Various of Road Rollers

Road rollers belong to the category of road equipment in construction machinery and are widely used for compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, stadiums, etc., and can be used for rolling sand, semi-viscous and sticky soils. Subgrade stabilized soil and asphalt concrete pavement.

The static pressure roller uses the gravity of the machine itself and is suitable for all kinds of compaction operations, so that the laminated layer is permanently deformed and compacted. It is divided into two types: steel wheel type and tire type.

Steel wheel roller

Drum construction includes light mill, slot mill and sheep foot mill. Light mills are most commonly used and are mainly used for compaction of pavement surfaces. The use of mechanical or hydraulic transmission, can concentrate the compaction of the protruding part, compaction high flatness, suitable for asphalt pavement compaction operations.

There are single-axis single-wheel, double-axis double-wheel, double-axle three-wheel and three-axle three-wheel and so on. It is powered by an internal combustion engine and uses mechanical transmission or hydraulic transmission. General front-wheel steering, good maneuverability, rear-wheel drive. In order to improve steering and rolling performance, articulated steering structure and all-wheel drive should be adopted. The front wheel frame and the frame are hinged to reduce the body's swing when the road is uneven. The rear wheel and frame are rigidly connected. Hydraulically operated, hydraulic cylinders control steering. The front and rear drums are equipped with a scraper to remove the adhesive on the drum. It is also equipped with a water spray system that is used to compact the asphalt wheel when it is compacted to prevent the asphalt mixture from adhering. In order to increase the force, iron, sand and water can be added to the roller to increase the weight.

The main technical parameters of the drum roller are the machine weight and line pressure. The weight range of various steel roller compactors in the 1980s ranged from 2 to 13 tons of two-wheel rollers, 1 to 15 tons of three-wheel rollers, and 1 to 3 tons of heavy-pressurizers as required, and 13 to 14 tons of three-axle and three-wheel rollers. After the pressurization, it was 18-19 tons.

Tyre type roller

Drums are equipped with pneumatic tires, generally with 3 to 5 front wheels and 4 to 6 rear wheels. If changing the inflation pressure can change the ground pressure, the pressure adjustment range is 0.11 ~ 1.05 MPa. The tire-type roller adopts hydraulic, hydraulic or mechanical transmission system, single-axis or full-shaft drive, wide-base tire articulated frame structure support at three points. The compaction process has a rolling effect, so that the particles of the compacted layer are not broken and embedded, and are even and dense. Good maneuverability, fast speed (up to 25 km/h), used for compaction of roads, airports and other engineering cushions.
