China Transport Group is a large-scale modern enterprise and manufacturing enterprise integrating scientific research, design, production, processing, sales, logistics and transportation. The China Transport Group is mainly engaged in large-scale construction machinery and equipment, railway equipment, engineering machinery, road transportation equipment, marine equipment, aviation equipment and other products. The road roller is one of the main business products of China Transport Group.The road roller belongs to the category of road equipment in construction machinery.Road roller is widely used in the filling and compacting of large-scale projects such as high-grade roads, railways, airport runways, dams and stadiums. Road roller can crush sand, semi-stick and sticky soil. Subgrade stabilized soil and asphalt concrete pavement layer.
Many customers' perceptions of road rollers only stay on the above basic uses. Most of them don't know how to operate the roller correctly, and they do not know what details should be paid attention to during use. In response to these questions about the road roller, we have compiled the following rules for users reference:

1. When working, the road roller should start before it starts to vibrate. The internal combustion engine should first reach the medium speed and then modulate the high speed.

2. When shifting and reversing, stop first, and reduce the engine speed when shifting.

3. It is forbidden to vibrate the road roller on a solid ground.

4. When crushing the soft roadbed, it should be crushed 1~2 times without vibration, and then vibrated and crushed.

5. When rolling, the vibration frequency should be consistent. For the vibratory roller that can adjust your vibration, you should adjust the vibration frequency before working. Do not adjust the vibration frequency without shaking.

6. Adjustment of the reverse clutch, the starting clutch and the brake should be performed after the main clutch is disengaged.

7. When using up and downhill, you cannot use the fast file. In the case of sharp turns, it is strictly forbidden to use the quick gear when the articulated vibratory roller is rolled in a small turning circle.

8. The road roller must not engage the vibration when driving at high speed.

9. Stop the vibration first, then put the reversing mechanism in the middle position, the transmission is placed in the neutral position, and finally the hand brake lever is pulled up. The internal combustion engine is turned off after several minutes of idling.

10. Other operation requirements shall comply with the regulations of the static pressure road  roller.

1 Whether it is uphill or downhill, the bottom layer of the asphalt mixture must be clean and dry, and the asphalt binder layer must be sprayed to avoid slipping of the mixture during rolling.

2 Whether it is uphill crushing or downhill rolling, the drive wheel of the road roller should be behind. This has the following advantages: when going uphill, the rear drive wheel can withstand the driving force provided by the ramp and the machine itself, while the front wheel preliminarily compacts the road surface to withstand the large shear force generated by the drive wheel. When going downhill, the impact force generated by the self-weight of the road roller is offset by the braking of the driving wheel. Only the mixture after rolling by the front wheel has the ability to support the driving wheel to generate shearing force.

3 When rolling uphill, the road roller should start, stop and accelerate smoothly, avoiding the speed being too high or too low.

4 Before rolling uphill, the mixture should be cooled to the specified low temperature, and then static preloading. When the temperature of the mixture drops to the lower limit (120 °C), the vibration compaction is adopted.

5 Downhill rolling should avoid sudden shifting and braking.

6 When carrying out downhill crushing under steep slope conditions, the light road  roller should be used for pre-pressing, and then compacted by heavy-duty road roller or vibratory roller.

Through the above introduction, have you already understood how to operate the road roller correctly? For other questions about the road roller, please feel free to call us, we will be happy to help you!!!
