5 Ton Overhead Cranes Without Main Girder for UAE Warehouses

Customer Background

A well-known multinational logistics company in Dubai, UAE, operating a modern high-bay warehouse within the Jebel Ali Free Zone, dedicated to providing storage and distribution services for high-end consumer goods and precision instruments. The warehouse features a high internal clear height and dense racking, where traditional column-supported cranes severely restricted the storage layout and material-handling flexibility.

Core Pain Points:

• Low Space Utilization: Existing equipment columns occupied valuable floor space, limiting rack layout and preventing increased storage density.
• Inefficient Material Handling: Old cranes operated unstably with imprecise positioning, posing risks when handling high-value goods and failing to meet rapid inbound/outbound demands.
• Poor Flexibility: Inability to adapt to changing operational zones or temporary large-item handling tasks.

Yuantai Crane Kits Solution

Yuantai Crane custom-designed and exported a fleet of 5 ton overhead cranes (without main girder) to create a comprehensive and flexible handling system. The technical specifications were as follows:



Model: European-style design, overhead crane without main girder

Quantity & Configuration:

7 units – 5 ton capacity, 20 meters span, 9 meters lifting height
1 unit – 5 ton capacity, 10 meters span, 9 meters lifting height

Power Supply: 440V / 50Hz / 3Phase, tailored for the local grid.

Core Hoisting Mechanism: Equipped with European-style wire rope hoists, featuring dual-speed motors (0.8 m/min micro-speed / 5 m/min normal speed) for seamless switching between precision assembly and rapid handling.

Travel Control: Both bridge and trolley travel utilize variable frequency drive (VFD) speed control, with a speed range of 2-20 m/min, ensuring smooth, shock-free operation from start to stop and millimeter-level positioning accuracy.

Safety & Intelligence: Standard overload protection, limit switches, anti-collision systems (for coordinated operation between multiple cranes), and compatibility with warehouse intelligent management systems.

What Our Girderless Overhead Crane System Includes

Our solution is a fully integrated system, typically comprising:
 

1. Runway System: High-precision steel rails and necessary supports designed for your building's structure.
2. End Carriages (Traveling Wheels): Robust units housing motors, brakes, and wheels for smooth bridge travel along the runway.
3. Hoist & Trolley Assembly: The specified European-style wire rope hoist is mounted on a trolley for transverse movement.
4. Electrical Control System: Including VFD panels, push-button pendant station (or radio remote control), and all safety sensors.
5. All Connecting Components & Safety Devices: Festooning or conductor bar for power supply, limit switches, buffers, and warning devices.

Implementation Results

• Space Revolution & System Coverage: The deployment of eight cranes, particularly the seven 20-meter-span units, provided extensive coverage across the warehouse floor, eliminating ground-level obstacles. This strategic layout resulted in an immediate 18% increase in effective storage area and operational flexibility.
• Precision Operation: The 0.8 m/min micro-speed enabled safe and precise placement of high-value, fragile goods across all eight cranes.
• High-Speed Flow & Synchronization: The 5 m/min normal hoisting speed combined with 2-20 m/min variable frequency travel allowed multiple cranes to operate simultaneously without interference, reducing average workflow cycle time by over 30%.
• Smooth & Reliable: VFD control eliminated load sway on every unit, significantly reducing cargo positioning time and greatly enhancing operator confidence and safety in a multi-crane environment.
• Operational Cost Optimization: The standardized European design across the fleet simplified training, maintenance, and spare parts management. The lightweight structures reduced building load, and the energy-efficient VFD systems lowered overall power consumption, reducing total lifecycle costs.

Intelligent Overhead Crane Solutions to Update UAE Business
