Rollers are widely used in road construction, soil compaction and other engineering projects. However, some common faults may occur in second-hand rollers during use. Understanding these faults and their repair methods is essential to improve the efficiency of equipment use and extend its service life. The following are some common faults of second-hand rollers and their repair methods.
Fault manifestation: When the roller is started, the engine cannot run normally, or it takes several attempts to start.
Fuel system problems: insufficient fuel, fuel pump failure or filter blockage.
Battery problems: insufficient power or loose cable connection.
Engine failure: ignition system failure or insufficient compression.
Check the fuel reserve to ensure sufficient fuel, and check the fuel pump and filter.
Measure the battery voltage, charge or replace the battery if necessary, and check whether the cable connection is firm.
Check the ignition system to ensure normal ignition, replace the spark plug or repair the engine if necessary.
Fault manifestation: The roller shakes, vibrates or is unstable during driving.
Uneven wear of tires or rollers.
Failure of the hydraulic system, resulting in insufficient or leaking hydraulic oil.
Suspension system failure.
Check the wear of tires and rollers, and replace or trim if necessary.
Check the hydraulic oil level, add or replace hydraulic oil, and repair possible leaks.
Check the components of the suspension system to ensure that all connections are secure and not damaged.
Failure manifestation: When the roller is in operation, the hydraulic system cannot work properly, causing slow movement or failure.
Insufficient or deteriorated hydraulic oil.
Failure of the hydraulic pump.
Leakage of hydraulic pipeline.
Check the hydraulic oil level, add new oil if necessary, and replace the hydraulic oil regularly.
Check the hydraulic pump to ensure that it is working properly, and repair or replace it if necessary.
Check the hydraulic pipeline, find the leak and repair it.
Failure manifestation: The operating lever or button cannot control the movement of the roller properly.
The control cable is worn or broken.
Electrical system failure.
Faulty operating control valve.
Check the control cable and replace if necessary.
Check the electrical system to ensure that the circuit is normal and repair the circuit if necessary.
Check the operating control valve to ensure that it is working properly and repair or replace it if necessary.
Fault manifestation: During the operation of the roller, the engine temperature is too high, which may cause flameout or damage.
Cooling system failure, insufficient coolant or pump failure.
Carbon deposits or dirt inside the engine.
Excessive workload.
Check the coolant level, add coolant if necessary, and check the cooling pump and radiator.
Clean the inside of the engine and change the oil and filter regularly.
Ensure the workload is appropriate and avoid overload operation.
Understanding the common faults of second-hand rollers and their repair methods can help operators detect problems early, reduce downtime and improve work efficiency. Regular equipment maintenance and timely handling of faults will help extend the service life of the roller and ensure the smooth progress of the project.
