Abstract
The present invention has been developed to improve the way a payload support platform, such as a mole, is driven between one site and another, particularly when the second site is the interior of a Lift which interfaces with a Pallet Handling System (PHS) of a ship. In a first aspect the invention proposes that the driving means which drives the payload support platform along a rail (10) is also used to move that rail (10) relative to the payload support platform and a support rail (22) so that the position of the rail can be changed during the movement of the payload support platform between one site and another. The payload support platform is lockable to the support rail (22), such that the force which drives the payload support platform along the rail (10) changes to driving the rail (10) relative to the support rail (22). In a second independent aspect of the invention the movable rail (10) is mounted in the gap between ends of fixed rails (62, 82) and is movable along a support rail (22) on which it is mounted between a position in which one end of the movable rail (10) is adjacent an end of one of the fixed rails (62, 82) to another position in which the other end of the movable rail (10) is adjacent the end of the other fixed rail (62,82).
