Railway Engineering Hook Lifting Gantry Crane could be designed as single beam gantry crane or double beam gantry crane. The main application of gantry crane for railway construction is lifting the bridge beams. Railway company engineering Beam lifting gantry crane can be lifting the prefabricated beam with 2 cranes together, can also be a single crane with a double lifting hook for lifting the prefabricated beam, two lifting at the same time lifting the beam from the general weight of 450 tons, a single lifting from the beam machine The weight is usually up to 900 tons. It is equipped with walking legs, crane bridge and crane lifting equipment, you can achieve all-round mechanized action. It is mainly used to lift the prefabricated beam from the beam platform to the beam table. After the maintenance of the prefabricated beam is completed, it will be lifted from the beam to the beam truck. As the beam lifting gantry crane equipment could complete the bridge machine assembly and disassembly. But also for the construction of the pier dry bridge.
