What are the classifications of rollers?

It is undeniable that rollers play an effective role in leveling the surface during construction. In order to be suitable for many different purposes, people classify rollers based on their characteristics. For details, let’s learn about the classifications of rollers below with Comacpro.

Vibratory roller

Vibrating rollers are the most popular type of roller today with the outstanding feature of using dynamic force to compact. The normal load of a vibratory roller is usually around 12-16 tons. However, it can reach 25-30 tons when the vehicle is operating.

In terms of structure, vibratory rollers consist of 2 tires and 1 iron wheel and are mainly used for the construction of large traffic roads.

Static roller

Unlike vibratory rollers, static rollers are classified mainly using their own weight throughout the working process. Types of static rollers include:

Steel-wheel roller

This is a type of roller suitable for surfaces mixed with rocks such as asphalt or large car roads. Steel-wheel rollers are made from a roller made of extremely hard steel.

In which, the steel wheel part is where the gravity is concentrated so that when operating, the steel wheel will contact the road surface and help the surface to be smooth and smooth. Before and during operation, the impact force of the roller is constant.

Advantages:

• Ability to compact smooth ground surfaces
• Ability to compact gravel roads, asphalt roads
• Simple structure, low cost

Tire roller

The distinguishing feature of a tire roller is the design of a row of tires arranged horizontally in the front or both the front and rear of the vehicle. Accordingly, the tire part is the position that directly impacts the surface, suitable for all types of soil, including asphalt concrete.

Tire rollers operate through the process of moving the wheel in contact with the road surface and transmitting the load to the ground. During this process, the compaction force is constant.

Advantages:

• The machine has a high working speed
• Adapts to all types of soil, including asphalt concrete roads
• The ability to increase or decrease the load applied to the ground by increasing or decreasing the mass of the machine and the pressure in the tire.

Sheep’s foot roller

The sheep’s foot roller line has a special design with additional lugs that help the machine move forward and not backward like other roller lines. This is also the reason why people call this vehicle a sheep’s foot roller because they look like sheep’s feet.

Lugs come in many different shapes, but the most common are still conical and truncated pyramids.

However, because of this design, sheep’s foot rollers are difficult to move on surfaces that are not too smooth and flat. Normally, this type of vehicle is most suitable for rolling in places with sticky soil and high humidity.

Advantages:

• High compaction quality
• Height has a big impact compared to steel wheel rollers and tire rollers

Hopefully the content of the article classifying rollers has helped readers have more useful information in choosing the right roller.
