The MBH-type electric hoist semi-gantry crane is designed to work with CD, MD, HC and other types of electric hoists. It is a rail-mounted medium- and small-sized lifting device. The crane consists of the gantry frame (main beam, leg, lower crossbeam, etc.), hoisting mechanism, traveling mechanism, and electrical system. The electric hoist serves as the lifting mechanism and travels along the lower flange of the I-beam on the main beam.

One side of the gantry is equipped with a support leg that runs on the ground rail, while the other side has no leg and operates on the elevated runway of the workshop. All other structures and configurations are consistent with those of the MH-type electric hoist gantry crane.
