Common Problems To Pay Attention To When Buying a Second-Hand Roller

When purchasing a used roller on a second-hand construction equipment wholesale website, you need to carefully consider the following aspects to ensure that you buy equipment that is cost-effective and can be used normally.

1. Equipment appearance inspection

Overall condition: Observe the overall appearance of the roller to see if there are obvious collision marks, cracks or deformations. If there is severe damage to the appearance, it may mean that the equipment has suffered a major accident and the internal structure may also be affected.

Paint condition: Pay attention to the degree of wear of the paint and whether there are signs of repainting. If the paint in some areas is severely peeling, it may be due to rust caused by long-term use or environmental erosion; and repainting may be to cover up certain defects.

Tire or track condition: For tire rollers, check the wear of the tires, including tread depth, whether there are bulges or damage. For crawler rollers, check the tightness of the tracks, the wear of the chain links, and whether there are any breaks, which will affect the driving stability and work efficiency of the roller.

2. Engine inspection

Starting performance: Start the roller and pay attention to whether the start is smooth and quick. If it is difficult to start, there may be an engine fault, such as a dead battery, a faulty starter motor, or a fuel system problem.

Running sound: Listen carefully to the sound of the engine while it is running. The normal engine sound should be smooth, continuous, and without abnormal knocking, friction, or whistling. Abnormal sounds may indicate wear or damage to the internal parts of the engine.

Exhaust color: Observe the color of the exhaust, which should be colorless or light gray under normal circumstances. If the exhaust is black, blue, or white and thick, it may indicate that the engine has problems such as incomplete combustion, burning oil, or coolant leakage.

3. Working device inspection

Vibration system: For rollers with vibration function, check whether the vibration system is working properly. After starting the vibration function, feel the intensity and stability of the vibration, and whether there is abnormal vibration or lack of vibration, which may be related to components such as vibration motors and vibration bearings.

Roller roller: Check the surface wear of the roller for uneven wear or damage. The wear of the roller will affect the flatness and effect of the roller. At the same time, check whether the roller rotates smoothly and whether there is any jamming.

4. Equipment history and documents

Maintenance records: Try to obtain the maintenance records of the roller to understand the equipment's past failures and maintenance content, which will help evaluate the equipment's potential problems and remaining service life.

Service life and working hours: Clarify the roller's service life and working hours, which is an important basis for judging the degree of equipment wear. Generally speaking, equipment with a long service life and a large number of working hours is more likely to have aging and wear of parts.

5. Price and after-sales

Price rationality: By comparing with the prices of second-hand rollers of the same type and condition on the market, judge whether the current equipment price is reasonable to avoid buying at a high price.

After-sales guarantee: Ask the seller whether it provides after-sales guarantee, such as a certain period of quality assurance or maintenance support, which can reduce losses when problems arise after purchase.
