Single girder gantry crane is simple in structure and convenient in production and manufacture

The gantry crane with single main beam is simple in structure, convenient in production, manufacturing and assembly, small in quality, and most load-bearing beams are box-shaped steel frame structures. Compared with the double - stack beam gantry crane, the overall bending stiffness is weaker. Therefore, when the lifting weight Q≤ 50T and span S≤35m, this …
