Concrete pump truck boom is the most important component, as the support structure, the strength and performance of the boom without the pump pipe also determines the importance of the concrete pump truck, however, in the daily work, the process of pumping concrete will produce a strong impact on the boom so, during construction, the boom of a small concrete pump truck will produce a certain degree of shaking, which is not good for the boom, because the shaking, the boom will be subjected to various deformation forces, which will lead to the boom steel fatigue deformation, which makes the small concrete pump truck boom cracking, and even serious safety accidents, therefore, in the daily use of concrete pump truck, the maintenance of the boom is very important.

  1. As the entire concrete pump truck mount is installed above the chassis, the connection between the top and the chassis needs to be checked irregularly to ensure that the two are firm.

  2. Check the concrete pump truck turntable, that is, between the boom and the connecting parts of the concrete pump truck, mainly check whether the connecting pin shaft, rotating gear, etc. are seriously worn, check whether the bolts are loose and abnormal, and whether the fatigue cracking phenomenon of the material exists in the joint part.

  3. Check boom cylinder, balance valve, tubing and so on whether oil leakage, whether the tubing interference components. As the power source of the whole boom, oil leakage and other factors will affect the whole boom rise and fall, which is usually manifested in the boom can not work properly.
