Small road rollers are also called walking rollers. At present, the domestic production of small road rollers is divided into walking single-wheel road rollers. Handheld two-wheeled road rollers; there are three types of road rollers. The engine is divided into diesel engine and gasoline engine. Selection of small roller: viscous materials should be selected with static roller; for static roller, if the roadbed is pressed, three-wheel roller is used, if the road surface is pressed, two-wheel roller is used.

Crash roller is suitable for crushing cohesive soil, crushing dam sealing layer is good equipment, but not suitable for crushing surface layer. Non-cohesive materials Luoyang Agricultural Machinery suggests using vibratory rollers. When the water content of the crushed material is low and it is difficult to wet with water, heavy roller should be selected. When the water content of the crushed material is large and the dry weight is low, a light roller should be selected.

Tire rollers can be applied to various types of crushed materials and compact asphalt pavement with good effect. Small rollers are suitable for small projects, narrow places (municipal road repair, rural road reconstruction, garden bridges, residential roads, etc.), trench filling projects or large rollers to supplement the grinding and maintenance works. In practice, a single type of roller is often difficult to complete the whole project compaction process, usually need to use large, medium and small size with each other or a variety of combinations. Therefore, the choice of roller and equipment to consider the type of project, construction scale and compaction operation of the allowable time and other factors. In short, it is necessary to make an economic and reasonable choice on the basis of comprehensive analysis and comparison of all aspects.

The basic configuration of small road roller is mainly composed of engine, hydraulic system, steel ring, shaker and operating handle. The engine has diesel engine and gasoline engine. At present, China's small road rollers can be divided into three types: walking single-wheel rollers, walking double-wheel rollers and vehicle-mounted rollers.

What are the characteristics of Luoyang road roller

Luoyang roller manufacturers believe that impact rollers are a new type of roller after smooth rollers and vibratory rollers. With its huge impact energy and high driving speed, it can achieve deeper compaction effect and higher compaction efficiency, and has been widely used in highway, railway subgrade and airport treatment.

Some knowledge points of Luoyang road roller

Luoyang road roller manufacturers believe that road rollers have wider requirements for filler moisture content, which can be reduced by 3%-5% in the up and down direction. Basically, after filling and leveling the soil, the advantages are more obvious, especially in arid or semi-arid areas. The moisture content in these areas is very low, some approaching 0%-1%. The impact roller only needs to spray a small amount of water on the surface to be rolled, which greatly reduces the compressed water and reduces the construction cost.

The characteristics of the road roller, Luoyang road roller manufacturers for you to explain

Luoyang roller manufacturers believe that in highways, railways, airports, water conservancy projects and construction projects, rollers are mainly used to compact roadbeds, pavements, dams, cofferdams, building foundations, etc. Small rollers are suitable for compacting narrow spaces. The so-called compaction means that through rolling and impact, external forces overcome the friction and cohesion between soil, sand, gravel, and asphalt mixture particles to rearrange themselves, move closer to each other, squeeze out water and air, and increase the friction between the material particles. and the cohesion becomes greater, the compacted material will be denser.
