Double girder Gantry Crane consists of double main beam/girder structure and supporting legs, with Winch or Hoist running on the girders for lifting operation. The gantry crane supporting legs travels on rail track for material handling. The maximum tonnage of Eurocrane double girder gantry crane is 300 ton.It is widely used in factories, warehouses, stockyards, production workshops, and other occasions without brackets. Can be able to meet the requirementof material transportation without changing the structure of plant.
