    Performance Characteristics
    Complete functions. The beam have two working stations and it is equipped with a magazine having a storage capacity of 10 rock bolt 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, thus making maintenance easy.
