The double-girder design provides a larger working range and higher lifting capacity, allowing the gantry crane to handle heavier cargo and a larger working area. By optimizing the design of the traveling mechanism and the lifting mechanism, the double-girder gantry crane can achieve rapid cargo handling and positioning, thereby reducing operation time. The efficient electrical control system can ensure the precise operation of the gantry crane and reduce the waste of time and resources caused by operating errors. The double-girder structure provides additional stability and reduces safety accidents caused by structural instability. The legs and main beams of the gantry crane are usually made of high-strength steel to withstand the impact of heavy loads and harsh environments.
