Single girder gantry crane is also called electric single girder gantry crane, single main girder gantry crane or electric hoist gantry crane. Single girder gantry crane is used in conjunction with CD, MD and other types of electric hoists. It is a rail-running gantry crane.
Box girder:
The steel plate is welded into a box-type structure, which has the characteristics of high safety and high rigidity. Generally used for large tonnage and super tonnage gantry cranes. As shown in the overview picture MGhz1200, with a lifting capacity of 1200 tons, is the largest gantry crane in China, and the main beam adopts a box girder structure. Box girder also has the disadvantages of high cost, heavy self-weight and poor wind resistance.
