What Is Double Girder Gantry Crane?
The double girder gantry crane is heavy duty gantry crane with two dual main beam/girder structure. Components of double girder gantry crane is mainly consisted of girder bridge, support legs, winch trolley, crane travelling mechanism, and electric system. Electric winch / wire rope hoist runs on the girders for lifting operation. The gantry crane travels on rail tracks to different positions for material handling. At the two ends of the main beam, there can be outstretched cantilevers for a larger working range. And can be equipped with a variety of spreaders (hook type, grabs, electromagnets, C-hooks, etc.) for operation.
