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 the heavy DTH percussion drilling system and an onboard two-stage screw air compressor (18 m³/min @ 20 bar / 290 psi) onto a single crawler chassis. Driven by a 242 kW (325 HP) Cummins QSL8.9 diesel engine via dual-terminal flywheel and PTO outputs, it eliminates trailing air hoses and cuts jobsite diesel fuel burn by up to 25%.
Equipped with a powerful feed mechanism delivering 40 kN propelling force and 4,490 mm feed stroke. The automated 7+1 rod carousel, floating slide plate, automatic thread lubrication module, and electro-hydraulic anti-jamming system allow safe, single-operator deep blast-hole drilling down to 32 meters with Φ64/Φ76 mm rods.
Outfitted with an enclosed, climate-controlled operator cabin meeting international FOPS & ROPS safety certifications with low interior noise below 85 dB(A). Built on a reinforced 17,000 kg crawler undercarriage with 420 mm ground clearance and ±10° track oscillation, delivering exceptional stability on 25° quarry slopes.
*Note: Due to continuous technical updates and improvements, any differences between parameters/configurations and actual products are subject to the delivered machine; additionally, machines shown in images may include optional equipment.

A: The KT11 integrates the crawler drill chassis and a 20-bar two-stage screw compressor powered by a single 242 kW Cummins engine. This all-in-one architecture eliminates trailer compressor towing, reduces overall jobsite diesel consumption by up to 25%, reduces operating personnel from two workers to one, and completely removes high-pressure rubber hose dragging hazards across jagged rock benches.
A: No. The KT11 is 100% self-contained. The 242 kW Cummins diesel engine powers all hydraulic positioning, tramming, and rotation systems while directly driving the onboard 20-bar two-stage screw compressor, operating completely autonomously with zero trailing air hoses.
A: Yes. The heavy-duty articulated drill boom offers versatile angular positioning: lifting from up 47° to down 20°, boom swing from right 50° to left 15°, carriage swing from right 96° to left 30°, and beam tilt angle of 114°, allowing efficient drilling of vertical, inclined pre-split, and horizontal toe holes.
