This machine is unprecedentedly good that is turned out based on previous experiences, making it an extraordinary choice for operators working in large-scale open-pit mines. The drilling machine is driven by a powerful engine that activates the interior hydraulic movement system, high-pressure air end and DHT hammer, through which it can drill rocks efficiently, change angles and move smoothly. The machine is equipped with several advanced modules, such as a hydraulic dust collector that can reduce harm to environment, a hands-free hydraulic rod handling module, a floating rig joint protecting rod thread and an anti-jamming module. With these features, the machine can be operated by one person. It also provides a cozy working environment for operators, with an air-conditioner installed in its large cab.

  • Integrated Surface DTH Drilling Rig, KT20
Features
  • A disc-like rod handling system, by which the rod can reach as deep as 36 meters.
  • Carriage’swing angle is as wide as 130°, with the right side being 97° and the left, 33°. It can drill a horizontal hole and a vertical hole without changing the pivot. The height of the horizontal hole ranges from 550-4200 mm.
  • A Caterpillar engine is equipped, delivering powerful and stable performance.
  • A two-terminal engine is used, which is compact and easy to fix.
  • DHT hammer works very well since an air compressor is installed that delivers fresh air at 22m³/min and 350 psi.
  • Automatic leveling of the track guarantees the stability of the machine in different terrain.
  • Dual rotary drills prevent deflection when drilling.
  • Hydraulic and electronic components are all imports.
