Concrete pump truck is a kind of concrete machine which is often used in the construction project, it is usually used with concrete batching plant and concrete mixer truck. In order to ensure the normal operation, so not delay the construction project schedule, the operator is required to keep the inspection and maintenance before the construction even during construction. Here let us Haomei Machinery to tell you how to maintain the concrete pump truck.

The maintenance of the Concrete pump truck mainly including 8 steps, let us learn about them one by one.
1, Filled with grease, water tank added with 2/3 water and 1/3 hydraulic oil or oil..
2, Check the hydraulic oil level and oil quantity, the oil should be light yellow transparent, no emulsification or turbidity, or it should be replaced..
3, Check the distribution valve commutation, whether the stirrer device positive and negative action is normal..
4, Check the cutting ring, glasses board clearance should be normal (maximum gap of two millimeters)..
5, Check the hydraulic system whether there is oil spills or oil leakage phenomenon..
6, Check all the threaded connection to ensure the solid connection..
7, Check the lubrication system work status, the progressive dispenser indicator rod back and forth action should be seen, there are oil overflow in lubrication points such as S pipe arm end bearing position, stirring shaft bearing position and so on. Manual lubrication points should be filled with grease each work class..
8, Due to the load bearing during operation, after a period of time, due to local stress concentration, oxidation and corrosion of local structural parts, it may occur cracks. So the users must do weld inspection on the boom and other structural parts every 300 hours work.
