Abstract:
There is disclosed a travelling crane arrangement for a floating vessel having a pair of substantially parallel tracks. The crane arrangement comprises: a pair of uprights (18) for movement on respective said tracks and a transverse beam (16) extending between said uprights so as to extend across a deck of the vessel in spaced relation thereto. The beam has a trolley (24,25) arranged for movement along the beam and the trolley carries at least part of a lifting mechanism which is operable to lift a load above the deck. The crane arrangement is characterised by the provision of a support (92,93) selectively positionable in a brace position in which it extends between the deck and the trolley to at least partially support the beam in compression during use of the crane to lift or otherwise support the weight of a load.
