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 screw compressor (12 m³/min @ 15 bar / 218 psi) onto a single self-propelled crawler chassis. Powered by a single 162 kW (220 HP) Yuchai YC6J220 diesel engine, it eliminates the need to tow a trailer compressor, reduces jobsite diesel burn by up to 25%, and removes hazardous trailing air hoses.
Features a heavy-duty feed mast delivering 25,000 N (25 kN) push-pull thrust and 1,680 N·m rotary torque for smooth 3-meter single-pass drilling with Φ64 mm rods. An articulated boom with 125° beam tilt, 94° carriage swing (±47°), and 900 mm compensation stroke allows flexible vertical, inclined, and low horizontal toe-hole blasting.
Built on a robust 8,000 kg crawler undercarriage with 430 mm ground clearance and hydraulic frame leveling (up to 10°, down to 9°) for steady tramming at 0–4 km/h across ≤25° quarry inclines. Outfitted with an onboard, hydraulic-driven cyclonic laminar-flow dry dust collection system for clean, eco-compliant open-pit operations.

A: No. The KD35E is an all-in-one integrated crawler drill rig with an onboard two-stage screw air compressor (12 m³/min @ 15 bar) driven directly by its 162 kW Yuchai diesel engine, operating completely autonomously with zero trailing air hoses.
A: The KD35E is an integrated rig carrying its own onboard 15-bar screw compressor with a powerful 162 kW engine (8,000 kg total weight), while the KD35S is a split crawler rig (4,400 kg) powered by a 59 kW engine that requires an external portable compressor connected via an air supply hose.
A: Yes. The heavy articulated drill boom offers extensive angular positioning: 125° beam tilt, 94° carriage swing (±47°), and wide boom lifting angles, enabling precision drilling of vertical blast holes, inclined pre-split holes, and horizontal toe holes.
