Four-leg construction machine with slope stabilization system with pressure relief valve
A machine includes a frame, a plurality of ground engaging units, a plurality of movable legs, and a hydraulic system. A first ground engaging unit and a second ground engaging unit connect the first leg and the second leg with the frame, respectively. The hydraulic system controls the height of the plurality of movable legs. The hydraulic system includes a fluid circuit that controls fluid between the first leg and the second leg, a load holding valve that controls fluid flowing into the fluid circuit, and first and second pressure relief valves that control fluid flow between the first leg and the second leg in opposite directions. A method for controlling a slope of a construction machine includes activating a pressure relief valve connecting a right lift cylinder and a left lift cylinder to control flow of hydraulic fluid between the lift cylinders to control retraction of one of the lift cylinders from retraction.
一种机械包括框架、多个地面接合单元、多个可移动腿部和液压系统。第一地面接合单元和第二地面接合单元分别将第一腿部和第二腿部与框架连接。液压系统控制多个可移动腿部的高度。液压系统包括控制第一腿部与第二腿部之间的流体的流体回路、控制流入流体回路中的流体的负载保持阀、以及控制流体沿相反方向在第一腿部与第二腿部之间的流动的第一减压阀和第二减压阀。一种用于控制施工机械的斜率的方法包括激活连接右提升缸和左提升缸的减压阀以控制液压流体在提升缸之间的流动，以控制提升缸中的一个提升缸的缩回以免缩回。
