The present invention relates to a self-contained winch for an LNG marine vessel which provides rotation power to a lifter winding a rope or a chain, comprising: a main motor generating rotation force by hydraulic pressure; a pumping unit of a closed loop method by communicating with the main motor to forcibly pump hydraulic oil; a power unit for generating rotation power source of the lifter by hydraulic pressure of the hydraulic oil supplied by the pumping unit; a gearbox transferring the rotation power of the power unit to the lifter; a cooler for cooling the hydraulic oil in an air cooling method via an interior portion thereof; and a control portion for controlling motion of the pumping unit.

    본 발명은 로프 또는 체인을 권취하는 리프터에 회전동력을 제공하는 LNG 선박용 자급형 윈치에 있어서, 유압에 의해 회전력을 발생하는 메인모터와, 상기 메인모터와 연동하여 유압유를 강제 펌핑하는 폐유로(Closed-loop)방식의 펌핑유닛과, 상기 펌핑유닛에서 제공받은 유압유의 유압에 의해 리프터의 회전 동력원을 생산하는 동력유닛과, 상기 동력유닛의 회전 동력을 리프터에 전달하는 기어박스와, 상기 유압유를 내부로 경유시켜 공냉방식으로 냉각하는 냉각기와, 상기 펌핑유닛의 동작을 제어하기 위한 제어부를 포함하여 구성됨을 특징으로 한다.
