KJ212 Tunnel Jumbo Drilling Rig

Features:

KJ212 hydraulic tunneling drilling rig used to drill vertical, inclined and horizontal blast holes in low tunnels. Through the section (2.5m*1.5m), the drill rig is suitably qualified for any tunnels whose section falls in the range of 3.5m*1.8m-5m*4.8m.

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;

The drill rig provides a good view for the operator;

Balanced layout and the articulated chassis of four-wheel drive ensure the flexible, fast and safe driving in the narrow tunnel;

The stepped piston is used for the high-frequency impacting rock drill and this can improve the transmission efficiency of impact wave and drilling speed and reduce the consumption of drilling tools and make it in good condition;

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

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