KJ311
12-35m 2KJ311 hydraulic tunneling drlling rig is suitably qualified for the drlling of hard rock mine whose section fals in the range of 12-35 squaremeters
360°;
The firm flexible boom is capable of optical coverage of the section: 360° rotation and self-eveling beam make drill positioning easy.It can also be used for the drilling of lateral cross-cut and rock bolt:
The dril rig provides a good view for the operator, balanced layout and the articulated chassis of four-wheel drive ensure the flexiblefast and safe driving in the narrow tunnel:
The stepped piston is used for the high-frequency impacting rock dril and this can improve the tranmission efficiency of impact waveand drilling speed and reduce the consumption of drilling tools and make it in good condition;
Rod sizeConsiderable space and automatic functions enable the driver to concentrate on driling in a safe. fast and accurate manner.,;
All the relevant parts are kept in good protection, meanwhile maintenance easily.
