Kaishan DTH Drilling Rigs
Heavy-duty surface crawlers and integrated rigs for open-pit mining, quarry blasting, and slope stabilization. High penetration rate and anti-jamming hydraulic system.
EQUIPMENT CATEGORIES
Combines heavy DTH mining percussion drilling with an onboard giant two-stage screw air compressor (31 m³/min @ 25 bar / 363 psi) on a single crawler platform. Driven by a 372 kW (500 HP) Cummins QSZ13-500 diesel engine via dual-terminal outputs, it eliminates trailing air hoses and cuts quarry diesel fuel burn by up to 25%.
Delivers an extraordinary 6,100 N·m rotary torque and 65 kN feed force for 5″/6″ DTH hammers in large 152–203 mm blast holes. The automated carousel for heavy Φ102/Φ114/Φ127 mm rods (5m/6m length), floating joint thread protection, and digital display allow precision single-operator drilling down to 36 meters.
Built on a reinforced 28,100 kg crawler undercarriage with 410 mm ground clearance and ±10° frame leveling for 25° gradeability. Features a fully enclosed, climate-controlled operator cab certified to international FOPS & ROPS safety standards with dry cyclonic laminar flow dust extraction.

A: The KT25 is Kaishan's largest super-heavy surface DTH rig, upgrading diesel engine power to 372 kW / 500 HP (vs. 298 kW on KT15C), increasing compressor delivery to 31 m³/min @ 25 bar (vs. 22 m³/min @ 24 bar), expanding maximum hole diameter to 203 mm / 8 inches (vs. 190 mm), boosting rotary torque to 6,100 N·m (vs. 4,100 N·m), handling larger Φ102/Φ114/Φ127 mm rods up to 6 meters in length, and increasing machine weight to 28,100 kg for rock-solid drilling stability.
A: Yes. The KT25 features an automated carousel system configured for either 6+1 (5-meter rods) or 5+1 (6-meter rods) with diameters of Φ102, Φ114, or Φ127 mm, coupled with mechanical floating thread protection, automatic oil injection, and anti-sticking electro-hydraulic control for continuous single-operator drilling down to 36 meters.
A: No. The KT25 is completely self-contained. The 372 kW Cummins diesel engine powers all hydraulic positioning, feed, and tramming systems while directly driving the onboard 25-bar two-stage screw compressor, operating completely autonomously with zero trailing air hoses.
