IMPROVEMENTS RELATING TO THE HANDLING OF A SUBMERSIBLE FROM A MOTHER SHIP

摘要

In order to facilitate the handling of a submersible from a mother ship and avoid manual operations in the water there is provided a lift hook assembly for a submersible, the assembly comprising a hook (1), a latch (2) for the hook (1), the latch (2) being in the form of a bell-crank pivotally mounted at (3) on the hook (1) for movement between a first position where one arm (4) of the bell-crank forms a cradle alongside the opening of the hook (1) and the other arm (7) blocks the hook (1), and a second position where the one arm (4) closes the hook (1), and the other arm (7) unblocks the hook (1). Means for actuating the latch (2) are provided in the form of an air cylinder (8), and a throat (10) is provided for guiding a soft eye of a lift line onto the cradle. An opening (13) through the one arm (4) is provided for the passage therethrough of a haul-down line (14), and a pulley (15) is provided for guiding the haul-down line (14) so that the soft eye can be pulled by the haul-down line (14) through the throat (10) and onto the cradle.
