Road roller, also known as soil compactor, is a kind of equipment for road repair . 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.

There are mainly the following types of engines for road rollersBFM2012 BFM1013 TCD2012 TCD2013Today we will introduce the most commonly used road roller engine BF4M2012

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 reversing, and the speed of the internal combustion engine 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.
