Maintenance skills
1. Daily maintenance, cleaning and maintenance: The crane should be cleaned in time after use, and external parts and electrical components should be cleaned to prevent dirt from adhering.
2. Refueling and maintenance: The oil in the crane should be replaced regularly. For example, the hydraulic oil should be cleaned of moisture and impurities from the bottom drain port every half month, and all hydraulic oil should be replaced every one year (or after 2000 hours of operation). If the oil does not deteriorate, the oil change interval can be extended appropriately.
3. Electrical appliance maintenance: Cleaning of the electrical system is very important. Electrical connectors should be checked frequently to prevent corrosion and do not scratch the electrical connectors.
4. Tire maintenance: When the crane tires are no longer in use, they should be replaced in time. At the same time, please pay attention to the tire pressure standards and whether there are cuts, aging, etc.
5. Regularly check the lubrication system: Regularly check the lubricating oil usage of the crane, including the addition of lubricating oil, the use cycle and the type of lubricating oil.
6. Electrical components: Check whether the connections of electrical components are tight and whether the wires are worn or broken.
7. Wire rope: Check the wire rope for wear, distortion, spots, etc.
8. Maintenance of mechanical parts: Check the brakes, operation status of each mechanism, tightening of connecting bolts, wire ropes, etc. If any fault occurs, it should be eliminated in time.
9. Hydraulic system: Add or replace hydraulic oil on time, and check oil pipes and their joints, safety valves, hydraulic pumps and hydraulic cylinders, etc.
10. Waterproofing: When the weather is excessively dry or humid, the crane needs to be waterproofed to ensure the safety of electrical components.
Precautions
1. Safe use: During the unloading process, special attention needs to be paid to the function of the lowering brake to ensure the safety performance of the crane.
2. When installing the crane, make sure the base is stable and prevent the bottom from loosening to avoid accidents during work.
3. Fire safety: The sun is strong in summer, so you should avoid parking the car for a long time under the sun to avoid spontaneous combustion.
4. Cranes and other equipment should be equipped with fire extinguishers for use in emergencies.
5. Avoid long-term overload operations. Under high temperatures in summer, the wear and aging of various parts of the crane will accelerate. Long-term overload operations should be avoided as much as possible.
Following the above maintenance tips and precautions can ensure that the crane remains in good condition during operation and improves the service life and safety of the equipment.
