Installation of HDD Drillto ZT 20/32AT

A unique HDD installation for rock drilling built on the basis of the 21/32CDF installation. The powerful 133kW Cummins engine, 6000Nm torque on the outer and 2000Nm on the inner rod allow drilling in hard, rocky and frozen rocks. At the same time, the rotation speed is 300 rpm. A powerful bentonite pump with proportional control of 360 l/min with a sharp bentonite feed function perfectly washes and removes drilled soil from the well. And the small dimensions of 6600x2250x2380mm and a weight of 12,000 kg make it possible to move the installation even on a tow truck.
