How to judge whether the Road Roller needs major maintenance?

1. Running time and mileage
1. Time judgment: Generally speaking, a Road Roller needs to be considered for major maintenance after running continuously for about 2,000 hours. Road Rollers of different models and usage environments may vary, but this is a more common reference time.
2. Mileage judgment: If mileage is used as a reference, major maintenance can be considered for about every 100,000-150,000 kilometers of compaction. Similarly, the actual situation may vary depending on the type of Road Roller, working intensity and working environment.
2. Changes in working performance
1. Decreased compaction effect: If it is found that the compaction density of the compacted road surface is significantly reduced or uneven compaction occurs when the Road Roller is in normal working condition, it may be that some parts of the Road Roller are worn or faulty, and major maintenance is required to check and repair related problems.
2. Insufficient power: When the Road Roller has reduced engine power, slow acceleration, difficulty climbing, etc. during work, it may be that the engine system or transmission system needs major maintenance. For example, the engine may need to check the wear of pistons, piston rings, valves and other components, and the transmission system may need to check the working conditions of clutches, transmissions, drive shafts and other components.
3. Abnormal vibration: If the vibration system of the Road Roller is abnormal, such as unstable vibration frequency, reduced amplitude, increased vibration noise, etc., it may be that there are problems with the vibration motor, vibration pump, vibration bearing and other components, and major maintenance is required to check and replace related components.
4. Unstable walking: If the Road Roller deviates, shakes, bumps and other conditions during walking, it may be that the tires, tracks, travel motors, reducers and other components of the walking system have failed, and major maintenance is required to check and repair related problems.
III. Appearance inspection
1. Oil leakage: If oil leakage is found in the engine, hydraulic system, transmission system and other parts of the Road Roller, it means that the seals may have aged or been damaged, and major maintenance is required to replace the seals and check the wear of related components.
2. Wear of parts: Check the rollers, chains, tracks, brake pads and other easily worn parts of the Road Roller. If serious wear is found, major maintenance should be carried out in time to replace these parts to ensure the normal operation of the Road Roller.
3. Paint peeling and rust: If the appearance of the Road Roller shows paint peeling, rust, etc., it means that the surface protection of the Road Roller has been damaged, which may cause further corrosion of the parts. At this time, you can consider major maintenance, and carry out comprehensive rust removal and painting of the Road Roller to extend its service life.
IV. Equipment use environment
1. Harsh working environment: If the Road Roller is often used in harsh working environments, such as high temperature, high humidity, dusty, corrosive environment, etc., the wear and aging of the equipment will accelerate. In this case, more frequent major maintenance may be required to ensure the performance and reliability of the equipment.
2. Heavy-load work: If the Road Roller often performs heavy-load compaction operations, the various parts of the equipment are under great pressure and are prone to fatigue and damage. For Road Rollers working under heavy load, pay close attention to their working performance and component wear, and carry out major maintenance in a timely manner.
