Manual roller
A hand roller uses pressure and static force to smooth surfaces. To make this type of roller heavier, the inside of the roller tank must be filled with oil or water, the volume of water or oil can be different according to the capacity of the roller. Types of manual rollers based on size: 40 cm 45 kg, 50 cm 55 kg and 60 cm 60 kg. The components of the manual roller are: central lever, two side levers, bearing, roll or roller drum and drum valve for filling water or oil.
Single drama roller
The single drum roller is a type of heavy machinery. The front of this roller has a giant drum while the rear has special tires. These tires are very strong and can prevent the risk of puncture well. These heavy duty tires are needed when you work on rough roads and tracks with these rollers. In the single drum roller, the driver sits in the middle part of the car, which is called the cabin roller. The roller cabin section is located at the top of this car and gives the driver a great view of the surrounding area; Therefore, the driver can easily see the places where he uses the roller. The beating power of single-drum rollers is 2 tons, and they are less powerful than double-drum rollers.
Two drama roller
The main difference between the single drum roller and the double drum roller is that the double drum roller does not have rubber. Whether this car has no tires is good or bad, depends on your job. A double-drum roller can smooth the objects in front and behind the driver at the same time. The working process of this roller is that the drums move the roller while smoothing the surrounding items and paths; For this reason, double-drum rollers never have the tension of single-drum units. You will definitely not use these vehicles for specialized work. But it should be noted that these rollers perform best on flat or gradually graded roads. This type of roller has more force for pounding than single ram rollers, whose force reaches a maximum of 6 tons. To perform the operation, you should look at the scope of your project in order to make the right choice between single-drum and double-drum rollers.
Cylinder roller (smooth wheel)
Cylinder rollers are the most common type of roller used today. These types of rollers have a traditional cylinder drum and are the most basic type of road construction rollers. Most of these rollers are single-drum rollers only, although there are often a number of rollers that use two drums. The gross weight of these bags is between 8 and 10 tons. Cylindrical rollers are also known as plain roller. These types of road construction rollers are mostly used to stabilize stone or other similar materials on flat land. Among the types of cylinder rollers, three-wheeled rollers, two-axis and three-axis tandem rollers can be mentioned. It should be said that when you use these rollers for surface roads to create a smoother and smoother surface, they provide the best performance and they should not be used for clay soils.
Vibration roller
Network roller
Grid rollers have a cylindrical heavy steel surface. This steel surface forms a grid of steel bars with square holes. Usually, the balance of this type of road construction rollers is provided by concrete blocks. This type of road roller is generally a towing device. This model of road construction rollers is generally used to increase the density of medium-graded coarse soils and weathered rocks and is often used in infrastructure and sub-base road projects.
Rubber tire roller (pneumatic)
These types of road rollers also have their drums removed from the normal cycle and instead have multiple rows of pneumatic tires close together at the front and rear of the vehicle. The tires of these types of rollers are also staggered to apply pressure across the entire width of the roller. These types of rollers are best used in soft materials and compact soils and have high efficiency. These rollers are also found in highway construction, especially when starting to smooth the bitumen on some roads. These types of road rollers may have large or small wheels, and usually the weight of these rubber tire rollers is changed by adding weight in order to make them suitable for compacted soil.
Shoemaker roller (Philly's foot)
This type of roller is similar to the footing roller, but the difference is that it is located on the roll of a steel plate machine. Flared rollers are usually very suitable for compaction of all types of soil, especially sand. Rollers with shoes, which are also called elephant feet, create less disturbance on the soil surface during soil compaction.
Roller
This type of road roller has blades that are usually rectangular and built in a relatively hexagonal pattern. Of course, some of these rollers have different shapes in different designs, however, their shape is not very important in their performance. These tamping rollers are also called ramming rollers and are usually used in projects that have to work with heavy soils such as clay. The reason why this roller is named Pachebezi is that its leveling is as if a herd of goats left traces of their feet on the ground.
