The kit

摘要

The GRUNDOMAT N is self-propelled using compressed air and a two stroke impact method. Whilst in operation should an obstacle be encountered and forward propulsion hindered, the crowned reciprocating head will continue chiselling independently; until the obstruction is fragmented and displaced. This design drives the percussive Grundomat mole fast and accurately through the ground, displacing and compacting the soil, whilst at the same time forming a bore hole through which pipes and cables can be pulled in simultaneously. The GRUNDOMAT N has a triple gear control stud, with the frequency and speed of the striking impact being chosen via two forward gears.
