MH type electric hoist gantry crane is a single girder box type gantry crane with electric hoist as the lifting mechanism. It can be divided into truss type and box type. The lifting capacity is generally less than 32 tons. I will introduce the technical parameters of the 5-ton electric hoist gantry crane.
