Today, let everyone know that when you usually use aerial work platforms, you should check, maintain and maintain them frequently. This will not only extend the service life of aerial work platforms, but also make them more efficient when they work. What are the main points of maintenance for aerial work platforms? For example, the transmission part should have enough lubricating oil, and the vulnerable parts must be frequently checked, repaired or replaced. The mechanical bolts, especially the parts that frequently vibrate, such as the slewing ring and the connecting bolts of the lifting arm, should be checked for looseness, such as If there is any looseness, it must be tightened or replaced. Next, let’s take a look at the regulations on the maintenance time of aerial work platforms:
1. Daily maintenance (per shift).
2. After working for 1500 hours on the aerial work platform, make minor repairs to the mechanical and electrical systems.
3. After 5000 hours of work on the aerial work platform, the mechanical and electrical system shall be repaired.
4. After working for 10,000 hours on the aerial work platform, overhaul the mechanical and electrical systems.
Secondly, let's talk about the maintenance and maintenance of the mechanical equipment of the aerial work platform:
1. The brakes of each mechanism should be checked frequently and the gap between the brake shoe and the brake wheel should be adjusted to ensure flexibility and reliability. There should be no dirt on the friction surface. When there is dirt, it must be washed off with gasoline or thinner.
2. The lubrication of the gearbox, gearbox, external gear and other parts and hydraulic oil are carried out according to the requirements in the lubrication table.
3. Pay attention to check whether there are broken wires and loose strands in the wire ropes. If it exceeds the relevant regulations, it must be replaced immediately. The maintenance of the steel wire rope should strictly follow the regulations of GB5144-85.
4. Check the connection of each part frequently, and tighten it if there is any looseness. The body connecting bolts should be checked for tightness when the body is under pressure (the method of rotating the arm can be used to create the compressed state), all connecting shafts must have cotter pins, and they need to be fully opened.
5. Frequently check whether each mechanism is operating normally and whether there is noise. If any malfunction is found, it must be eliminated in time.
6. When installing, disassembling and adjusting the slewing mechanism, pay attention to ensure that the center line of the slewing mechanism reducer is parallel to the center line of the gear, and the meshing surface is not less than 70%, and the meshing gap should be suitable.
7. Always check all wires and cables for damage. Bandage and replace the damaged part in time.
8. When the motor is overheated, stop in time, and continue to run after troubleshooting. The motor bearing should be lubricated well.
9. The contact surface of each part of the brush should be kept clean, and the pressure of the brush should be adjusted so that the contact area is not less than 50%.
10. All control boxes and distribution boxes should be kept clean frequently, and dust on electrical equipment should be cleaned up in time.
11. The contact opening and closing of the travel switch of each safety device must be reliable, and the contact crater should be polished in time.
