ABSTRACT:
A travelling gantry crane is mounted for movement along rails laid on the weather deck of a ship, but is adaptable for shore installations. Preferably two similar cranes are used in face-to-face arrangement and operable together as a unit for maximum lifting capacity, but they can be operated individually. Each travelling gantry crane has a pair of C-shaped leg members supporting between them a bridge girder, the leg members being movable by driven wheels. A shuttle girder is mounted for movement along the outward facing side of the bridge girder to provide for maximum outreach beyond the ends of the bridge girder. A load carrying trolley moves along the outward facing side of the shuttle girder remote from the bridge girder. The invention includes various detailed arrangements for moving the shuttle girder and the trolley, for securing the gantry crane on the rails, etc.
