KJ211 Underground Mining Drill Rigs and Tunneling Jumbo is designed for mining, preparation and tunneling. As a hydraulic rock-drilling jumbo with independent operation, it can drill vertical, inclined and horizontal blast holes; applicable to the hard rock tunneling with a section of 12-35m2.
Its firm and reliable universal big arm has the best shape of section coverage, boosting the 360° overturn and automatic leveling of the beam for rapid and convenient borehole positioning. The big arm can also be used for lateral cross hole opening and anchor rod boring operations.
The arrangement of the jumbo ensures the good view of the operator.
Evenly-arranged and powerful 4-wheel drive hinge chassis ensures flexible, quick and safe driving in a narrow roadway.
The high-frequency percussion rock driller uses the cascaded piston to optimize the efficiency of shock wave transmission, raise the drilling speed, reduce clamping bit consumption and enhance the soundness of device.
The big space of operation and a series of automatic functions can help the driver to concentrate their attention to safe, rapid and accurate tunneling.
All its repair and maintenance parts have been protected well, and its repair and maintenance are easy.
