In the process of building and repair of roads, an important role is played by the seal of the base material, which depends on time and further service in this direction. This is done using special equipment called a skating rink. This is a heavy machine that their weight presses all layers of asphalt or other material (it may be sand, gravel, asphalt, and the like. D.). Let's see what kinds of rollers are, and what types they are divided by the method of sealing.
Classification by displacement type
Divide them into three types, they are:
- trailers;
- semi-trailers;
- Self-propelled machines.
Trailer traffic are unable to unauthorized movement. Basically, this is done by a tractor, or other high power machine, as to pull such weight can not each.
Semi consist of:
- Uniaxial tractor;
- Ballast weight;
- frames;
- Of the "wheels".
This variant is not common, because the large size is not always possible to bring it to the streets. Basically, it's construction machinery or extra-urban.
Propelled have the ability to move independently, though not at a high speed. Self-propelled mechanism is applied only during the work, transportation to the space you need, basically, is done by trucks with a special platform.
Classification by type of working body
Rollers road roller ensure maximum pressure on the separate road segment. Smooth roller is the most widely used, as is used for placing public roads. Cam roller effective in compacting loose rocks. Lattice need for heterogeneous soil compaction. Large items are crushed grille that increases the overall density. Pneumatic compactors are those in which serve as roller wheel, combined in a row. In any case, there is a gap, which is also in need of solid masonry. For this, the rear wheels are staggered to the front, allowing you to capture the entire walkable area. Segment rollers have a common roller. Each individual piece has its pressure, they also arranged in a checkerboard pattern. All these types are kompaktornymi.
Special different functions, for which there are other representatives. An example would be ice rinks, which are used to smooth the surface during a hockey match.
There are three types, if we talk about the amount of pressure surfaces, namely:
- Odnovaltsevye;
- Dvuhvaltsevye;
- Trehvaltsevye.
Classification method seal
Modern rollers have some kind of pressure techniques. By types of seals are divided into:
- statistics;
- Vibration.
The first work by its own weight, the latter using an impulsive move. This is the main difference related to possible variations works. Buy a used / have a skating rink on site https://dst-m.ru/katalog/katki/.
