This single girder semi gantry crane is mainly composed of electric hoist, single main beam, legs, electrical equipment, etc. One end beam runs on the elevated runway beam, and the other end beam runs on the ground track, which saves production space and cost. The semi gantry crane leg has a height difference, which can be determined according to the site conditions. The special reducer for the lower beam can make the working space inside the crane larger.
