EOT Crane Middle East | Industrial Projects & Solutions

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

Engineered for steel mills, mining, cement plants, shipyards, and petrochemical refineries. The double girder overhead crane price is significantly influenced by wheel load calculations, VFD drives (standard on all motions), 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.

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 (since runway columns are eliminated), 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 (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. Yuantai offers full documentation packages for local authority approval (e.g., SASO, ADNOC, Qatargas). Price also varies with temperature class (T1–T6) and gas group – the more severe the zone, the more rigorous (and expensive) 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%.

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 large steel fabricators across the GCC.

Two cranes with the same rated capacity can have completely different price tags. Here are the top factors:

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 – IP55, IP65, C5 corrosion coating, heat-resistant paint.
⑧ Hazardous area certification – ATEX/IECEx 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).

Heavy-duty EOT cranes are found in virtually every heavy industry sector. Below are the key industries, typical lifting work, and crane requirements that define each application:

• Steel Plants – Billets, coils, plates, beams, production equipment – Heavy-duty double girder, open winch, VFD, special lifting devices
• Steel Fabrication – H-beams, vessels, structures, fabricated assemblies – Long-span design, smooth travel, radio remote/cabin
• Cement Plants – Motors, gearboxes, crushers, process equipment – Heavy-duty mechanisms, dust protection, maintenance access
• Mining – Mining machinery, crushers, conveyors, processing equipment – High-duty operation, robust mechanical components, dust protection
• Petrochemical Plants – Pumps, vessels, compressors, process equipment – Heavy-duty EOT / process crane; Ex configuration where required
• Heavy Machinery Manufacturing – Machine tools, engines, dies, large components – High positioning accuracy, VFD, lifting beams
• Shipyards – Engines, ship components, steel structures – Large capacity, long span, corrosion protection
• EPC Projects – Process equipment, structural components, plant machinery – Customized engineering, documentation, FAT and inspection

Whether it's a UAE petrochemical workshop or an Oman mining facility, the crane requirements must be matched to the actual load, environment, and operational rhythm – not just a generic specification.

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 Middle East 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 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
• 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 high ambient temperatures (up to 55°C)
• Runway structure – Crane wheel loads must be checked against the building/runway design
• Control system – Radio, cabin, PLC and synchronization can be added according to process requirements

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

Yuantai heavy-duty EOT cranes can be engineered with a wide range of advanced features to match the specific demands of Middle East steel, cement, mining, and petrochemical 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
• 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, magnets or grabs – 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 Middle East 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 takeaway: A 50-ton open-winch crane may be the right choice for a continuous 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 – Saudi 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 2 – UAE Petrochemical Workshop
Capacity: 80 ton  |  Span: 22 m  |  Lifting height: 10 m
Load: Pumps, compressors and process equipment
Operation: Maintenance lifting  |  Environment: Classified hazardous area

The buyer must provide the hazardous-area classification before the explosion-protection system is selected. The crane may require an ATEX/IECEx-certified configuration, but the exact Ex specification should come from the project's hazardous-area requirements.

Example 3 – Oman Mining Facility
Capacity: 100 ton  |  Span: 28 m  |  Lifting height: 15 m
Operation: Multiple shifts  |  Environment: High dust

In this case, the design must consider not only the 100-ton SWL but also dust protection, 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.

Yuantai supplies customized heavy-duty EOT 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 Middle East projects, particular attention is given to:

• High ambient temperature – Motor insulation, oil viscosity, cooling
• Desert dust – IP ratings, enclosure protection, maintenance intervals
• Coastal corrosion – C5 or marine-grade corrosion protection
• Hazardous areas – ATEX/IECEx certification, Zone, Gas Group, Temperature Class
• Long-span buildings – Structural integration and runway design
• Multi-shift operation – High-duty components and redundant systems
• High utilization – FEM/ISO duty classification based on actual load spectrum

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

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

Before selecting an explosion-proof crane, the buyer must provide the hazardous-area information issued by the plant's electrical, process, or safety engineering team. Do not ask the crane manufacturer to guess the classification.

Key information required:

• Hazard type – Gas/vapor or combustible dust (e.g., flammable gas)
• Zone classification – Hazardous area zone (e.g., Zone 1)
• Gas group – Substance classification (e.g., IIA, IIB, IIC)
• Temperature class – Maximum surface-temperature requirement (e.g., T4)
• Protection concept – Required Ex protection method (e.g., Ex d, Ex de)
• Ambient temperature – Maximum/minimum site temperature (e.g., up to 50–55°C)
• Installation – Indoor, outdoor, or partially enclosed
• Corrosive environment – Salt, chemicals, humidity (e.g., coastal petrochemical site)
• Power supply – Site electrical system (e.g., 415 V / 50 Hz / 3 Ph)
• Certification – Required project certification (e.g., ATEX, IECEx, CNEX)

Useful RFQ example:
"80 ton EOT crane, 20 m span, 10 m lift, Zone 1, Gas Group IIB, T4, indoor petrochemical workshop, 415 V / 50 Hz / 3 Ph."

This gives the crane manufacturer substantially more information than simply writing "80 ton explosion-proof crane."

These terms are not interchangeable. Each represents a specific regulatory framework, certification system, or protection concept that must be matched to the hazardous area, gas/dust group, temperature class, and equipment category.

• ATEX – European regulatory framework for equipment used in potentially explosive atmospheres. Commonly specified for projects requiring European conformity.
• IECEx – International certification system for Ex equipment. Frequently used on international oil & gas projects.
• Ex d – Flameproof enclosure protection concept. Equipment enclosure is designed to contain an internal explosion and prevent ignition transmission.
• Ex de – Combination involving flameproof and increased-safety protection. Applied according to the equipment's certified design.
• Ex t – Protection by enclosure for combustible dust atmospheres. Used for applicable dust-hazard environments.
• CNEX – Chinese explosion-protection certification system. Can be required for equipment certified for the Chinese market or specified by the project.

For a Middle East project, the buyer must specify whether the EPC contractor, end user, consultant, or local authority requires ATEX, IECEx, CNEX, or another specific certification route.

Yuantai can configure explosion-protected EOT cranes around different bridge and hoisting arrangements, depending on the capacity, duty, and hazardous-area requirements.

• Explosion-Proof Single Girder EOT Crane – Lower-capacity hazardous-area workshops. Compact and economical for suitable loads.
• Explosion-Proof Double Girder EOT Crane – Higher-capacity and heavier-duty applications. Higher structural capacity and suitable for heavy loads. For cranes above 20 tons, this is generally the starting point.
• Explosion-Proof Wire Rope Hoist – General hazardous-area lifting. Integrated hoisting solution.
• European Explosion-Proof Hoist – Compact industrial workshops. Low headroom and smooth operation.
• Explosion-Proof Pendant Control – Local operator control where the project allows pendant operation.
• Explosion-Proof Radio Control – Large workshops or areas requiring better operator visibility.
• Explosion-Proof Cabin Operation – Large or process cranes where dedicated visibility and control are required.

The final arrangement depends on the actual load, span, duty classification, lifting height, building structure, and hazardous-area requirements – not a one-size-fits-all approach.

An explosion-proof crane is not created simply by adding an Ex label to the hoist. The relevant electrical and control equipment must be selected according to the certified system.

Components that may require Ex protection:

• Hoisting motor – Explosion-protected motor where required
• Travel motors – Ex-rated travel motors where required
• Hoist brake – Suitable certified/protected brake arrangement
• Electrical control panel – Appropriate Ex enclosure/protection
• Pendant control – Explosion-protected pendant where required
• Radio control – Ex-certified radio system where specified
• Limit switches – Suitable Ex-rated devices
• Cable glands – Appropriate certified cable-entry system
• Junction boxes – Suitable Ex protection
• Sensors – Ex-rated sensors where installed in the hazardous zone
• Lighting – Ex lighting where part of the crane system and required
• Heating devices – Suitable certified Ex heating equipment where applicable

Critical note: Installing a certified Ex motor does not automatically make the entire crane suitable for a hazardous area. The complete equipment selection must be reviewed as a system.

Middle East projects often combine hazardous atmospheres with high temperature, desert dust, humidity, and coastal corrosion. These conditions must be considered together during the crane engineering process.

• High ambient temperature – Check Ex equipment temperature rating and motor thermal performance (critical in Saudi, UAE, Qatar, Kuwait)
• Desert dust – Appropriate enclosure protection and protected electrical equipment (critical in all GCC countries)
• Coastal salt air – Corrosion-resistant coating and suitable hardware (critical in UAE, Qatar, Kuwait, Eastern Saudi)
• High humidity – Electrical insulation and anti-condensation measures where required
• Outdoor installation – Weather-resistant electrical and mechanical protection
• Continuous operation – Correct duty classification and thermal calculations

Real-world examples:
Qatar LNG facility – Requires both hazardous-area certification and enhanced corrosion protection due to coastal environment.
Saudi petrochemical plant – Requires particular attention to high ambient temperature, dust, hazardous-area classification, and multi-shift operation.
UAE coastal oil & gas workshop – Requires a combination of Ex equipment, corrosion protection, appropriate enclosure protection, and temperature-rated components.

For an accurate explosion-proof EOT crane quotation, the following project data is highly recommended:

• Crane capacity – e.g., 50 ton
• Span – e.g., 22 m
• Lifting height – e.g., 12 m
• Crane travel – e.g., 80 m
• Load – Pumps, compressors, process equipment, etc.
• Duty – e.g., 2 shifts/day
• Lifting cycles – e.g., 10 cycles/hour
• Installation – Indoor / outdoor
• Ambient temperature – e.g., 50°C
• Hazardous area – e.g., Zone 1
• Gas group – e.g., IIB
• Temperature class – e.g., T4
• Protection concept – e.g., Ex d / Ex de as specified
• Power supply – e.g., 415 V / 50 Hz / 3 Ph
• Control – Ex pendant / Ex radio / cabin
• Certification – ATEX / IECEx / CNEX / project requirement
• Coating – C4/C5 where required
• Inspection – FAT / third-party inspection

The hazardous-area classification is particularly important. Without it, the supplier may be unable to correctly determine the required Ex equipment and certification scope.

For Middle East oil & gas and petrochemical projects, Yuantai supports the process from technical clarification and crane configuration through engineering, manufacturing, FAT, documentation, export packing, and commissioning support.

Engineering process:

Hazardous-Area Data → Crane Duty → Mechanical Design → Ex Electrical Design → Certification Requirements → Drawing Approval → Manufacturing → FAT → Export

The goal is not simply to supply an "explosion-proof crane." The objective is to provide a crane whose capacity, duty, mechanical structure, electrical equipment, Ex protection, environmental protection, and certification documentation all match the actual project requirements.

For the RFQ, the most important information is:
Capacity + span + lifting height + duty + load type + hazardous-area classification + gas/dust group + temperature class + ambient temperature + power supply + required certification.

High summer temperatures can affect motors, brakes, VFDs, control cabinets, cables, lubricants, and electrical components. If a project specifies an ambient temperature approaching 50–55°C, this value must be included in the crane technical specification before equipment is selected.

Engineering measures for high-temperature environments:

• 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 – Ventilation, heat dissipation or cooling where required
• Brake – Thermal capacity checked for lifting cycle and ambient conditions
• Gearbox – Lubricant and thermal performance at expected temperature
• Cables – Temperature rating appropriate to installation
• Insulation – Motor insulation system suitable for operating temperature
• Lubricants – Suitable viscosity and temperature range
• Electrical components – Manufacturer's allowable ambient temperature verified

Buyer example: A specification stating "Ambient temperature: 55°C" is more useful than simply "20-ton EOT crane, 20 m span." However, the buyer should also provide installation location, operating hours, and lifting cycles.

Best RFQ example:
"20 ton / 20 m span / 10 m lift / 55°C ambient / 10 cycles per hour / 16 h per day"

Important: 55°C ambient temperature does not automatically mean every crane component must be rated to 55°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 desert or dusty industrial 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

IP Protection – What should the buyer specify?
The buyer should not simply write "IP65 required" without explaining the installation conditions. The appropriate enclosure protection depends on dust, water exposure, heat dissipation, maintenance requirements, and equipment location.

Examples by installation type:

• Indoor workshop – Provide dust level and ventilation details
• Outdoor crane – Provide dust + rain + UV + 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
• Coastal industrial plant – Provide dust + humidity + salt exposure details

For an outdoor crane, the RFQ should clearly state whether the equipment is exposed to wind-blown sand, rain, direct sunlight, and large temperature fluctuations.

Cranes installed near ports, shipyards, coastal factories, desalination facilities, petrochemical plants, and marine logistics areas can experience humidity and salt-air exposure. This is particularly relevant to parts of the UAE, Qatar, Oman, and coastal Saudi Arabia.

Corrosion protection should be considered for the entire crane – 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

The coating system should be selected according to the corrosivity category, exposure level, expected service life, and project coating specification. A crane several kilometers inland should not automatically receive the same corrosion system as a crane installed directly beside a marine terminal.

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

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, steel 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., steel 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
• Heavy-duty wire rope hoists
• Open-winch hoisting mechanisms – Preferred for very high capacities and process cranes
• 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 steel products 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 – Girder design and wheel loads
• Lifting height – Drum, rope and hoist arrangement
• Load type – Hook, C-hook, 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
• Dust – Enclosure and equipment protection
• Coastal exposure – Coating and corrosion protection
• Hazardous area – Ex equipment and certification
• Power supply – Motors, VFDs and electrical system
• Control method – Pendant, radio, cabin or PLC
• Building structure – Runway and wheel-load requirements
• Installation conditions – Crane dimensions and maintenance access

This is why Yuantai approaches Middle East 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.
• Quotation changes later – Critical information such as 55°C ambient temperature, hazardous-area classification, 415 V power supply, or 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 → define the electrical system → then select the crane configuration.

For Middle East industrial projects, this approach provides a more reliable basis for selecting the EOT crane structure, hoist, motors, brakes, electrical protection, control system, corrosion protection, and duty classification.

Yuantai – Your Trusted EOT Crane Manufacturer for the Middle East
Reliable. Customized. Compliant. Delivered on Time.

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

• 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: up to 50°C
• Power supply: 415 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.

Middle East projects may also refer to ISO, FEM, DIN, IEC, EN, CMAA, 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.

Practical approach – establish a design basis document:

• Crane structure – Yuantai: GB/T standards | Project may require: ISO / FEM / DIN / 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 / customer standard
• Motors – Yuantai: Chinese standards | Project may require: IEC / 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 / 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 an EOT 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 UAE 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 oil refineries, petrochemical plants, LNG facilities, gas processing, chemical plants, oil & gas workshops, and hazardous maintenance areas.

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: 50°C
• Power supply: 415 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 Middle East project requirements include:

• 380 V, 400 V, 415 V, 440 V, 460 V
• 50 Hz or 60 Hz
• 3-phase

For example, if the customer's site power is 415 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: 415 V." Write instead:

• Main power: 415 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, 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
• Hoist type
• Motor specification
• Electrical components
• Environmental protection
• 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 Middle East 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, electrical, environmental, 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.

A typical China-to-Middle-East 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, hoist, 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 sea transportation
• 8. Shipping – Container or breakbulk transportation to the destination port
• 9. Installation – Local contractor installs the crane and runway equipment
• 10. Commissioning – Testing, adjustment, and operational handover

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

The logistics method depends mainly on the crane dimensions, package weight, destination port, and shipping route.

Logistics stages – what needs to be confirmed:

• China Factory – Final package dimensions, weights, and loading method
• Port Selection – Suitable Chinese export port based on cargo and shipping route
• Container Shipment – Suitable for container-compatible components
• Breakbulk Shipment – May be used for large girders or oversized crane components
• Port Delivery – Cargo delivered to the selected Middle East port
• Customs Documents – Invoice, packing list, B/L, certificate of origin, and other required documents
• Destination Handling – Port unloading and local cargo handling
• Inland Transportation – Delivery from port to the project site
• Installation – Local installation or customer-appointed contractor
• Commissioning – Supplier support according to the agreed scope

Common Middle East destination ports:
Jebel Ali (UAE), Dammam (Saudi Arabia), Jeddah (Saudi Arabia), Hamad Port (Qatar), Sohar (Oman), and Salalah (Oman) – 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 port, vessel schedule, cargo size, shipping method, transshipment, and customs conditions.

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

For Middle East 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 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 takeaway: 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 Middle East project.

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:

• Capacity – e.g., 50 ton
• Span – e.g., 22 m
• Lifting height – e.g., 12 m
• Runway length – e.g., 100 m
• Load type – Steel / machinery / vessel
• Operating hours – e.g., 16 h/day
• Lifting cycles – e.g., 10 cycles/hour
• Power supply – e.g., 415 V / 50 Hz / 3 Ph
• Installation – Indoor / outdoor
• Ambient temperature – e.g., 50°C
• Environment – Dusty / coastal / corrosive
• 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, wheel loads, electrical system, environmental protection, 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, 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

Some Middle East 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 the Middle East. 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, 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 Arabic or other 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

By defining documentation requirements upfront, buyers can avoid:

• Customs 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
