The present invention provides an automatic leveling system of horizontality for an assistance device mounted in an end portion of a boom through a derrick cylinder and a slave cylinder, which is provided with a derrick cylinder having a function to erect or lower a boom and another function to automatically adjust horizontality of an assistance device by communicating with a slave cylinder to prevent damage to a conventional master cylinder. Moreover, a structure of an end portion of the boom and a turntable is simplified to provide great appearance and significantly reduce manufacturing costs and maintenance costs.

    본 발명은 붐을 기립시키거나 하강시키는 기능과, 슬레이브실린더와 연동되어 보조장치의 수평을 자동으로 조절하는 기능을 갖는 데릭실린더를 구비하여 기존의 마스터실린더의 파손으로 인해 발생하는 다양한 문제점을 해결할 수 있으며, 붐의 단부와 턴테이블의 구조가 단순해짐에 따라 외관상 보기 좋고 제조단가와 유지, 보수 비용을 현저히 절감할 수 있는 데릭실린더와 슬레이브실린더를 통한 붐의 단부에 장착되는 보조장치의 수평 자동레벨링 시스템을 개시한다.
