Double Girder Gantry Crane

The double girder gantry crane from Zhonggong has been extensively used for materials handling in outdoor warehouses, storage yards, railway freight depots, shipyards, ports, etc. It can be equipped with special lifting tools for special lifting works. For instance, the double girder crane can use hooks and grab buckets to realize handling of different materials.

This shipbuilding gantry crane mainly consists of girder, cabin, legs, crane travel mechanism, trolley hoist and electrical equipment. It comes with outstanding robustness due to welded box girder and stable movement due to separate drive of crane travel mechanism. All operations of the port crane are completed in the driver cabin.
