The KJ311 hydraulic tunneling drilling rig (plateau type) is designed for high altitude construction. It is suitably qualified for the drilling of hard rock mine whose section falls in the range of 12－35 square meters.

Features

1. The firm flexible boom is capable of optical coverage of the section; 360° rotation and self-leveling beam make drill positioning easy.  The boom can also be used for the drilling of lateral cross-cut and rock bolting.

2. The drill rig provides a good view for the operator with a balanced layout and the articulated chassis and four-wheel drive to ensure flexible, fast and safe driving in narrow tunnels.

3. The stepped piston is used for the high-frequency impacting rock drill and this can improve the transmission efficiency of the impact wave and drilling speed and reduce the consumption of drilling tools.

4. Considerable space and automatic functions enable the driver to concentrate on drilling in a safe, fast and accurate manner.

5. All the relevant parts are kept in good protection, meanwhile maintenance easily.
