How To Perform Maintenance And Upkeep Of The Boom Section Of A Concrete Pump Truck - Hunan Mecha Brothers Technology Co., Ltd.

To ensure the efficient operation of the 混凝土泵车 boom system and extend the service life of key components, it is recommended to lubricate and maintain the grease filling points of the boom, support legs, and chassis every 15 days to ensure that the moving parts such as the pin shaft and connecting rod maintain the best working condition.

Standardized operation process for butter filling

1.Site preparation: Choose an open and flat work site, support the concrete pump truck horizontally and firmly, fully deploy all booms to a horizontal extension state, and create safe and convenient operating conditions for lubrication operations.

2. Standardized oiling: Apply butter to each lubrication point of the arm frame in a step-by-step manner. When fresh butter is observed overflowing from the bearing area and the old oil is fully discharged, it indicates that the lubrication point has reached saturation and the next point operation can be carried out.

Key reminder: For lubrication points equipped with standard grease fittings (as shown in the figure below), it is necessary to strictly follow the filling cycle of once every 15 days to avoid lubrication failure.

Potential risk warning of lubrication deficiency

1. Efficiency loss: Insufficient lubrication will significantly increase the resistance of moving parts, causing abnormal friction noise and slow response of the boom, directly leading to a decrease in construction efficiency and delaying project progress.

2. Structural damage: Continuous lack of lubrication can accelerate the wear of the pin shaft and shaft sleeve, and in severe cases, may cause the pin shaft to break, leading to the failure of the boom structure and causing major safety accidents.

3. Fatigue failure: Stress concentration caused by poor lubrication in the hinge area can easily lead to metal fatigue, causing cracks or even fractures in key components, resulting in irreparable structural damage.

By strictly implementing the lubrication and maintenance system, the failure rate of concrete pump trucks can be effectively reduced, ensuring operational safety and achieving sustainable optimization of their performance.
