  • Drilling depth:30m

  • Total Power:195KW

  • Dimensions (L×W×H):8000×2260×2800mm

Applied range:

It can drill vertical, inclined and horizontal holes, used for drilling and pre-splitting holes in open pit mines and stone works, etc.


Module integration for ease of use

drilling equipment integrating down-the-hole drilling system and screw air compressor system.

Well-integrated and powerful

It is of compact structure, well integrated and easy to move and its two systems are powered by a diesel engine with six cylinders.

high air pressure screw compressor head

Its high air pressure screw compressor head product and single stage compression adopts internationally advanced Tangshi Y-line to produce high flow (13m³/min) and high air pressure (1.7MPa).

high working efficiency

provides strong power for high pressure pneumatic hammer and its drilling speed is 20%-50% higher than that of medium Working pressure drilling rig.
