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 percussion rock drilling and an onboard two-stage screw compressor (15 m³/min @ 18 bar / 261 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 avoids trailing air-hose hazards.
Upgraded with a high-torque rotary head delivering 2,000 N·m maximum torque and 25,000 N (25 kN) push-pull feed force, expanding borehole coverage up to 127 mm. Features an articulated boom with 125° beam tilt, 79° carriage swing, and a 900 mm compensation stroke for versatile vertical, inclined, and low horizontal toe-hole blasting.
Built on an 8,600 kg heavy-duty crawler undercarriage with dual-speed tramming motors (2.5/4 km/h), 330 mm ground clearance, and ±10° hydraulic frame levelling for steady gradeability up to 25° on rugged quarry benches. Outfitted with an onboard, hydraulic-driven cyclonic laminar-flow dry dust collection system for clean, eco-compliant operations.

A: The KD40E upgrades the onboard two-stage screw compressor to 15 m³/min @ 18 bar (versus 12 m³/min @ 15 bar on KD35E), increases maximum rotary torque to 2,000 N·m (versus 1,680 N·m), expands borehole diameter up to 127 mm (versus 115 mm), enhances frame leveling to ±10° (up 10°, down 10°), and increases machine operating weight to 8,600 kg for superior drilling stability in hard rock.
A: No. The KD40E is an all-in-one integrated crawler drill rig with an onboard 18-bar, two-stage screw air compressor driven directly by its 162 kW Yuchai diesel engine, operating autonomously with no trailing air hoses.
A: Yes. The heavy articulated drill boom offers extensive angular positioning: 125° beam tilt, carriage swing from left 39° to right 40°, boom swing from left 44° to right 39°, and lifting angles from up 50° to down 25°, enabling versatile drilling of vertical blast holes, inclined pre-split holes, and horizontal toe holes.
