Excavator W4-60C legs in the use of the following problems often occur: ① leg in the support operation automatically retracted, the so-called soft leg phenomenon; ② legs in the stool under its own weight after sinking slowly; ③ leg retractable action slow. This article will analyze the problems caused by leg cylinder and hydraulic lock leakage. 1 working principle Figure 1 is a simplified diagram of the working principle of the legs.
