The end delivery pipe of the pump truck, also known as the concrete pump truck hose, is suitable for connecting the end of the construction machinery pump truck during concrete transportation, and can flexibly change the pouring position for small-scale concrete paving. There are many direct selling concrete wear-resistant hose manufacturers in China.

The construction of concrete pump trucks often achieves continuous pouring for a certain period of time, with a long duration and uninterrupted operation. If a malfunction occurs, it will affect the construction progress of the user, bring negative impacts on the economic and social benefits of both parties, so it must be diagnosed and eliminated in a timely manner.

For example, during the construction process of a pump truck, there may be abnormal noise from the boom. The possible causes and solutions are as follows, hoping to provide inspiration and assistance to those who see it.

1) Poor lubrication.

Suggestion for handling: Check the lubrication condition of various abnormal noises.

2) The symmetry error between the turntable and the hydraulic cylinder seat of the boom is too large, resulting in friction on the end face.

Suggestion for handling: Check the contact surface between the turntable and the arm frame. If there is severe friction, it needs to be repaired or replaced.

3) Friction between the connecting rod and the arm frame, as well as between the connecting rod and the end face of the hydraulic cylinder seat caused by symmetry errors.

Suggestion for handling: Check the contact surfaces between the boom, connecting rod, and hydraulic cylinder. If there is severe friction, it needs to be repaired or replaced.
