How to maintain the shock absorber of the garbage truck
Shock absorption is to provide a buffer for the garbage truck when driving on bumpy roads, and it can also improve the smoothness and comfort of the garbage truck. Therefore, the quality of the shock absorber will directly affect the operation of the garbage truck, so how do we maintain it?
1. Stop the garbage truck after driving 10km on the road with poor road conditions. Touch the shock absorber shell with your hands. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work. At this time, you can add appropriate lubricating oil, and then test, if the shell heats up, there is a lack of oil inside the shock absorber, and enough oil should be added, otherwise the shock absorber has failed.
2. Press the bumper firmly and then release it. If the garbage truck jumps 2 or 3 times, it means that the shock absorber of the garbage truck is working well.
3. When the garbage truck is driving slowly and brakes urgently, if the garbage truck vibrates violently, it means there is a problem with the shock absorber.
4. Remove the shock absorber of the garbage truck and stand it upright, and clamp the lower connecting ring on the vise, and then forcefully pull the damping rod several times. At this time, there should be stable resistance, and the resistance of pulling upwards should be greater than downwards. The resistance during compression, such as unstable or no resistance, may be due to lack of oil inside the shock absorber or damage to the valve parts. Repair or replacement of parts should be carried out.
After determining that the shock absorber of the garbage truck is defective or invalid, you should first check whether the shock absorber leaks or has traces of old oil leakage. The oil seal washer and sealing washer are broken and damaged, and the oil storage cylinder head nut is loose. It may be that the oil seal and sealing gasket are damaged and invalid. Replace with new seals.
