Suitable, for instance, for trench sheeting, light-weight sections, sheet-pile walls, wide I-shaped structural steel beams and soil compaction. Driven by on-board hydraulics – hydrolic self-synchronisation – integrated vibration absorber – low height, low center of gravity – self-acting rotational swiveling – free to float – additional static pressure forces through the excavator boom increase ramming power – with compacting plate also usable as high performance vibrator.
