MG120t - 32m - 22m Double Beam Gantry Crane For Steel Factory / Port / Shipbuilding

MG120t - 32m - 22m Double Beam Gantry Crane

MG double girder Electric Goliath Gantry Cranes for precast beam field offer an economical solution to overhead cranes when the building is unable to support a bridge crane or the crane system is to be placed outdoors. Box girder gantry crane is a gantry crane that utilizes the "box" type when fabricate the girder. This box girder design incorporates a four-sided box with a running surface plate, so that the hoist trolley can be attached. The advantage of the box girder finds expression in greater loading capabilities and greater bridge distances. The crane is generally utilized in pairs with the hoisting mechanism operating on rails attached to the top of each box girder.

MG gantry portal crane with winch trolley can be applied to both single girder and double girder format. It is ideal for outdoor applications where lifting devices can be applied without the cost of supporting steelwork. Indoor applications are also available where with a low ceiling and overhead cranes are not suitable. Typical occasions of goliath gantry crane include steel stock yards, loading areas, the concrete industry, ship building, and workshops.
