Hydraulic Control Device FOR CONSTRUCTION MACHINERY
본 발명은 건설기계의 유압제어시스템에 관한 것으로서, 건설기계의 작업장치를 승강 구동시키는 실린더; 작업레버의 조작에 따라 상기 실린더에 공급되는 압유의 흐름을 제어하는 컨트롤밸브; 상기 컨트롤밸브에 압유를 공급하는 유압펌프; 및 상기 작업장치의 작동 중 자중에 의해서 동작되는 작업에서 작동되며, 유압탱크로 복귀되는 압유의 배압을 선택적으로 가변하여 상기 실린더의 작동에 재이용하는 압유재생부를 포함하는 것을 특징으로 한다.
The present invention relates to a hydraulic control system for a construction machine, which is characterized by comprising: a cylinder driving up and down a work apparatus of a construction machine; a control valve controlling the flow of pressure oil supplied to the cylinder corresponding to the manipulation of a work lever; a hydraulic pump supplying the pressure oil to the control valve; and a pressure oil regenerating unit operated in a process which is performed by a dead weight during the operation of the work apparatus, and selectively varies back pressure of the pressure oil recovered to the hydraulic tank in order to reuse the same for the operation of the cylinder.
