What Is Sheepsfoot Roller | Advantage & Disadvantges of Sheepsfoot Roller | Application of Sheepsfoot Roller | Design of Sheepsfoot Rollers

Sheepsfoot Roller:

The sheeps foot compactor, also known as sheep foot roller is used for compacting, tamping rollers or padfoot rollers, which have many rectangular-shaped lugs or feet.

In road construction works the sheep foot roller used for compacting soil and silty clay.

What Is Sheepsfoot Roller?

The sheepsfoot roller compactor, known as sheepsfoot rollers, are of a vibration and static type roller for compaction of soil with a mixture of all fine-grained clay and sand-gravel.

Sheep foot roller is also known as tamping rollers or pad foot rollers, which have many rectangular-shaped lugs or feet.

In road construction works the sheep foot roller is very good for compacting soil and silty clay.

The resulting compaction of such soils by sheepsfoot roller is probably well for other types of machinery at low moisture content soil.

For protruding studs on the drum, similar to a sheet foot roller, it provides a kneading action.

For cohesive soil, the sheep foot roller is mostly used. For sandy soils, such as heavy clays and silty clays except.

By filling the drum with wet some other material or sand, the sheepsfoot packer or sheep foot roller pressure on the feet may be increased.

They depend on the specification of various manufacturers the teeth size slightly different from one sheep foot to another sheep foot.

In the sheep roller, known as sheep foot roller, to provide pinpoint pressure all across the soil, it has an almost hoof-like structure protruding from a roller.

Characteristics of Sheepsfoot Roller:

1. The sheep foot compactor or sheep foot roller generated pressure up to 1400 to 7000 mph and the speeds of work normally range from 6-10 km/h.
2. The total covered area by the sheep foot roller is less when it compacts the soil. Just 8-12 % ground coverage under the lugs on the drum by the sheep foot rollers.
3. A sheep foot roller compacting effort depends on the kneading and static weight.
4. For cohesive soil, the sheep foot roller is mostly used. For sandy soils, such as heavy clays and silty clays except.
5. By filling the drum with wet some other material or sand, the sheep foot roller pressure on the feet may be increased.
6. The layer thickness of the compacting soil should be a minimum of 50 mm or more, which depends on the length of the foot.

Advantages of Sheepsfoot Roller:

The advantages of sheepsfoot roller are as follows.

1. Sheep foot roller is also known as tamping rollers or pad foot rollers, which have many rectangular-shaped lugs or feet.
2. The advantage of a sheep foot roller is, In road construction works the sheep foot roller is very good for compacting plastic soil like silty clay.
3. The advantage of the sheep foot roller is it can be used as a vibration and static type roller for compaction of soil with a mixture of all fine-grained clay and sand-gravel.
4. The common advantage of sheep foot roller is, it is mostly used for cohesive soil. For sandy soils, such as heavy clays and silty clays except.
5. The part of the soil layer can be compact by the sheep foot roller, The soil layer should be a minimum of 50mm or more, which depends on the length of the foot it is another advantage of sheep foot roller.
6. From the bottom of each lift to the top the sheep foot roller compact as well. As like there are many more advantages of sheep foot roller.
7. In cohesive soil or silty soil where the other roller does not work properly and where the job is done immediately, there the sheep foot roller is used.
8. Another advantage of sheep foot roller is, nowadays the contactors are used as various soil and aggregate compactors.
9. More advantage of sheep foot roller is it can compact the soil with high-speed compaction.
10. The sheep foot roller we can Also, use for compaction in dams, road construction work, and pavements.
11. By the sheep foot roller, we can use it to compact soil at greater depths.
12. when filling trenches in a narrow space as it gives yet another ability to control. That is the advantage of the sheep foot roller.

Disadvantages of Sheepsfoot Roller:

Like the above advantage, the sheep foot roller has many disadvantages that are are below –

1. The disadvantages of sheep foot rollers are, In wet conditions, the sheep foot roller is used frequently.
2. The layer thickness of the compacting soil should not be less than the minimum of 50mm, which depends on the length of the foot. This is a disadvantage of sheep foot rollers.
3. The disadvantages of the sheep foot roller are its drum should be filled with some wet external materials or sand to increase the compaction pressure of the roller.
4. When we use a sheep foot roller an experienced driver is required to control the sheep foot roller. This is a high disadvantage of a sheep foot roller.
