The present invention relates to a ship crane for supporting the lifting and lowering of a ship, which is installed on a mother ship and is connected to a main wire rope that is pulled out or wound from a main winch mounted on a main body, so as to be able to lift or lower a ship. A sub-winch unit is further provided, which is able to lift or lower a ship together with the main wire rope by pulling out or winding the first and second sub-wire ropes downward through sub-rods extended on both sides along a direction intersecting the transport direction of the main wire rope on the main body. According to this ship crane for supporting the lifting and lowering of a ship, the first and second sub-wire ropes are driven to generate a set supporting force together with the main wire rope when the ship is raised or lowered, thereby providing an advantage in that the raising and lowering operation can be performed more stably in a three-point support state.

    본 발명은 모선에 설치되며 메인바디에 장착된 메인 윈취로부터 인출 또는 감기는 메인 와이어로프에 결합하여 자선을 인양 또는 하강할 수 있도록 된 자선 인양 및 하강 지원용 선박 크레인에 관한 것으로서, 메인바디에 메인 와이어로프의 이송방향과 교차하는 방향을 따라 양측으로 연장된 서브 로드를 통해 제1 및 제2서브 와이어로프를 하방으로 인출 또는 감아 자선을 메인 와이어로프와 함께 3점 지지상태로 인양 또는 하강할 수 있도록 된 서브 윈치유니트를 더 구비한다. 이러한 자선 인양 및 하강 지원용 선박 크레인에 의하면, 자선의 승하강시 메인와이어로프와 함께 제1 및 제2서브와이어로프가 설정된 버팀력을 생성하도록 구동됨으로써 3점 지지상태로 보다 안정적으로 승하강 작업이 이루어질 수 있는 장점을 제공한다.
