500 Ton High Performance Double Girder Shipbuilding Grantry Crane

Shipbuilding Gantry CraneProduct DescriptionShipbuilding gantry crane is a kind of great lifting capacity, large span, high lifting altitude, multi function, high efficiency of gantry crane, is special for the fragmented transport, end-to-end joint and turning operation of large ship hulls. ME shipbuilding gantry crane is used in the place of manufacturing of ship and dock. With the development of large-scale shipbuilding, Shipyard gantry crane for sale , shipbuilding gantry crane is the rapid growth of demand. Compared with the traditional portal crane, large shipbuilding gantry crane has the obvious advantage of the installation and transportation of hull sections. It spans the dock (berth), can provide on-site assembly service at the coverage plane in the dock, not only has the lifting, horizontal transport function, but also can implement hull air turnover, adjusting the fragment to the welding position of ship required.Technology Parameters  Please contact me for customized parameters !Shipping Building Gantry Crane Main SpecificationLifting capacity2x25t+100t2x75t+100t2x100t+160t2x150t+200t2x400t+400tTotal Lifting capacityt1502003005001000Turning over capacityt100150200300800Spanm507038.5175185Lifting HeightAbove rail35502865/1076/13Below rail35502865/1076/13Max.
