An underwater shackle for heavy loads is described, comprising a shackle body (10) equipped with respective side plates (12a, 12b) and an upper, intermediate suspension (14) for connection to a lifting, strap, a lifting cable or the like, and also a lower locking bolt (20) for connection to the load. The locking bolt (20) is arranged to a hydraulically driven cylinder arrangement (30) so that it can move, where the cylinder arrangement (30) is placed adjoining one of the side plates (12a) and the cylinder arrangement (30) is arranged to be pressurized by a pressure medium to move the locking bolt (20) between a withdrawn position in the cylinder arrangement (30) and a locking position in the shackle body (10). A pressure distributor (40) is arranged with the cylinder arrangement (30) to receive and distribute the pressure medium, where the pressure distributor (40) comprises supply channels (44, 4) that run together with the first and the second inlet channels (34, 36) in the cylinder arrangement (30). |

1. Underwater shackle for heavy loads, comprising a shackle body (10) equipped with respective side plates (12a, 12b) and an upper, intermediate suspension (14) for connection to a lifting strap, a lifting cable, and also a lower locking bolt (20) for connection to the load,
the locking bolt (20) is movable arranged in a hydraulically driven cylinder arrangement (30), where the cylinder arrangement (30) is placed adjoining one of the side plates (12a) and where the cylinder arrangement (30) is arranged to be pressurised by a pressure medium to move the locking, bolt (20) between a withdrawn position in the cylinder arrangement (30) and a locking position in the shackle body (10), the cylinder arrangement (30) comprises an inner cylinder boring (32), where a piston part (22) of the locking bolt (20) is arranged for longitudinal movement in the boring, and a first inlet channel (34) for supply of the pressure medium to a first side of the piston part (22), arranged for an outgoing, movement of the locking bolt (20) from the cylinder arrangement (30) and also a second inlet channel (36) for supply of the pressure medium to the other side of the piston part (22), arranged for ingoing movement of the locking bolt (20) into the cylinder arrangement (30), wherein a pressure distributor (40) to receive and distribute the pressure medium is arranged to the cylinder arrangement (30), were the pressure distributor (40) comprises supply channels (44,46) that run together with said first and second inlet, channels (34,36) in the cylinder arrangement (30). |
