Detection and use of old construction machinery to delay the aging of equipment

After being used for a period of time, bulldozers, loaders, excavators and truck cranes often experience a decline in the sensitivity of the operating mechanism and slow movement of the working mechanism.

"1 Phenomenon

The engine exhaust, operation and sound are all abnormal. It is difficult to start and the acceleration is slow. The oil in the hydraulic system is contaminated. The external and internal oil leakage of hydraulic components, pipelines and joints is severe. The hydraulic cylinder cannot be locked and automatically retracts. The transmission chains of all the control handles of the entire machine are loose, causing obstruction and difficulty during operation.

2 Reasons

The main issues are prolonged overwork and operating in environments that do not meet the requirements. Daily maintenance is not timely, and major, medium and minor repairs fail to meet the standard requirements.

3 Measures

(1) Strictly manage and continuously improve the technical quality of operators to ensure the correct use of construction machinery.

(2) Strengthen the daily maintenance and inspection of equipment to improve its integrity rate.

(3) Enhance the technical proficiency and sense of responsibility of maintenance personnel to ensure the quality of major, medium and minor repairs. Appropriately increase dedicated maintenance equipment, tools, instruments and technical data.

(4) Adjust and repair the machinery
