2024-06-29 19:11:03

The maintenance of construction machinery is crucial for extending the service life of equipment, ensuring work efficiency and safety. Proper maintenance can reduce the occurrence of malfunctions, lower repair costs, and maintain the optimal operating condition of equipment. Here are some basic steps and suggestions for maintaining construction machinery:
1. Regular inspection and maintenance:
Check all fasteners for looseness, especially tire nuts, screws, and bolts.
Clean the equipment, remove dust, dirt, and other impurities to prevent them from corroding mechanical components.
Check and replace worn components such as belts, chains, bearings, and seals.
Regularly inspect the electrical system, including batteries, wires, and connectors, to ensure that there is no damage or corrosion.
2. Lubrication:
Lubricate all moving parts, including bearings, joints, gears, and chains, using appropriate lubricants according to the manufacturer's recommendations. Be careful not to apply butter on bolts and nuts, as this will weaken their self-locking performance.
3. Maintenance of hydraulic system:
Regularly check the cleanliness and level of hydraulic oil, and replace filters in a timely manner.
Pay special attention to the sealing of the hydraulic system in winter to prevent leakage.
Use intelligent monitoring devices to assist in checking the health status of hydraulic systems.
4. Engine maintenance:
Regularly replace the engine oil and oil filter element, using original parts or equivalent quality substitutes.
Check the air filter and clean or replace it if necessary.
Ensure that the cooling system is functioning properly, the antifreeze is sufficient and has not expired.
5. Electrical system:
Check and clean the battery terminals to ensure good contact.
Regularly test the functionality of the generator and starter motor.
6. Storage and sealing:
If the equipment is not used for a long time, it should be stored in a dry and sheltered place.
Disconnect the battery and properly seal it.
Place the mechanical fuel control lever in the idle position and all control levers in the neutral position.
7. Seasonal maintenance:
Perform special maintenance during seasonal changes, such as checking the heating system and antifreeze measures before winter arrives.
Pay attention to additional maintenance of the cooling system in high temperature environments.
8. Maintenance under special climatic conditions:
In hot, cold, or high-altitude conditions, take additional preventive measures, such as using oil products suitable for the local climate.
9. Follow the manufacturer's guidelines:
Refer to the user manual and maintenance manual of the device, and follow the manufacturer's recommended maintenance plan and procedures.
10. Professional inspection and maintenance:
Regularly invite professional technicians to conduct comprehensive inspections, identify potential issues, and promptly fix them.
By implementing the above maintenance measures, the reliability and service life of construction machinery can be significantly improved, reducing unexpected downtime and maintenance costs.
