The electric hoist semi-gantry crane is a small and medium-sized hoisting equipment that runs on rails. It mainly consists of a mast (main beam, outriggers, lower beams, etc.), a hoisting mechanism, an operating mechanism, and an electric control part. The electric hoist is used as a hoist. The lifting mechanism runs along the lower flange of the I-beam of the main beam when working. There are outriggers on one side of the mast, which runs along the ground track, and the other side has no outriggers, and runs along the track on the upper part of the plant. The rest of the structure and configuration are the same as the MH electric hoist gantry crane.
