According to the wheel structure, the roller can be divided in to smooth wheel roller, sheep-foot roller and so on. Smooth roller is more widely used in the compacting of road paving. Steel drum rollers adopt the mechanical and hydraulic drive to make the force concentrate on compacting the protuberant. In such way, the compacting effect is pretty good, which is suitable for the compaction of the asphalt pavement.
As per the axle, it can be divided in to single axle with single wheel, double axles with double wheels, double axles with three wheels, and three axles with three wheels etc. Road rollers worked by Internal Combustion Engines adopt the mechanical or hydraulic drive. Usually the front wheel steers with strong maneuverability, and rear wheel drives. To improve the maneuverability and the rolling performance, it is suitable to use the articulated steering rollers and all wheel drive rollers. The structure of the front wheel articulated with the machine frame to decrease the body waving on the rough road. The connection between the rear wheel and the machine frame is rigid links. It adopts the hydraulic control and the hydraulic cylinder steering control. Both the front wheel and the rear wheel are equipped with the scraper to clean the dust. It also equipped with spray system, when compacting the asphalt, the sprinkler can sprinkle to the wheel and prevent the asphalt mixture adhere on the wheels. To increase the acting force, you may add iron, gravel and water in the wheel and increase the operating mass.
The main parameter of the steel drum roller is the machine weight and the linear pressure. In 1980s, the operating mass of the steel drum rollers scope is: double steel drum roller, 2-13tons; 3 drums rollers, 1-15tons. As required, roller weight can add 1-3 tons’. Three axles with three wheels are from 13-14tons, and after adding the weight it weighs 18-19tons.
