KAISHAN DRILLING

Kaishan Surface Drilling Rigs/Crawler DTH Drill Rig with Integrated Air Compressor Series

KT9C

The KT9C integrated surface DTH drilling rig integrates the down-the-hole drilling system and the screw air compressor system in one machine. It can drill vertical, inclined and horizontal holes and is mainly used in open-pit mines and stonework for blast holes and pre-splitting holes. It uses a larger Yuchai non-road diesel engine and a two-stage screw compressor with a hydraulic dry dust collection system, and is intended for larger hole diameters.

Overview

The KT9C integrated surface DTH drilling rig integrates the down-the-hole drilling system and the screw air compressor system in one machine. It can drill vertical, inclined and horizontal holes and is mainly used in open-pit mines and stonework for blast holes and pre-splitting holes. It uses a larger Yuchai non-road diesel engine and a two-stage screw compressor with a hydraulic dry dust collection system, and is intended for larger hole diameters.

Key highlights

  • ✓Single diesel engine drives both the on-board screw compressor and the hydraulic transmission system through two-end output.
  • ✓Integrated rig: the on-board screw compressor supplies the drilling air, no separate air compressor is needed on site.
  • ✓Automatic rod handling system and drill rod lubrication module.
  • ✓Hydraulic dry dust collection system; wet dust collection available as an option on larger models.
  • ✓Automatic or electro-hydraulic anti-jamming control depending on model.
  • ✓ROPS & FOPS protected cab with air-conditioning.
  • ✓Capable of drilling vertical, inclined and horizontal holes.

Applications: Used in open-pit mines and stonework for blast holes and pre-splitting holes.

Recommended packages

Air compressor match

Integrated rig — the screw air compressor is built into the machine, so no separate compressor unit is needed. Only confirm the onboard compressor rating (pressure and flow) matches your hammer size.

DTH hammer & bits

Match the DTH hammer class to your hole diameter: K3/K30C for 90-105 mm, K5/K50 for 135-165 mm — see the DTH hammer series page for the full ladder.
