The electric hoist semi-gantry crane is a small to medium-sized lifting device that operates on rails. It primarily consists of a gantry (main beam, outriggers, lower crossbeam, etc.), a hoisting mechanism, an operating mechanism, and an electronic control unit. The hoisting mechanism is an electric hoist that travels along the lower flange of the main beam’s I-beam. One side of the gantry is equipped with outriggers and operates along ground rails, while the other side, without outriggers, operates along rails above the factory building. The remaining structure and configuration are identical to the MH electric hoist gantry crane.
