Features


  • Complete functions. The advancing beam at two stations is available and it is equipped with a magazine having a storage capacity of 10 bolting rods, along with optional protective netting module; it is capable of performing the following tasks: drilling, netting and installation of rock bolting rod;
  • High safety. Operators are protected by the ceiling, far away from the danger area;
  • High efficiency. The stepped piston is used for the high-frequency rock drill and this can improve the transmission efficiency of impact wave and improve drilling speed and reduce the consumption of drilling tools and make it in good condition;
  • The drill rig provides a good view for the operator; the articulated chassis of four-wheel drive ensures the flexible, quick and safe driving in the narrow tunnel;
  • 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, also easy to maintain.
