Abstract

The invention discloses a variable-amplitude crane for rescue boats and life rafts. The variable-amplitude crane comprises a base, a swing mechanism, a power mechanism, a lifting mechanism and an electric control box. The lifting mechanism comprises a tower, an electric winch, a variable-amplitude oil cylinder, a crane jib and a hook. The electric winch comprises a motor, a reel and a brake. A pulley is arranged at the top end of the crane jib. A wire rope wound around the reel is connected to the hook through the pulley. A remote-control swing cable and a remote-control dropping cable are arranged at the front end of the crane jib. One end of the variable-amplitude oil cylinder is connected with the tower, and the other end of the variable-amplitude oil cylinder is connected with the middle portion of the crane jib. The variable-amplitude crane has the advantages that the variable-amplitude structure is combined with a hydraulic swing bearing, the crane jib can conveniently change thelifting height and the swing angle, and the working area is large, so that the rescue boats or the life rafts can be placed at heights of hull decks to make full use of the hull space, and safety andreliability during escape are improved correspondingly.

Description

technical field [0001] The invention relates to a crane, in particular to a variable amplitude rescue boat and liferaft crane which can make full use of deck space. Background technique [0002] The International Convention for the Safety of Life at Sea has stipulated that cargo ships and passenger ships must be equipped with rescue boats or life rafts, and the rescue boat and life raft cranes are special cranes installed on board and used in conjunction with rescue boats and life rafts. Send the escaped people into the rescue boat and life raft and hoist them on the water surface. The common rescue boat and life raft cranes are all fixed-arm type. The rescue boat and life raft are suspended on the crane and located on the side of the ship. Although the structure is simple , easy to operate, but the crane, rescue boat and life raft take up a lot of space, occupying the deck and aisle, and the escape personnel are vulnerable to the collision and extrusion of the rescue boat a...
