Weihua's 550-ton gantry crane successfully completed the load test.
The 550 ton gantry crane independently developed and produced by Weihua successfully completed the load test at the project site in Guangdong, China.
The lifting capacity of the whole gantry crane is 550t, and the trolley gauge is 10m.
1. The main hoisting mechanism adopts 275+275t double lifting points, which can work alone or at the same time. Equipped with synchronous control function, it can realize simultaneous lifting and lowering.
2. Each mechanism adopts frequency conversion + PLC control to realize slow running at full load and fast running at light load, stable lifting and running, small impact and low noise.
3. The whole crane adopts lightweight design, and the steel structure adopts finite element analysis design, which meets the requirements of strength and stiffness, compact structure, light weight, small wheel pressure and low energy consumption.
4. The traveling mechanism of the crane adopts a combined structure of a multi-stage balance beam and a trolley, and the trolley and the balance beam are connected by a Huff hinge to ensure that the wheels are evenly stressed.
