Sheepsfoot Roller

The sheepsfoot roller is a self propelled heavy machinery which is used throughout the world as a compaction device. Protruding studs on the drum is similar to a sheepsfoot, which provides a kneading action. For compaction of plastic soils like clay or silt it is very effective. On granular materials, sheepsfoot rollers tend to shove rather than compact such soils. Sheepsfoot roller is available in variety of sizes depending on the nature of the soils.

Mechanical Operations
The sheepsfoot roller works very well on cohesive soils. At low moisture contents the resulting compaction of such soils by sheepsfoot roller is probably better than other types of machinery. In wet conditions they are used infrequently. The sheepsfoot compacts, from the bottom of each lift to the top.

The high contact pressures compact the soil directly beneath the foot tip. The tamping foot roller combines the advantages of both the sheepsfoot and steel wheel. Like the sheepsfoot roller, it compacts from the bottom to the top of the lift for uniform density and like the steel wheel, it compacts from the top of the lift. The tamping foot roller is capable of high rolling speeds without throwing material because of the design profile of the tamping foot.

Due to this compaction speed and the pressure applied on the soils sheepsfoot roller is very useful in the construction of both small and big dams.
