The electric hoist semi portal crane

The electric hoist semi portal crane is a small and medium-sized lifting equipment with rail operation, which is mainly composed of portal frame (main beam, outrigger, lower beam, etc.), lifting mechanism, operating mechanism and electric control part. The electric hoist is used as the lifting mechanism, and runs along the lower flange of the I-beam of the main beam when working. One side of the gantry is equipped with outriggers, which run along the ground track, and the other side is not equipped with outriggers, which run along the upper track of the powerhouse. Other structures and configurations are the same as those of the MH electric hoist gantry crane.
