The present invention provides a hydraulic lifting device, which includes: a lifting member lifting a heavy object by using a hydraulic pressure; a hydraulic pump supplying or releasing the hydraulic pressure with a steel member; and a hydraulic control valve which forms a fluid path connecting the lifting member and the hydraulic pump and connects one path and the other path of the fluid path arranged in parallel with each other to partially open and close the same in accordance with the applied hydraulic pressure so as to control a passage flow rate of the fluid so that the fluid flows with a constant hydraulic pressure through the fluid path.
본 발명은 유압을 이용하여 중량물을 승강시키는 승강부재, 승강부재로 유압을 공급하거나 해제하는 유압펌프 및 승강부재와 유압펌프 사이를 연결하는 유체통로를 형성하고, 인가되는 유압에 따라, 상호 평행하게 배치된 유체통로의 일측 통로 및 타측 통로를 연동하여 부분적으로 개폐함으로써, 유체통로를 통해 일정 유압으로 유체가 유동하도록 유체의 통과 유량을 조절하는 유압조절밸브를 포함하는 유압 리프팅 장치를 제공한다.
