Weihua’s self-developed and self-manufactured 550-ton gantry crane has smoothly passed full load testing at a construction site in Guangdong. This heavy-duty model features a rated lifting capacity of 550 tons and a 10-metre trolley track span, setting a new maximum load record for Weihua’s double-girder U-shaped gantry cranes.

Core Technical Advantages

1.It is designed with dual 275-ton main hoisting units, capable of separate or combined operation. Built-in synchronous control ensures precise coordinated lifting and lowering during operation.

2.All operating systems are configured with frequency conversion and PLC intelligent control, enabling flexible speed adjustment under both full and light loads. The equipment runs steadily with mild impact and low operating noise.

3.Optimized lightweight design is adopted for the whole equipment. Finite element analysis is applied in steel structure design to guarantee reliable strength and rigidity. It features compact layout, light dead weight, low wheel pressure and outstanding energy-saving performance.

4.The travelling system is assembled with multi-stage balance beams and bogies. Huff hinge connection between bogies and balance beams ensures even stress distribution on all walking wheels for smoother travel.

For years, Weihua has taken technological innovation as the core driving force, constantly making breakthroughs in high-end, intelligent and eco-friendly core lifting technologies. Our reliable equipment has been widely applied in numerous national landmark projects, including Olympic venues, West-to-East Gas Transmission, South-to-North Water Diversion and Hangzhou Bay Bridge.

Looking ahead, Weihua will give full play to its industrial strength and resource edges, sticking to the development goals of globalization, digitalization, intellectualization and environmental friendliness. We will keep making strides to fuel steady and high-quality growth across the manufacturing sector.
