Four-leg construction machine with slope stabilization system with locking valve
A machine includes a first ground engaging unit connected to a first leg, a second ground engaging unit connected to a second leg, and a hydraulic system to control the height of the legs, the hydraulic system including a fluid circuit to control fluid between the first leg and the second leg; a load holding valve allowing fluid to enter the fluid circuit; a control valve system for introducing fluid into the load holding valve, the control valve being connected to the hydraulic fluid source and the reservoir; a first lock valve controlling a flow of fluid in a first direction between the first leg and the second leg; a second lock valve controlling a flow of fluid in a second direction between the second leg and the first leg; and first and second floating valves configured to connect the first and second legs to the control valve system, respectively.
一种机械包括连接到第一腿部的第一地面接合单元、连接到第二腿部的第二地面接合单元，以及控制腿部的高度的液压系统，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；允许流体进入流体回路的负载保持阀；使流体进入负载保持阀的控制阀系统，控制阀连接到液压流体源和储集器；控制流体沿第一方向在第一腿部与第二腿部之间的流动的第一锁定阀；控制流体沿第二方向在第二腿部与第一腿部之间的流动的第二锁定阀；以及配置成将第一腿部和第二腿部分别连接到控制阀系统的第一浮动阀和第二浮动阀。
