KJ311 Double Layer Bean Type,Tunnel Jumbo Drilling Rig
Features:
KJ311 Hydraulic Tunneling Drilling Rig(Double Layer Beam Type) is suitably qualified for the drilling of hard rock mine whose section falls in the range of
12-35 square meters. It is specially designed for the rock bolt and is capable of drilling the 2.2-meter-deep rock bolt in the 4-meter-high tunnel.
The firm flexible boom is capable of optical coverage of the section; 360° rotation and self-leveling beam make drill positioning easy;The arm 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 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.
