AZT2-9700 hydraulic tunneling drilling rig is suitably qualified for the drilling of tunnels whose section falls in the range of 16-95 square meters, capable of drilling the blast hole and rock bolt in a vertical, inclined and horizontal way.

The drill rig is fitted with the flexible boom in two symmetric rectangular coordinates, without any operation blind spot. 360° rotation and self-leveling beam make drill positioning easy; it can also be used for the drilling of lateral cross-cut and rock bolting. The drilling rig provides a good view for the operator; balanced layout and the articulated chassis of four-wheel drive ensure flexible, fast and safe driving in narrow tunnels.

The stepped piston is used for the high-frequency impacting rock drill, which improves the transmission efficiency of the impact wave and drilling speed, reduces the consumption of drilling tools, and maintains overall system durability. Considerable space and automatic functions enable the driver to concentrate on drilling in a safe, fast, and accurate manner. All relevant parts are well-protected while allowing easy maintenance.
