Shipbuilding gantry crane steel structure compose of gantry frame, electric hoist or winch trolley, travel mechanism, and electrical devices, is totally strictly design and manufacture according GB/T8504-95 technical standard, GB/T1440693 gantry crane, GB6067 safety reputation, GB3811-2008 design standard.
Shipbuilding Gantry Crane is used in the place of manufacturing of ship and dock, with the development of large-scale shipbuilding, Shipbuilding Gantry Crane demand rapidly grow. Compared with the traditional portal crane, shipbuilding gantry crane has the obvious advantage of the installation and transportation of hull sections, 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.
