Pneumatic Drill Rig HQZ260L
Two undercarriages to choose from: rubber tracks with 76 kW or steel tracks with 77.3 kW. Both versions drill to 260 m, at diameters from 130 to 305 mm.
The choice of undercarriage determines the weight. On rubber tracks the rig weighs 4800 kg and carries a Yunnei engine, on steel tracks 6000 kg and a Yuchai engine. Hole diameters reach further than on the smaller rigs of the series, up to 305 mm.
Two hydraulic motors drive the rotary head, regulated through a quick-shift valve. Working pressure runs between 1.7 and 3 MPa, and lifting capacity is 17 t. The machine is built for hard ground such as rock and concrete.
