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 unidirectional impulse vibrator which causes the ramming and forward movement. Kieng  Earth Rammer can compact thicker layers of non-cohesive and semi-cohesive soils and maximum protector density (95% to 98%) are archived in less numbers of passes application non-n cohesive soil, subgrades,maneuvers close to abutments retaining walls, pilling, ideal for key trenches, cannel embankments, back fill jobs, factory floor, foundations, bridge approaches etc.
