KJ311 hydraulic tunneling drilling rig is suitably qualified for the drilling of hard rock mine whose section falls in the range of 12-35 square meters.

KJ311 hydraulic tunneling drilling rig is suitably qualified for the drilling of hard rock mine whose section falls in the range of 12-35 square meters.

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

● 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.

Kaishan LGCY Screw Air Compresso Kaishan LGCY Screw Air Compresso
Diesel portable screw air compressor is widely applied in the industries, such as, road, railway, mine, water conservancy, shipbuilding, urban construction, energy and war industry, etc.
High Pressure DTH Drill Bit for High Pressure DTH Drill Bit for
DTH (Down to Hole) drill bit, also called spline connected drill bit, is mainly used in large scale mine (open and underground), open quarry and construction. The hammer is situated down the hole in direct connected with the drill bit with splines in the bit. The hammer piston strikes the drill bit resulting in an efficient transmission of the impact energy and insignificant power losses with the hole depth.
