KJ211-CYTJ45(C) hydraulic tunneling drilling rig used for mining preparations and tunneling, it is an independent working drill rig. It can be used for drilling vertical, inclined and horizontal blast hole, suitable for the hard-rock of any section in the range of 7-25m2.


  • 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.
