Road roller manufacturer shows you the difference between types of road roller

A road roller, also known as a compactor, is common construction machinery. Using its own mechanical gravity, the rolled layer can be deformed and compacted. It is widely used in the filling and compaction of large-scale projects such as mines, highways, railways, airport runways, dams, and stadiums. Road rollers are divided into steel wheel types and tire types. Today, Luoyang Road Roller will show you the difference between a tire roller and a drum roller.

FYEBOON road roller tells you that the positioning is different.

1. Tire rollers

A tire roller is a machine that compacts the road surface with multiple pneumatic tires. The grinding wheel adopts pneumatic tires, generally 3 to 5 front wheels, and 4 to 6 rear wheels. If you change the inflation pressure, you can change the ground pressure, and the pressure adjustment range is 0.11 ~ 1.05 MPa.

2. Drum roller

The roll structure of the steel roll includes a smooth roll, a grooved roll, and a sheep’s foot roll. Smooth grinding is widely used, mainly for road compaction. According to the axles, there are single-axle single-wheel, double-axle double-wheel, double-axle three-wheel, and three-axle three-wheel. Mechanical equipment that uses its own gravity and vibration to compact various building and road construction materials. In highway construction, compactors are suitable for compacting various non-cohesive soils, crushed stones, crushed stone mixtures, and various asphalt concrete materials, so they are widely used.

FYEBOON road roller tells you the difference in characteristics

1. Tire rollers

The specific ground pressure can be adjusted by increasing or decreasing the weight and tire pressure to suit the compaction of different materials. The third forward gear and the second reverse gear can be changed from 5.33 km/h to 22.05 km/h, which is convenient for construction and transition. The front-wheel adopts a mechanical swing suspension device. It has service brakes, parking brakes, and reliable braking performance. The panoramic cab with a wide field of view has good sound insulation and vibration reduction effect.

2. Drum roller

Adopt articulated frame, hydraulic walking, hydraulic vibration, and a fully hydraulic steering system. It has two vibration frequencies and two levels of amplitude, which can be applied to the compaction of different thickness pavements and various materials. Imported hydraulic pump, hydraulic motor, and vibration bearing ensure the reliability of the whole machine. The frame cover has an optimized design for easy maintenance and repair. Three-stage vibration reduction, the cab is sealed and soundproof, and the driving is more comfortable.

In addition, in addition to the vertical compressive strength, the tire roller also has lateral compressive strength, which not only acts in the driving direction but also acts in the lateral direction of the machine. The densification is obtained because the pressure can move the material particles in all directions. These forces, combined with a “kneading action” created by the rubber tires, produce good compaction. If the asphalt mixture is compacted with a drum roller, the contact of the drum will form a “bridge” phenomenon between the large particles of the asphalt mixture, and the gaps left by this “bridge” will cause uneven compaction.
