What is the structure of a small road roller?

A road roller, also known as a compactor, is a type of road maintenance equipment. Road rollers belong to the category of road construction equipment in construction machinery. It is used for filling and compaction of high-grade highways, railroads, airport runways, dams, stadiums and other large-scale projects. It can crush sandy, semi-cohesive, cohesive soil, roadbed stabilized soil, asphalt concrete pavement. Due to the gravity of the machinery itself, the road roller makes the compacted layer non-deformed and dense, and is suitable for various compaction operations. Road rollers are divided into steel wheel type and tire type. Then, what is the structure of small road roller?

What is the structure of small roller?

Small drum in the structure is mainly divided into single steel drum and double steel drum; function is mainly divided into semi-hydraulic vibratory roller and fully hydraulic vibratory roller; tonnage mainly includes: 2-2.5 tons, 3-3.5 tons; name is mainly divided into: small single-wheel vibratory roller, small two-wheeled vibratory roller, small hand-held vibratory roller; at present, the domestic small roller is divided into walking single-wheeled roller; hand-held two-wheeled Road rollers and other three kinds of road rollers. The engine is divided into diesel and gasoline engines.

What are the types of small road rollers?

1, table vibration roller

Roller structure includes light roller, groove roller and sheep foot roller. Light grinding is a common application, mainly used for road compaction. Adopting mechanical or hydraulic transmission, it can focus on compaction of the protruding part, with high compaction flatness, and is suitable for asphalt pavement compaction and flattening.

2、Categorized by axle

According to the axle arrangement, there are single-axle single-wheel, double-axle double-wheel, double-axle three-wheel, three-axle three-wheel. It is powered by internal combustion engine and adopts mechanical transmission or hydraulic transmission. It generally has front wheel steering for good maneuverability and rear wheel drive. In order to improve the steering and rolling performance, articulated steering structure and all-wheel drive should be used. The front wheel frame is articulated to the frame to reduce body sway on uneven road surfaces. and the rear wheel frame is rigidly connected. Hydraulic control and hydraulic cylinder control steering are adopted. Front and rear rolls are equipped with scrapers for removing adhesive from the rolls. It is also equipped with a water spraying system for spraying water on the sand wheels while compacting the asphalt pavement to prevent the asphalt mixture from bonding. To increase the force of action, iron, sand and water. can also be installed in the grinding wheel to increase the weight of compaction.

What are the advantages of small road roller?

1, small operating radius, can be constructed in a relatively narrow area, the transition is also relatively free.

2, relatively good performance. Often use 178 engine, strong power, more stable construction.

3, full hydraulic direct drive, equipped with ECO electronic control management system, stepless variable speed, back and forth walking, hydraulic SAAO steering;.

4、One key control electric starter, remote electric starter. Insert the key, gently twist the electric starter, easy and simple operation. Power display light indication;.

5、Front and rear auxiliary wheel support, auxiliary wheel support to enhance the safety factor, boring machine processing quality.
