What are the contents of regular maintenance of construction machinery?

Construction machinery is an indispensable mechanical product in modern engineering construction. However, due to its high strength, it needs regular maintenance. However, construction machinery also has a certain degree of regular maintenance. Generally, according to the maintenance requirements of various mechanical equipment, after reaching the specified working hours or mileage, corresponding regular maintenance must be carried out. Maintenance level mainly includes the following aspects:

1, main maintenance:

The first-level maintenance work is carried out on the basis of routine maintenance, and the key work contents are lubrication, fastening and inspection of all related components, as well as cleaning the "three filters" (that is, cleaning air, oil and fuel filters, etc. ). The first-level maintenance is guided by the mechanical team leader and completed by the mechanical operator.

2. Secondary maintenance:

Secondary maintenance focuses on inspection and adjustment. Specifically, it is necessary to check the working conditions of the engine, clutch, transmission, transmission mechanism, steering and braking mechanism, working device, hydraulic system and electrical system and make necessary adjustments to eliminate the faults found and ensure the good working performance of all mechanical assemblies and parts. Secondary maintenance shall be completed by mechanical operators with the assistance of maintenance personnel.

3. Three-level maintenance:

The key point is to detect, adjust, eliminate hidden dangers and balance the wear degree of each component. It is necessary to carry out diagnostic inspection and condition detection on the components that affect performance and those with fault symptoms, and then complete the necessary replacement, adjustment and troubleshooting. Three-level maintenance requirements are completed by comprehensive technical maintenance personnel with the help of advanced testing instruments and tools.

In short, in order to ensure the safety and performance stability of mechanical products, Hook Machine Mall reminds everyone to carry out regular maintenance of construction machinery.
