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 high-capacity two-stage screw compressor (22 m³/min @ 24 bar / 348 psi) on a single crawler platform. Driven by a 298 kW (400 HP) Cummins QSZ13-C400 diesel engine via dual-terminal outputs driving variable hydraulic systems, eliminating trailing air hoses and reducing mine fuel burn by up to 25%.
Features a high-strength aluminum alloy feed beam delivering 65 kN maximum feed force and 4,100 N·m torque for 4″/5″/6″ DTH hammers. The automated carousel (8+1 or 6+1 for Φ89/Φ102 mm rods), floating joint thread protection, and digital angle/depth display allow precision single-operator drilling down to 36 meters.
Built on a reinforced 24,800 kg crawler undercarriage with 140 kN heavy traction, 430 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 KT15C is Kaishan's heavy mining flagship model, upgrading engine displacement to a 13-liter Cummins QSZ13 (298 kW vs. 264 kW), boosting screw compressor delivery to 22 m³/min @ 24 bar (vs. 20 m³/min @ 22 bar), expanding borehole diameter up to 190 mm (vs. 152 mm), increasing maximum feed thrust to 65 kN (vs. 40 kN), and featuring automated handling for larger Φ89/Φ102 mm drill pipes up to 5 meters in length.
A: Yes. The KT15C comes equipped with an integrated real-time digital drilling display system inside the cabin that monitors drilling angle and borehole depth with high accuracy, ensuring precise explosive charging and optimal rock fragmentation.
A: No. The KT15C is completely self-contained. The 298 kW Cummins engine drives both the heavy variable hydraulic system and the onboard 24-bar screw compressor, eliminating external tow-behind compressors and trailing hoses completely.
