Maintenance and Repair of Excavators in Rainy Season(Part 2)

Common faults in the rainy season

The most common failures for excavators during rainy season construction are the engine cannot start and the vehicle does not move.

1. The engine cannot be started. It may be that the battery voltage is not enough, whether the ECV is supplying power, whether the ignition switch is invalid, whether the speed sensor is transmitting normally, etc. The main things that can be urgently determined on the spot are whether the battery voltage is normal, whether the insurance is burned out, etc.

2. The whole vehicle does not move. The problem caused is more complicated, but you can quickly check on the spot whether the safety operating lever is pulled up, whether the coil of the safety solenoid valve is damaged, whether the insurance is burned, and troubleshooting.

Precautions for construction in the rainy season

1. Pay attention to the surrounding environment before construction, and check whether the construction site is soft and the vehicle is stuck. The general method is: use a bamboo pole to poke down manually. If multiple bamboo poles are slammed down quickly without any effort, and there is no resistance within 1 meter, it means that the place is all silt, and ordinary excavators are very easy to get stuck and cannot perform normal construction.

2. Before construction in the rainy season in mountainous areas, first observe whether there is a possibility of landslides, landslides, and debris flows on the mountain. First observe whether the mountain is broken, whether there is unreasonable excavation, unreasonable spoil, spoil, and quarrying, whether the vegetation is growing well, and whether the mountain is turbid.

3. During the construction process, if you feel that the excavator has begun to sink, stop the construction in time and find a support point to support the car body with a big arm to prevent further sinking. Hurry up and drive the excavator to return on the original road, and do not drive in other directions.

4. Always be vigilant when working in the rain. During night work, the front and rear headlights, work lights, top lights, instrument lights, wipers, etc. of the excavator should be kept in normal operation to ensure safety.

5. After the construction is over, the excavator must be parked in a safe area close to the residential area on higher ground, far away from possible landslides, the river rises, and other dangerous areas and the excavator must have sufficient oil to start evacuation at any time.
