO certified?" Also ask for:
"Please provide your ISO certificate and explain the inspection and quality-control procedures applicable to this crane project."

For an EPC project, it is also useful to request an Inspection and Test Plan (ITP) before manufacturing begins.

For hazardous-area applications, certification becomes much more important. Typical applications include Kazakh oil & gas facilities, Azerbaijan Caspian energy plants, Uzbek gas-processing plants, and Turkmen petrochemical facilities.

Yuantai can provide explosion-proof crane configurations using appropriately certified Ex components, with CNEX certification applicable to relevant explosion-proof products. CNEX is particularly relevant to buyers purchasing explosion-proof equipment manufactured in China.

Possible protection concepts include:

• Ex d – Flameproof enclosure
• Ex de – Combination of flameproof and increased-safety
• Ex t – Protection by enclosure for combustible dust atmospheres
• Other applicable protection methods

Important: Buyers should not select an explosion-proof crane simply by saying "We need an Ex crane." The hazardous-area requirements must first be established.

A better inquiry for an explosion-proof crane would provide:

• Capacity: 10 ton
• Span: 18 m
• Lifting height: 8 m
• Application: oil & gas maintenance workshop
• Ambient temperature: –25°C to +45°C
• Power supply: 380 V / 50 Hz / 3 Ph
• Area classification: Zone 1
• Gas group: IIB
• Temperature class: T4
• Required certification: to be confirmed according to project specification
• Duty: 8 hours/day
• Control: explosion-proof pendant / radio remote as required

This information allows the crane manufacturer to select the appropriate:

• Explosion-proof hoist
• Motor
• Brake
• Electrical cabinet
• Pendant
• Limit switches
• Cable system
• Control components
• Protection method
• Certification

Without this information, an "explosion-proof crane" quotation may be based on assumptions and may not be acceptable to the EPC contractor or end user.

These terms should be clearly separated in a crane specification:

• CNEX – China's certification system for applicable explosion-protected products
• ATEX – European Union framework for equipment intended for potentially explosive atmospheres
• IECEx – International certification system based on IEC standards for equipment used in explosive atmospheres
• Ex d / Ex de / Ex t – These describe specific types of explosion protection, not alternative names for ATEX or IECEx

Therefore:
ATEX ≠ IECEx ≠ CNEX ≠ Ex d

What the buyer should do:
For an oil & gas or petrochemical project, provide the manufacturer with the project's hazardous-area classification and certification requirements before requesting the final quotation.

If the EPC specification states "IECEx certified equipment required," do not accept a quotation that simply says "Explosion-proof crane, CNEX." Ask the supplier to confirm whether the proposed equipment meets the specific IECEx requirement stated in the project specification.

Electrical specifications are another area where buyers should be precise. Common regional project requirements include:

• 380 V, 400 V, 415 V
• 50 Hz
• 3-phase

For example, if the customer's site power is 380 V / 50 Hz / 3 Ph, this should appear directly on the crane technical specification.

The buyer should also confirm:

• Control voltage
• Motor voltage
• VFD requirements
• IP protection
• Emergency stop
• Overload protection
• Limit switches
• Grounding
• Pendant or radio control
• Electrical cabinet location
• Cable system
• Main isolator requirements

Example: Do not write only "Power supply: 380 V." Write instead:

• Main power: 380 V, 50 Hz, 3 Ph
• Control: low-voltage control system
• Travel: VFD controlled
• Hoisting: VFD controlled where required
• Control: radio remote + pendant
• Electrical protection: according to project environmental requirements

This gives the manufacturer a much clearer electrical design basis.

When comparing quotations from Chinese, European, Russian/CIS, or other international crane manufacturers, do not compare price and tonnage alone.

Ask each supplier to provide the same technical information:

• Design standard
• Duty classification
• Crane structure (EOT or gantry)
• Hoist type
• Lifting attachment
• Motor specification
• Electrical components
• Environmental protection (low temp, dust, corrosion, seismic)
• Certification
• Testing
• Documentation
• Warranty

Then compare the quotations on the same technical basis.

A lower initial price may come from a lower duty classification, simpler electrical equipment, lower environmental protection, fewer documents, or a different testing scope. Conversely, a higher price is not automatically better unless the additional cost corresponds to a real project requirement.

For Central Asia and Caucasus industrial projects, Yuantai's approach is to use Chinese GB/T standards as the core engineering and manufacturing basis, then match the crane to the project's required CE, ISO, CNEX, GOST, electrical, environmental, seismic, inspection, and documentation requirements.

The best specification is therefore not the one with the longest list of standards. It is the one where the design basis, operating conditions, certifications, testing requirements, and deliverables are clearly defined before production starts.

Yuantai manufactures cranes in China and supplies them to industrial projects across Central Asia and the Caucasus.

A typical China-to-Central-Asia/Caucasus crane project follows a clear sequence:

Inquiry → Technical Specification → Crane Design → Drawing Approval → Manufacturing → FAT → Packing → Shipping → Installation → Commissioning

Stage-by-stage breakdown:

• 1. Inquiry – Buyer provides lifting and site requirements
• 2. Technical Specification – Capacity, span, lift, duty, power, and environment are confirmed
• 3. Crane Design – Supplier selects structure (EOT or gantry), hoist, attachment, motors, controls, and protection
• 4. Drawing Approval – GA drawings and technical documents are reviewed
• 5. Manufacturing – Crane components and structures are fabricated and assembled
• 6. FAT – Crane is tested and inspected before shipment
• 7. Packing – Equipment is prepared for rail/road/sea transportation
• 8. Shipping – Container, rail, or breakbulk transportation to the destination
• 9. Installation – Local contractor installs the crane and runway or gantry rail
• 10. Commissioning – Testing, adjustment, and operational handover

The most important point: Technical clarification should be completed before manufacturing starts. Changes to crane type, capacity, span, power supply, duty classification, control system, low-temperature requirements, seismic parameters, or environmental requirements after production begins can affect both cost and delivery.

The logistics method depends mainly on the crane dimensions, package weight, destination country, and shipping route. Most Central Asian markets are landlocked, which makes logistics planning more important than for coastal Middle East projects.

Logistics stages – what needs to be confirmed:

• China Factory – Final package dimensions, weights, and loading method
• Route Selection – Rail via Khorgos/Alashankou to Kazakhstan, or road/rail to Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan
• Caucasus Route – Sea to Poti/Batumi (Georgia) or Baku (Azerbaijan), then road/rail inland
• Container Shipment – Suitable for container-compatible components
• Breakbulk Shipment – May be used for large girders, gantry legs or oversized crane components
• Customs Documents – Invoice, packing list, B/L or rail waybill, certificate of origin, and other required documents
• Destination Handling – Port/rail terminal unloading and local cargo handling
• Inland Transportation – Delivery from terminal to the project site
• Installation – Local installation or customer-appointed contractor
• Commissioning – Supplier support according to the agreed scope

Common destination gateways:
Khorgos / Alashankou (China–Kazakhstan rail), Almaty (Kazakhstan), Tashkent (Uzbekistan), Baku (Azerbaijan), Poti / Batumi (Georgia), and Turkmenbashi (Turkmenistan, Caspian) – depending on the project location and shipping route.

Shipping time should not be presented as a fixed number for every project. It can change according to route, rail schedule, cargo size, shipping method, transshipment, border clearance, and customs conditions.

For this reason, the buyer should request a project-specific logistics quotation and estimated transit time after the final crane package dimensions and destination are confirmed.

Typical lead time: a configured EOT crane is usually delivered 60–90 days after drawing approval. Gantry cranes and ladle cranes, which involve more structural fabrication and testing, may require 90–120 days. Logistics transit time is additional and depends on the destination gateway.

For Central Asia and Caucasus industrial projects, Yuantai's role can extend beyond manufacturing the crane to supporting the complete supply process:

• Engineering – Custom crane design based on project requirements
• Documentation – GA drawings, calculations, electrical schematics, component lists, manuals, and certificates
• FAT – Factory Acceptance Testing before shipment, according to the approved Inspection and Test Plan
• Export Packing – Designed for rail/road/sea transportation and project handling – container or breakbulk
• Shipping Coordination – Support with logistics planning and documentation
• Commissioning Support – Technical assistance during installation and commissioning, according to the agreed scope
• Spare Parts – Recommended spare-parts lists and ongoing supply support

Key point: The supplier should be evaluated on the complete package – not just the crane itself. Documentation, testing, packing, shipping support, and after-sales service are equally important for a successful Central Asia or Caucasus project.

Yuantai manufactures overhead and gantry cranes in China and exports them to industrial projects across Central Asia and the Caucasus.

Before shipment, the crane can be inspected and tested according to the approved FAT procedure, applicable standards, and project requirements.

FAT items typically checked:

• Visual Inspection – Assembly, welding, painting, identification, and workmanship
• No-Load Test – Hoisting, trolley, and crane travel
• Rated-Load Test – Crane operation under rated load
• Hoisting Test – Hoisting/lowering, brake, and limit functions
• Cross-Travel Test – Trolley movement and control
• Long-Travel Test – Crane movement and braking
• Brake Test – Brake operation and load holding
• Limit-Switch Test – Hoisting and travel limits
• Electrical Test – Power, control, and protection functions
• Safety Test – Overload and other safety devices where applicable
• Overload Test – Only when required by the applicable standard or project specification
• Documentation Review – Test reports, certificates, and approved documents

Why FAT matters: FAT gives the EPC contractor, consultant, owner, or third-party inspector an opportunity to verify the crane before it leaves the factory. Any agreed corrections can be completed before packing and shipment – avoiding costly site modifications.

To prepare an accurate technical proposal, the crane supplier should receive at least the following project information:

• Crane type – EOT / gantry / explosion-proof
• Capacity – e.g., 50 ton
• Span or rail gauge – e.g., 22 m
• Lifting height – e.g., 12 m
• Runway or yard length – e.g., 100 m
• Load type – Hook / ladle / magnet / grab / container
• Operating hours – e.g., 16 h/day
• Lifting cycles – e.g., 10 cycles/hour
• Power supply – e.g., 380 V / 50 Hz / 3 Ph
• Installation – Indoor / outdoor
• Ambient temperature – e.g., –30°C to +40°C
• Environment – Dusty / coastal / corrosive
• Seismic zone – If applicable
• Hazardous area – If applicable (Zone, Gas Group, Temp Class)
• Control – Pendant / radio / cabin / PLC
• Project standard – Customer/EPC specification
• Inspection – FAT / third-party inspection

The more complete the project information, the more accurately Yuantai can determine the crane configuration, duty classification, motor and hoist selection, attachment, wheel loads, electrical system, environmental protection, seismic design, and project documentation.

For EPC projects, the recommended workflow is:

Technical Inquiry → Crane Design → GA & Load Data → Drawing Approval → Manufacturing → FAT → Final Documents → Shipping → Installation → Commissioning

Why this approach works:

• Helps identify building, electrical, seismic, wind and crane interface issues before manufacturing
• Reduces the risk of redesign, delays, and additional costs later in the project
• Ensures all stakeholders (owner, consultant, EPC, and installation contractor) are aligned on the crane design and site interfaces
• Provides a clear documentation trail for project approvals and quality control

Yuantai works with EPC contractors across Central Asia and the Caucasus on crane selection, engineering documentation, factory testing and export delivery.

Some Central Asia and Caucasus projects require inspection by an independent organization or a customer-appointed inspector before shipment.

Common inspection agencies:

• SGS – Third-party inspection and verification
• Bureau Veritas (BV) – Inspection and certification services
• TÜV – Testing, inspection, and certification
• Intertek – Inspection and testing
• Customer-Appointed Agency – Inspection according to owner/EPC requirements

Important: Third-party inspection is not automatically required for every crane order. It depends on the purchase contract, EPC specification, end-user requirements, financing conditions, or local project requirements.

What the buyer should do: State the inspection requirement clearly in the RFQ, for example:
"FAT by manufacturer + third-party inspection before shipment, according to approved ITP."

This allows the crane supplier to include the correct inspection scope, documentation, and schedule in the quotation.

Proper documentation planning is essential for a smooth crane delivery to Central Asia and the Caucasus. Here are best practices for buyers and EPC contractors:

• Agree the document list early – During the technical and commercial stage, not after manufacturing
• Specify certification requirements – CE, ATEX, IECEx, CNEX, GOST, or other project-specific certifications
• Clarify third-party inspection – State whether SGS, BV, TÜV, Intertek, or a customer-appointed agency is required
• Confirm language requirements – English is standard, but some projects may require Russian or local languages
• Request soft and hard copies – Electronic files for technical review, physical copies for customs and site handover
• Allow time for document review – Technical document approval can take time; factor this into the project schedule
• Confirm the logistics document set – Rail waybill vs. bill of lading, transit declarations, and border clearance documents for landlocked routes

By defining documentation requirements upfront, buyers can avoid:

• Customs and border clearance delays – Missing or incorrect shipping documents
• Technical approval rejections – Incomplete or non-compliant technical documents
• Project handover issues – Missing operation manuals, test reports, or certificates
• Additional costs – Rework, resubmission, or expedited document preparation

Yuantai prepares export and technical documents according to the purchase contract and project requirements, and supports customs and handover documentation for Central Asia and Caucasus deliveries.

Reliable. Customized. Compliant. Delivered on Time.

A mining concentrator maintenance bay normally needs a heavy-duty double girder EOT crane with an open winch hoist, typically in the 50–200 ton range. The crane lifts crusher shells, mill liners, pump bodies and motors, often on multiple shifts in a dusty environment with winter temperatures down to –40°C. The specification should include low-temperature steel, low-temp lubricants, IP55+ enclosures and a duty class calculated from the actual load spectrum. A standard workshop crane of the same capacity is not a substitute.

Only if the crane operates inside a classified hazardous area. A crane located in a non-classified maintenance workshop inside an oil and gas facility does not automatically require Ex configuration. The decision depends on the Zone, gas group and temperature class issued by the plant's process or safety engineering team. Ask for that document before requesting a quotation. Without it, the supplier cannot correctly determine the Ex equipment scope or the certification route (ATEX, IECEx or CNEX).

A configured EOT crane is usually delivered 60–90 days after drawing approval. Gantry cranes and ladle cranes, which involve more structural fabrication and testing, may require 90–120 days. Lead time starts from approved drawings, not from the initial inquiry. Logistics transit time is additional: rail to Kazakhstan via Khorgos or Alashankou, rail/road to Uzbekistan, and sea to Poti, Batumi or Baku for the Caucasus. Confirm the route and gateway before fixing a site date.

Because Georgian crane demand is concentrated in port container yards and open logistics terminals at Poti and Batumi, where there is no building structure to support an overhead crane runway. A rail-mounted gantry crane (RMG) or rubber-tyred gantry crane (RTG) spans the yard on its own legs and rails. Overhead cranes are still used in Georgia, but mainly inside the Rustavi steel and fertilizer plants and in maintenance workshops, not in the port yards.

Provide the seismic zone, the applicable design code, and the required seismic acceleration parameters for the site. Without these three items, the supplier cannot verify the crane, runway or gantry structure against seismic loads, and cannot supply the anti-derailment devices, buffer sizing or anchor design that the project may require. Seismic verification is mandatory for projects in Armenia and is routinely required in Uzbekistan, Georgia, Azerbaijan, Kyrgyzstan and Tajikistan.

Use a single girder crane for capacities up to about 20 tons, intermittent use, and standard workshop buildings where headroom is adequate. Use a double girder crane for capacities above 20 tons, continuous production, long spans, or where the hook must lift close to the roof. Most standard manufacturing workshops in Uzbek free economic zones are served by single or double girder cranes in the 5–50 ton range. Specifying a heavy-duty metallurgical crane for a standard workshop is over-specification and adds cost without benefit.

They differ by lifting attachment and process duty. A ladle crane lifts and pours molten metal ladles in a steelmaking bay and requires FEM M7–M8 duty, heat shielding and redundant braking. A magnet crane handles steel scrap, billets, plates and coils with an electromagnetic spreader. A grab crane handles bulk material such as cement clinker, coal, ore or fertilizer with a clamshell or orange-peel grab. A steel plant may need all three in different bays, plus a standard double girder crane for the maintenance workshop.

Yes, in many cases. A knock-down crane kit ships the hoist, end carriages, travel motors, gearboxes, control panel and electrical components, while the bridge girders are fabricated locally. This reduces freight volume, lowers import duties and leverages regional labor, often cutting total landed cost by 15–30%. It is most practical when the buyer has local fabrication and installation capability. Yuantai provides interface drawings, wheel load tables and bolt patterns to ensure the locally made girders fit the supplied components.

At minimum: GA drawing, wheel load data, crane reaction data, electrical drawings, component list, ITP, FAT report, load test report, operation and maintenance manuals, material certificates, and certificate of origin. If the project requires CE, ATEX, IECEx, CNEX or GOST documentation, list those separately in the RFQ. For landlocked routes, also confirm the rail waybill or bill of lading, transit declarations and border clearance documents. Agree the full document list during the technical and commercial stage, not after manufacturing.

Each adds cost, but in different ways. Low temperature (–30°C to –40°C) requires low-temperature impact-tested steel, low-temp lubricants, heated control cabinets and low-temp-rated cables. Dust requires IP55 or IP65 enclosures, sealed contactors and protected cable entries. Seismic design requires structural verification, anti-derailment devices, buffer sizing and anchor design. None of these are optional if the site conditions require them, but each should be priced separately so the buyer can see what is being paid for and compare quotations on the same technical basis.

They are different classification systems, not interchangeable labels. FEM (European) and ISO classifications describe crane duty based on load spectrum and operating frequency, using different notation (e.g., FEM M7 vs. ISO M7/A7). GOST is the CIS standard system and is commonly referenced in Kazakhstan and other CIS markets. A crane designed to one system is not automatically compliant with another. If the project specification names a standard, state it clearly in the RFQ and ask the supplier to confirm which standard applies to each part of the crane.

Yes, but the crane families differ by country. Kazakhstan needs heavy-duty EOT, ladle, magnet and grab cranes for mining and steel. Uzbekistan needs general-purpose EOT and grab cranes for manufacturing and building materials. Azerbaijan needs explosion-proof cranes for Caspian oil, gas and petrochemical facilities. Georgia needs gantry cranes for ports and logistics, plus general-purpose EOT for the Rustavi plants. A supplier that only offers one crane family will not fit all four markets. Check that the supplier's product range actually matches the country mix in your project.

The most useful first message contains five items: crane type or application, capacity, span (or gantry rail gauge), lifting height, and site location with its environment (indoor/outdoor, temperature range, dust, coastal, seismic, hazardous area if any). With these five, a supplier can give a preliminary configuration and a realistic price range. Without them, the quotation is a guess. Adding load spectrum and operating hours per day makes the quotation more precise and reduces the chance of a technical revision later.
