Why does the excavator suddenly stop moving?
1 Answers
The following are the reasons why the excavator suddenly stops moving: Reasons for the excavator not moving: insufficient hydraulic oil in the tank, main pump suction empty; suction filter clogged. Engine coupling damaged (such as winch, elastic disc, etc.); main pump failure; servo system pressure too low or no pressure; safety valve setting pressure too low or stuck; main pump suction pipe burst or detached. Inspection: Check if the excavator pilot pressure is normal. If abnormal, check if the pilot filter is clogged or damaged. If damaged, it will cause low pressure. In addition, severe wear of the internal gears of the pilot pump can also cause internal leakage, making it impossible to establish working pressure.
