The present invention relates to a cabin for a crawler crane, and more particularly to a cabin installed on the body of a crawler crane which is configured to be rotatable at an angle of 90 degrees so that when the crawler crane is disassembled and moved to a site of use, the cabin, which is installed to project outwardly from the body of the crane, can be rotated 90 degrees inwardly from the body of the crane. In other words, the present invention provides a cabin installed on the body of a crawler crane, and the body and the cabin are joined by rotating means so that the cabin can be rotated so that it protrudes outwardly from the body and the field of vision can be obtained when the crawler crane is used in the field, and when the crawler crane is disassembled and moved, the main boom is disconnected and rotated into a space reserved so that there is no part protruding outwardly from the body. The rotating means includes: an axle support portion integrally formed in the cabin; a rotating shaft coupled to the axle support portion; a drive gearbox comprising a worm wheel coupled to the rotating shaft and a worm driving the worm wheel; and a reverse-driveable hydraulic motor mounted in the body with the drive gearbox to drive the worm wheel and the worm.

    본 발명은 크롤러 크레인의 캐빈에 관한 것으로, 보다 구체적으로는 차체에 설치되는 캐빈을 90도 각도로 회전 가능하도록 구성하여 크롤러 크레인을 분해한 상태로 사용처로 이동할 때 차체의 바깥쪽으로 돌출되도록 설치되어 있는 캐빈을 차체 안쪽으로 90도 회동시킬 수 있도록 한 것이다. 즉, 본 발명은 크롤러 크레인의 차체에 캐빈을 설치함에 있어서; 상기 차체와 캐빈은 회동수단으로 결합하여 현장에서 사용할 때는 차체의 바깥쪽으로 돌출되도록 회전시켜 시야 확보가 이루어질 수 있도록 하고, 분해하여 이동시에는 메인 붐이 분리되어 확보된 공간으로 회동시켜 차체의 외부로 돌출된 부분이 없도록 하며; 상기 회동수단은, 캐빈에 일체 형성한 축지부와; 상기 축지부에 결합되는 회동축과; 상기 회동축에 결합된 웜휠 및 웜휠을 구동시키는 웜을 포함하는 구동기어박스와; 상기 웜휠을 웜을 구동하도록 구동기어박스와 함께 차체에 설치한 정역구동 가능한 유압모터를 포함하도록 한 것이다.
