China Mountain Raise Road Roller for Sale
12ton China Mountain Raise Road Roller for Sale
MOUNTAIN RAISE MACHINERY road roller, also known as soil compactor, is a kind of road repairing equipment. Road rollers belong to the category of road equipment in construction machinery. They are widely used in filling compaction operations of high-grade highways, railways, airport runways, dams, stadiums and other large-scale engineering projects. They can compact sandy, semi-cohesive and cohesive soils, Subgrade stabilized soil and asphalt concrete pavement layer. The roller is suitable for various compaction operations by the gravity of the machine itself, so that the compacted layer is permanently deformed and compacted. Road rollers are divided into two types: steel wheel type and tire type.
MOUNTAIN RAISE MACHINERY, as a professional manufacturer of construction machinery, road roller is one of our main products, here to share with you how to use the road roller :
1. During operation, the roller should start before it starts to shake, and the internal combustion engine should be set to medium speed first, and then adjusted to high speed.
2. The engine should be stopped first when shifting and changing directions, and the engine speed should be reduced when shifting.
3. It is strictly forbidden for the roller to vibrate on a solid ground.
4. When rolling a soft roadbed, first roll it 1 to 2 times without vibration, and then vibrate it.
5. When rolling, the vibration frequency should be consistent. For the vibratory roller that can adjust your vibration frequency, you should adjust the vibration frequency before working. Do not adjust the vibration frequency without starting vibration.
6. The adjustment of the reversing clutch, shock clutch and brake should be carried out after the main clutch is disengaged.
7. Fast gear cannot be used when going up or downhill. In sharp turns, including articulated vibratory rollers when rolling in small turns, it is strictly forbidden to use fast gears.
8. The roller must not engage with vibration when it is running at high speed.
9. When stopping, stop the vibration first, then put the reversing mechanism in the middle position, put the transmission in neutral, and finally pull up the hand brake lever, and the internal combustion engine will turn off after idling for a few minutes.
10. Other operating requirements should meet the requirements of static pressure rollers.
① Regardless of whether it is uphill or downhill, the bottom layer of the asphalt mixture must be clean and dry, and the asphalt bonding layer must be sprayed to avoid slippage of the mixture during rolling.
②Whether it is rolling uphill or rolling downhill, the driving wheel of the roller should be behind. This has the following advantages: When going uphill, the rear driving wheel can withstand the driving force provided by the ramp and the machine itself, while the front wheel performs preliminary compaction on the road surface to withstand the greater shearing force generated by the driving wheel ; When going downhill, the impact force generated by the weight of the roller is offset by the braking of the driving wheel, and only the mixture after being rolled by the front wheel can support the rear driving wheel to generate shearing force.
③When rolling uphill, the roller should start, stop and accelerate smoothly to avoid excessively high or low speed.
④Before uphill rolling, the mixture should be cooled to the specified lower limit temperature, and then statically pre-compressed. When the temperature of the mixture drops to the lower limit (120°C), vibration compaction is used.
⑤Sudden speed change and braking should be avoided when rolling downhill.
⑥When rolling downhill under very steep slopes, a light roller should be used for pre-compaction first, and then a heavy roller or vibratory roller should be used for compaction.
