In the field of engineering construction, rollers are vital equipment, and their good condition has a significant impact on the quality and progress of the project. Proper maintenance of rollers is the key to ensuring their efficient operation and extending their service life.
After operation, the roller should be thoroughly cleaned. Clean the dust, dirt and debris on the surface of the equipment to maintain a neat appearance. Clean the cab glass and dashboard to provide the driver with a good view and a comfortable operating environment. For vibrating wheels and tires (if it is a tire roller), clean up the attachments in time to prevent affecting the compaction effect and damaging the parts. It is essential to check the oil every day. Check the engine oil level to ensure that it is within the normal range. If the level is too low, add oil that meets the specifications in time. Pay attention to the hydraulic oil level and cleanliness. If the color becomes darker or there are impurities, it should be replaced immediately. Also check the coolant level to ensure that the engine cooling system is working properly. For tire rollers, check whether the tire pressure is normal and whether there is any damage or excessive wear. Inflate in time if the air pressure is insufficient, and repair or replace if there is any damage. For crawler rollers, check whether the track tension is appropriate and whether there are broken or severely worn links. If it is too loose or too tight, adjust it in time, and replace it in time if it is damaged.
The electrical system inspection should not be ignored. Ensure that the dashboard indicators and instruments are working properly, and eliminate faults in time. Check whether the wires and plugs are loose or damaged to prevent electrical failures. Change the engine oil and filter regularly according to the equipment manual. Generally, the engine oil and filter are replaced every 500 hours of work. The hydraulic oil and filter also need to be replaced regularly, usually once every 1000 hours of work to ensure the normal operation of the hydraulic system. The performance inspection and adjustment of the brake system cannot be ignored. Regularly check the wear of the brake pads, the brake fluid level and cleanliness. Replace it in time if it is excessively worn, and add or replace it in time if the brake fluid is insufficient or deteriorated. Adjust the brake system clearance to ensure sensitive and reliable braking.
The vibration system needs to be checked and adjusted regularly. Check the wear of bearings, eccentric blocks and other components, and replace them in time if they are worn. Adjust the vibration frequency and amplitude to ensure that the compaction effect meets the requirements. Engine maintenance is important. Check the intake system, fuel system and exhaust system regularly, and clean the carbon deposits and debris in the air filter, fuel filter and exhaust pipe. Check the ignition system and cooling system to ensure that the engine is working properly. Lubricate each lubrication point regularly, including the drive shaft, steering mechanism, vibration wheel bearing, etc. Use lubricating oil that meets the specifications to ensure good lubrication.
If the roller needs to be stored for a long time, special maintenance should be done. After cleaning, apply anti-rust oil and store it in a dry and ventilated place. Remove the battery and store it in a dry and safe place and charge it regularly. Loosen the track or tire pressure to prevent deformation during long-term storage. In winter maintenance, use engine oil, hydraulic oil and coolant suitable for low-temperature environments to prevent equipment from starting difficulties or damage at low temperatures. Take anti-cold measures when storing outdoors, such as covering with insulation materials. In summer maintenance, pay attention to prevent equipment from overheating. Increase the number of radiator cleanings to ensure good heat dissipation. Avoid long-term operation during high temperature periods to prevent equipment from overheating and damage.
For second-hand dealers, the maintenance status of the roller directly affects the value of the equipment and sales prospects. When purchasing a used roller, you should carefully check the maintenance records and actual condition. If the maintenance is not done properly, consider adjusting the sales price or performing maintenance and repairs to improve the performance and value of the equipment. Second-hand dealers can provide professional advice and guidance to customers. During the sales process, detailed maintenance points and methods are introduced to let customers know how to properly maintain the roller and extend its service life. At the same time, after-sales service for a certain period of time, including maintenance and repairs, is provided so that customers have no worries.
In short, proper maintenance of the roller can keep it in good condition and provide strong support for engineering construction. Second-hand dealers play an important role in this, providing high-quality second-hand rollers through professional services and guidance to promote the development of the engineering construction industry.
