The gantry crane (also known as the gantry crane) is a bridge-type crane whose bridge is supported on ground rails by legs on both sides. Structurally, it consists of a gantry frame, large crane running mechanism, lifting trolley, and electrical components. Some gantry cranes have legs on only one side, while the other side runs on a support in a factory building or trestle bridge, known as a semi-gantry crane. The gantry frame of the gantry crane is composed of the upper bridge (including the main beam and end beams), legs, lower crossbeam, and other parts. To expand the operating range of the crane, the main beam can extend beyond the legs on one or both sides, forming an arm. It is also possible to use a lifting trolley with a jib, expanding the crane's operating range through the pitching and rotation of the jib.
