Kaishan Surface Drilling Rigs/Crawler DTH Drill Rig with Integrated Air Compressor Series
KT12
The KT12 integrated surface DTH drilling rig can drill vertical, inclined and horizontal holes and is mainly used in large open-pit mines and stonework for blast holes and pre-splitting holes. A Cummins non-road diesel engine is the single power source; through two-end output it drives both the screw compressor system and the hydraulic transmission system. The rig is equipped with an automatic rod handling system, a drilling rod floating slide module, a drill pipe lubrication module, a drill pipe sticking prevention system, a hydraulic dry dust collection system and an air-conditioned cab, with optional drilling angle and depth indication. It is characterized by excellent integrity, high automation, efficient drilling, environment-friendliness, energy conservation, simple operation, flexibility and travelling safety.

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.
