Do not panic when the boom of the concrete pump truck is abnormal. In fact, the sound of the boom of the concrete pump truck is the lack of lubricating oil that leads to friction between the booms, which will lead to the reduction of the flexibility of the boom and the damage of the boom in the long term. Therefore, maintenance is also the best way to increase the life of the concrete pump truck.
1. Use the lubricating oil gun to drive the lubricating oil into the oil nozzle of the boom. Each section of the boom has a lubricating oil nozzle, which shall prevail when the lubricating oil spills.
2. Run the boom after it is done, and let the lubricating oil lubricate the joint of the boom.
