KL511 hydraulic drilling rig for open use is fitted with the standard drill rod whose diameter reaches 45/51mm, which is capable of drilling vertical, inclined and horizontal blast holes in the range of 76 - 127mm. It has a wide range of applications in cutting excavation, pipelining, foundation and open-pit mine drilling.


  • Track component


  • Drill arm component


  • Cab


  • Imported full hydraulic rock drill



  • The KL511 drilling rig is equipped with a heavy-duty hydraulic top hammer rock drill (23.4KW). With powerful rotary toque, shock power, adequate hole flushing and advanced control system, make it perfectly capable drilling in complex rock conditions;

  • The frame of the drill rig is capable of  rotating in the range of 0 - 180°. In this way, the drill rig can cover 26.5 square meters with one single positioning, which can considerably improve the efficiency of hole arrangement and its response to complex conditions.

  • The drill rig is fitted with the efficient Kaishan screw air compressor. Characterized by energy conservation and environmental protection,it owns the complete proprietary intellectual property.

  • The power unit is placed at the end of the upper rotary rack, symmetric with drill boom and advancing beam. It is capable of producing an effect of counterbalance, wherever the drill boom and advancing beam are placed.

  • The travelling of drill rig, track leveling and the optional remote control of frame rotation can be operated outside the cab.
