    摘要： A boat lift (10) for use with a boat (40) and an ocean structure (20) is provided, wherein the lift (10) includes one or more mechanisms (100, 120) for raising the boat (40) in respect of the structure (20) and/or for lowering the boat (40) in respect of the structure (20). The one or more mechanisms (100, 120) are mounted to the boat (40), and the one or more mechanisms (100, 120) are adapted to engage onto one or more upright members (130) of the structure (20). Each mechanism (100, 120) includes a configuration of at least two rollers (120A, 120B) for engaging onto the one or more upright members (130), the at least two rollers (120, 120B) being adapted to be forced in operation into engagement onto the one or more upright members (130) by a weight of the boat (40) acting upon the at least two rollers (120A, 120B). The lift (10) further includes lifting actuators (140) operable to rotate one or more of the rollers (120A, 120B). The structure (20) includes one or more of: a portion of an oil rig, a hull of a cargo vessel, a base of a tower of a large offshore wind turbine, a central floating platform of an ocean wave energy park, a passenger ship.

    摘要： The apparatus including a hook 12 pivoted on pin 16 below its hooking point 20 between a pair of plates 14, and having a cam locking structure 32, 30. The force applied to the hook by the pull of the item being held causes the cam surfaces to jam and keep the hook closed but, when the force applied to the hook falls below a predetermined value, a counterweight 70 rotates the cam structure 56 away from the hook and allows opening rotation (anticlockwise) of the hook. The counterweight is further used to positively pull the hook to the open position after a given amount of travel via a lanyard 80, 24. Additionally a locking pin structure 74 may be provided to prevent the automatic disengagement occurring and a spring-biased reset via lanyard 28 may also be provided.
