These are self propelled, light in weight and compact machines having high forces, low amplitude and high frequency, based on the principle of reciprocal pressure generation by frequency un directional impulse vibrator which causes the ramming and forward movement, Sana Earth Rammer can compact thicker layers of non-cohensive and semi-cohensive soils and maximum density (95% to 98%) are achieved in less number of passes. Application non-cohesive soil, subgrades maneuvers close to abutments retaining walls, pilling , ideal for key trenches, cannel embankments, back till jobs, factory floor, foundations, bridge approaches etc.
