The damage of road rollers during operation is often related to improper operation and maintenance. Here are the common causes of damage and protection points for the equipment:

I. Malfunctions Caused by Lack of Operational Standards

Most early-stage damages of road rollers stem from operational errors. Starting, debugging, or shutting down the equipment without following the manual procedures can easily cause component overload. For example, high-load operation without preheating will aggravate engine wear. It is essential to study the equipment manual carefully before operation and strictly follow the standard procedures, which can significantly reduce the risk of human-induced failures.

II. Inadequate Periodic Maintenance

Road rollers usually work in harsh environments, and long-term rolling operations will accumulate vibration stress and mechanical wear. If filters, engine oil, or fasteners are not replaced or inspected as per the specified cycle, minor hidden dangers may evolve into structural damages. Regular maintenance can timely detect issues like loose bolts or aging seals, preventing failures from expanding.

III. Insufficient Lubrication System Maintenance

Poor lubrication is one of the main causes of component damage in road rollers. If transmission components such as gearboxes and bearings lack oil, high temperature generated by increased friction may lead to metal surface wear or sintering. It is necessary to add suitable grease according to the lubrication points and cycles marked on the equipment to ensure the effective operation of the lubrication system and reduce mechanical wear.

IV.  Losses Caused by Improper Temperature Control

1. Overload Operation at Low Temperatures: In low-temperature environments, the viscosity of the engine oil in road rollers increases, and the resistance of components operation rises. If the equipment is operated at high speed without sufficient preheating, the engine piston rings and cylinder walls are prone to scoring due to insufficient lubrication. After starting, it should idle until the water temperature reaches the standard before loading.

2. High-temperature Heat Dissipation Failure: During long-term high-intensity operation, if the cooling system is blocked by dust (air-cooled type) or the coolant is insufficient (water-cooled type), the engine may overheat, causing cylinder gasket damage or circuit aging. Regularly clean the cooling passages and check the coolant level to avoid equipment operation under overheating conditions.

V.  Neglect of Cooling System Maintenance

Water-cooled road rollers need to check the coolant level daily to avoid "dry burning" due to water shortage; air-cooled equipment should periodically clean the dust on the radiator fins to ensure smooth air ducts. Ignoring the maintenance of the cooling system can cause engine overheating and efficiency reduction, or even lead to serious damages such as cylinder deformation.

Conclusion

The durability of road rollers depends on scientific operation and meticulous maintenance. Operators should strengthen awareness of standardization, implement regular maintenance, lubrication management, and temperature monitoring, and timely inspect cooling system hidden dangers to reduce abnormal equipment damage, extend service life, and ensure construction efficiency.
