Independently researched, developed and manufactured by Weihua, this 550-ton gantry crane has successfully passed full load testing at a construction site in Guangdong, China. With a rated lifting capacity of 550 tons and a trolley track gauge of 10 meters, this equipment sets a new internal tonnage record for Weihua’s U-type double girder gantry crane series.
Dual 275-ton lifting point system
The main lifting system adopts dual 275-ton lifting points, supporting both independent and synchronous operation. Equipped with synchronized control logic, the two lifting units can complete hoisting and lowering actions simultaneously with high coordination, ensuring stable and precise heavy-load handling.
Variable frequency and PLC integrated control
All operating mechanisms adopt variable frequency and PLC integrated control technology. The system enables flexible switching between fast and slow speed operation under full-load and light-load conditions, delivering stable lifting and travelling performance with minimal mechanical impact and low operating noise.
Lightweight optimized structural design
The whole machine adopts an optimized lightweight design. Finite element analysis is applied for steel structure calculation to meet standard strength and rigidity requirements. The compact structural layout effectively reduces self-weight and wheel pressure, achieving lower energy consumption during long-term operation.
Multi-stage balance beam travelling mechanism
The crane travelling mechanism adopts a combined structure of multi-stage balance beams and wheel bogies. Huff hinge connections between bogies and balance beams ensure even force distribution on each walking wheel, providing smoother, safer and more reliable travelling performance.
