Strong 6,5 HP-Power unit with 2 Cylinder-lifting-unit HE60 put into a strong case. The hydraulic extraction devices with petrol engine made by Geotechnik-Dunkel /Nordmeyer GEOTOOL only get the best industrial engines inside. By that, the best start behavior and live time get reached. By several combinations of the power units and lifting devices lifting forces from 90 to 250 kN can be delivered and a maximum of 3 m/min.
