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 (39 m³/min @ 25 bar / 363 psi) on a single crawler platform. Driven by a 563 kW (755 HP) Cummins QSM15 diesel engine via dual-terminal outputs, it eliminates trailing air hoses and cuts quarry diesel fuel burn by up to 25%.
Engineered for large 195–254 mm (up to 10-inch) blast holes, featuring an aluminum guide rail with a 9,550 mm feed stroke for Φ140 × 9,000 mm long drill rods, drastically reducing pipe changes. Delivering 6,100 N·m rotary torque and 70 kN feed thrust, it powers 8-inch (K8) DTH hammers with real-time digital angle and depth monitoring.
Governed by an advanced all-electric control system offering high sensitivity and effortless joystick operation inside a climate-controlled FOPS & ROPS safety cabin. Built on a reinforced 33,930 kg crawler undercarriage with 430 mm ground clearance and ±10° frame leveling for 25° gradeability across ultra-large open-pit mines.

A: The KT30 is Kaishan's ultimate heavy-duty flagship model, upgrading engine output to 563 kW / 755 HP (vs. 372 kW on KT25), boosting screw compressor delivery to 39 m³/min @ 25 bar (vs. 31 m³/min @ 25 bar), expanding maximum hole diameter to 254 mm / 10 inches (vs. 203 mm), increasing maximum feed force to 70 kN (vs. 65 kN), utilizing 9-meter long Φ140 mm rods with a 9,550 mm stroke to minimize rod changes, and increasing machine weight to 33,930 kg for maximum operational stability.
A: The entire machine is governed by an advanced electro-hydraulic system featuring proportional pilot joysticks and automated anti-sticking valves. This reduces operator physical fatigue, improves control responsiveness, and automatically regulates feed and rotation parameters when crossing variable rock strata.
A: No. The KT30 is 100% self-contained. The 563 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.
