Semi gantry crane compared with electric single-girder crane, save investment and space, compared with electric hoist gantry crane, save the production space, therefore when selecting ordinary electric single-girder crane or electric hoist gantry crane is not very ideal, semi gantry crane is a better solution.

1, Semi gantry crane structure: by the lifting mechanism and the trolley, single girder and leg, electric cabinet, operating system and safety protection system, etc;

2. Semi gantry crane drive: squirrel-cage motor + machine of decelerate of hard tooth flank, disc brakes, free maintenance;

3. Semi gantry crane operation mode: the cable to hold (IP65, life 500000 times), wireless remote control, driving operation
