For maximum off-road capability in poor ground conditions Foundation & Exploration Services has mounted a Knebel HY77 electro hydraulic drill rig on a Mercedes Benz Unimog. Renowned for its ability to cope with all types of ground conditions, the Unimog has a maximum road speed of 90kph. This combination has resulted in a completely selfcontained unit with mud, water and foam pumps, able to undertake a variety of drilling techniques without the need for support vehicles.
