Applications


The KJ321-CYTJ45/2 hydraulic tunneling drilling rig is suitably qualified for the drilling of tunnels whose section falls in the range of 12-45 square meters, capable of drilling the blast hole and rock bolting in a vertical, inclined and horizontal way.

Features


  • The drilling rig is fitted with the flexible boom in two symmetric rectangular coordinates, without any operation blind spot. 360°rotation and self-leveling beam make drill positioning easy; it 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.
