This compact unit is designed for dynamic probing according to DIN ISO 22476-2 and -3 (formerDIN 4094) and allows for leightweight, medium heavy and superheavy dynamic probing tests by simple drop weight mass adaption on site. Drop heights of 50 cm or 75 cm can be adjusted. Soil sampling with tube diametres up to 90 mm is ideally possible. It is mounted on a self-propelled rubber chain crawler and extremely suitable for rough terrains. Inclines of 30 degrees pose no problems, the mast can be adjusted accordingly, a waterbubble indicates the true vertical position.
