Large-tonnage shipbuilding gantry crane with maintenance hoist
Large-tonnage shipbuilding gantry crane with maintenance hoist is a kind of lifting equipment with large span, large lifting capacity,
multifunction and high efficiency, specialized in section transport, docking and turnover of hull in shipyard or slipway.
Large-tonnage shipbuilding gantry crane with maintenance hoist mainly consists of main girder, rigid leg, flexible leg, upper and
lower trolley, maintenance jib crane, crane travelling mechanism and electrical control.
Large-tonnage shipbuilding gantry crane achieves the turnover of hull through the cooperation of two trolleys. First, upper trolley
bear the whole weight of hull through the adjustment of the position of hook(Fig.1), and lower trolley pass under the upper trolley.
The hook is retied to another side of hull(Fig.2). Second, upper one will give up the hook, and Upper and lower one go on reverse
running and then finish the turnover of hull(Fig.3).
