Semi gantry crane are a cost-effective alternative which just have one side support leg, the other leg traveling on the ground rail, the other side is the end of the bridge girder same as the overhead crane end beam, it is traveling on the bracket rail. They are also an ideal supplement to overhead/bridge cranes at the workstation level.
The advantage of semi gantry crane is that it can be installed below overhead cranes that already exist. That realized the extensive cover of the floor area. Semi gantry crane is mainly used in Steel, Forest Products, Intermodal, Biomass/Pellet, Concrete and many other industries.
