The mast is used to rinse wellpoints into the ground with water using a telescopic rod. The drill is equipped with two manual gears to overcome the harder layers of the ground. The mast also has the option of rotary drilling with a screw auger dry or in the CFA method – the maximum diameter of the auger is 400 mm. The machine is designed to be connected to excavators with a minimum weight of 6 tons.
