The torque generated by engine or electric motor is transferred to reciprocating motion by crank gear, which will pass it on vibrating foot through spring cylinder. It has strong impact force though it is small and light.
Tamping rammer is specifically designed for tough rammer applications in confined area, trench work, backfill and repairing work on asphalt.
Tamping rammer is suitable especially for compacting the roadbed with low water content that heavy compactor could not work.
Tamping rammer is suitable for compact the Cohesive soils--clay is cohesive; its particles stick together. Therefore, a machine with a high impact force is required to ram the soil and force the air out, arranging the particles. A rammer is the best choice
