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 air compressor (15 m³/min @ 18 bar / 261 psi) onto a single self-propelled crawler chassis. Powered by a single 176 kW (240 HP) Yuchai YCA07240 diesel engine, it eliminates the need to tow a trailer compressor, cuts jobsite fuel burn by up to 25%, and avoids trailing air-hose hazards.
Features a high-strength aluminum alloy feed beam (3,590 mm advance stroke) with superior anti-torsion rigidity and reduced mast weight. The mechanized 7+1 carousel rod-handling system, with automatic thread oil injection, enables single-operator deep drilling to 24 meters using Φ64/Φ76 mm rods and 3"/4" DTH hammers.
Built on a 10,000 kg heavy-duty crawler undercarriage with 430 mm ground clearance and ±10° frame leveling for steady gradeability up to 25° across rough terrain. Powered by a high-speed rotary head (0–180 rpm, 1,560 N·m torque) and 22 kN push-pull thrust, plus an onboard hydraulic cyclonic laminar-flow dry dust collector.
*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 KD45ED introduces a mechanized 7+1 automatic carousel rod changer and an automatic thread lubrication system for fully automated rod handling. It also features a high-strength aluminum alloy feed beam, increases maximum rotation speed to 180 rpm (vs. 110 rpm), elevates ground clearance to 430 mm (vs. 330 mm), expands beam tilt angle to 147°, and increases machine weight to 10,000 kg (vs. 8,700 kg) for superior drilling stability.
A: No. The KD45ED is a fully self-contained, integrated crawler drill rig with an onboard 18-bar, two-stage screw air compressor (15 m³/min) powered directly by its 176 kW Yuchai diesel engine, operating autonomously with no trailing air hoses.
A: The aerospace-grade extruded aluminum alloy beam reduces upper mast weight while offering exceptional anti-bending and anti-torsion rigidity, significantly improving hole straightness and minimizing vibration on the feed mechanism during percussion drilling.
