Road Compactor, also known as a compactor, is a road repairing device. The road roller belongs to the category of road equipment in construction machinery. It is widely used in the filling and compacting of large-scale projects such as high-grade roads, railways, airport runways, dams, and stadiums. It can crush sand, semi-stick and sticky soil. Subgrade stabilized soil and asphalt concrete pavement layer. The roller is applied by the gravity of the machine itself and is suitable for various compaction operations so that the pressed layer is permanently deformed and compacted. The roller is divided into two types: steel wheel type and tire type.

Road Compactor

Classified by roller

The structure of the roller is light mill, groove mill, and sheep foot mill. Light roller applications are the most common and are used primarily for the Drum Vibratory Road Roller.

The surface is laminated. It adopts mechanical or hydraulic transmission, which can concentrate the compaction of the protruding part, and has high compactness and flatness, which is suitable for asphalt pavement compaction operation.

Classified by axle

According to the axle, there are single-axis single-wheel, double-shaft two-wheel, two-axis three-wheel and three-axis three-wheel. Powered by internal combustion engines, mechanical transmission or hydraulic transmission. Generally front wheel steering, good maneuverability, rear-wheel drive. To improve steering and rolling performance, an articulated steering structure, and all-wheel drive are preferred. The front-wheel frame and the frame are hinged to reduce the body swing when the road surface is not flat. The rear wheels and the frame are rigidly coupled. Hydraulically operated, hydraulic cylinders are used to control steering. The front and rear drums are equipped with scrapers to remove the bond on the drum. It is also equipped with a water spray system for sprinkling water on the drum to prevent the asphalt mixture from adhering. In order to increase the force, iron, sand, water, etc. may be added to the drum to increase the weight.

History and development

As early as in ancient times, people used the hoofs of the herd to trample the soil, smash and compact to deal with the foundation of the house, compact the dam and the river embankment. Before the mid-19th century, the western road works with gravel. Sub-paving is the main one. The compaction is mainly carried out by the natural rolling of the vehicle. After the invention of the rolling stone machine in 1858, the development of the gravel pavement was promoted, and the compaction work with the horse-drawn roller gradually appeared. This is the earliest The prototype of the roller was introduced. In 1860, a steam roller appeared in France, which further promoted and improved the construction technology and quality of the gravel pavement and accelerated the progress. At the beginning of the 20th century, the world recognized that gravel pavement was the best road at that time and was promoted to the whole world. The concept of compaction was gradually known. The road roller also appeared on various road construction sites. In the mid-19th century, the invention of internal combustion engines has brought tremendous vitality to the development of compaction equipment. The first internal combustion engine-driven roller was born in the early 20th century. Subsequent to the tire roller, the sheep foot roller compactor and the light roller compactor were produced at the same time. The compaction effect of the static roller was studied. It is believed that increasing the weight of the roller can increase the line pressure of the roller and increase the pressure. Real effect. Therefore, for a long period of time, people have been committed to the development of large-tonnage road rollers. The largest tire roller has weighed more than 200 tons. However, during this period, the changes in the road roller mainly reflected the improvement of power and shape. We are Road Compactor Manufacturer, welcome to come to us.
