The present invention provides a lifting device capable of overcoming a limit of a stroke of a hydraulic cylinder and lifting a heavy object to a high place. The lifting device includes: a driving cylinder (30) fixed by a foundation structure (91) and moving a moving pulley (20) so that the moving pulley (20) approaches and is separated from a fixed pulley (10) as a cylinder rod (31) is connected to the moving pulley (20); and a lifting wire (40) installed by being wound on the fixed pulley (10) and the moving pulley (20) while one end of the lifting wire (40) is fixed to the foundation structure (91) and the other end is connected to a workpiece (50). The workpiece (50) ascends and descends since the moving pulley (20) approaches or is separated from the fixed pulley (10).

    본 발명은 유압실린더의 스트로크의 한계를 극복하고 중량물을 높은 장소까지 리프팅 할 수 있도록 한 리프팅장치를 제공한다. 본 발명은 기초구조물(91)에 의해 위치가 고정되고 실린더로드(31)가 이동도르레(20)에 결합되어 이동도르레(20)를 고정도르레(10)에 접근 및 이격운동시키는 구동실린더(30)와, 일단이 기초구조물(91)에 의해 고정되고 타단이 작업물(50)에 결합된 상태에서 고정도르레(10)와 이동도르레(20)를 감아 돌아 설치된 리프팅와이어(40)를 포함하여, 상기 이동도르레(20)가 고정도르레(10)에 접근 및 이격됨에 의해 작업물(50)이 하강 및 상승한다.
