Analysis of the reasons why the excavator suddenly shuts down and then turns on again while working

Many problems often occur when a small excavator is working. For example, it suddenly shuts down while working, and then restarts again. What is the reason? What are the reasons that the editor here analyzes for you?

1. Hydraulic system failure

Hydraulic system failure is one of the main reasons for excavator stalling. When there is a problem with the hydraulic system, the excavator may automatically shut down due to lack of relevant hydraulic pressure. The cause of hydraulic system failure may be air leakage in the system, low pressure or abnormal pump, etc. To solve this problem, you can check the pressure of the hydraulic system and the operation of the pump, and replace the hydraulic oil and filter in time.

2. Electrical system failure

Electrical system failure is another possible cause of excavator stalling. If the battery power is low or the wiring fails, the electrical system may short-circuit and cause the excavator to automatically shut down. To avoid this, you can check the battery's charge, check whether the wires are normal, and see if the connectors are in good contact. If you cannot solve it by yourself, it is recommended to contact professional technicians for assistance in time.

3. Fuel system failure

Another common cause of excavator stalling is fuel system failure. Poor fuel quality, a clogged air filter, insufficient engine oil, and more can cause fuel system problems. To solve this problem, the fuel filter and air filter should be replaced regularly, and the engine oil should be ensured.

4. Other reasons

There are other reasons why the excavator stalls, such as driver error, internal damage and wear of the machine, etc. For driver operating errors, it is recommended to strengthen operational training. Internal damage and wear to the machine may require replacement of parts. In this case, technicians can perform necessary maintenance work on the excavator to ensure the normal operation of the machine.

In short, when encountering a situation where the excavator suddenly stalls and then turns on, you must calmly analyze the cause of the problem and take appropriate measures for maintenance and repair in a timely manner. This can ensure the normal operation of the excavator and effectively avoid production efficiency and safety problems.
