The drilling rig is designed to be mounted on a vehicle with a GVM over 3.5 tons. As a result, the drilling rig can be equipped with a heavier, but more powerful 42 kW diesel engine, which is the source of the hydraulic pump drive that can power devices mounted on the machine, such as: a cutter, pipe clamp, winch or geological probe. In addition, the drilling rig has a larger mast, which allows the use of long augers.
