In the working process of the excavator, sometimes it is necessary to force the flame out, such as failure, emergency, repair and maintenance. So how should the excavator be forced to shut down? Below we introduce several common methods of forced extinguishing of excavator.

First, manual extinguishing method

Manual flameout method is the most common method, only need to operate a few simple steps to successfully flameout. The specific steps are as follows:

1. Close all levers: Before turning off the engine, place all levers in a neutral position and open the handbrake.

2. Turn OFF the engine: manually turn the key of the excavator from the “ON” position to the “off” position, and then turn off the power.

Note: When manually flameout, it is necessary to ensure that all electrical equipment is turned off, so as to ensure that the excavator is completely flameout and there will be no safety hazards.

Second, oil cut-off power method

Oil cut-off method is also an effective extinguishing method. It forces the engine to stop running by cutting off fuel and power. The specific operation method is as follows:

1. Cut off the fuel: open the engine hatch, find the fuel system, and cut off all the fuel lines of the fuel pump, filter, and fuel solenoid valve.

2. Cut off the power supply: Find the power supply system, remove the positive and negative power plugs of the battery, and cut off the power supply.

Note: The operation steps of the oil cut-off method are relatively complicated, and it also involves some mechanical and electrical knowledge. If you are not familiar with the operation, you need to follow the manufacturer’s operating specifications.

Third, emergency parking law

This method is usually only used when there is an emergency, such as an accident of the excavator, unexpected conditions, etc. The specific operation method is as follows:

1. Emergency stop signal: Press the emergency stop button, pay attention to the emergency stop button is generally more visible, can be easily operated in the cab.

2. Wait for extinguishing: After pressing the emergency stop signal, the excavator will automatically enter the parking state, and soon cut off the power supply, and the safety equipment will automatically open, waiting for the excavator to be completely extinguished.

Note: The emergency stop button is the forced extinguishing button of the excavator, which can quickly cut off the power and prevent the expansion of the accident.

In short, there are many ways for the excavator to force flame out, and different methods also involve different operating steps and precautions. Therefore, before the forced extinguishing of the excavator, it is necessary to carefully learn to master the corresponding operation methods, so as to ensure the safety and smooth operation.
