Maintenance of Mechanical Equipment
1. The brakes of each organization should be regularly checked and adjusted for the clearance between the brake pads and brake wheels to ensure flexibility and reliability. Clearance ensures between 0.5 and 1mm. There should be no dirt on the friction surface, and any dirt must be washed off with gasoline and thinner.
2. The lubrication of various parts such as the gearbox, gearbox, and external meshing gears, as well as the hydraulic oil, are carried out according to the lubrication table requirements.
3. Pay attention to checking each part of the steel wire rope for broken wires and loose strands, and it must be replaced immediately.
Regularly check the connection of each component, and if there is any looseness, it should be pre-tightened. The connecting bolts of the tower body should be inspected when the tower body is under pressure.

4. Check the tightness (the method of rotating the arm frame causes compression), all connecting pin shafts must be equipped with split pins and must be opened.
5. Regularly check whether the operation of each institution is normal and whether there is any noise. If any faults are found, they must be eliminated in a timely manner.
6. When installing, disassembling, and adjusting the rotary mechanism, attention should be paid to ensuring the center of the small gear of the rotary mechanism and the large gear of the rotary support.
The lines are parallel, the meshing surface should not be less than 70%, and the meshing clearance should be appropriate.
