  • CYTJ45B hydraulic tunnelling driling rig used to drill vertical,inclined and horizontal blast holes in low tunnels.Through the section(2.5m*1.5m),the drill rig is suitably qualified for any tunnels whosesection falls in the range of 3.5m*1.8m-5m*4.8m.
    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 boling;
    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.
