　　这是由于行走电机的负载溢出阀芯卡住造成的。为了维护管理系统的，在管理系统中设置了两个负载溢流阀。如果一个负荷溢流阀的阀芯卡在溢流的特定位置，则会使管理系统的工作压力损失。

　　This is caused by the stuck load overflow valve element of the traveling motor. In order to maintain the safety of the management system, two load relief valves are set in the management system. If the valve core of a load relief valve is stuck in the specific position of the overflow, the working pressure of the management system will be lost.
