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 (20 m³/min @ 22 bar / 319 psi) onto a single self-propelled crawler chassis. Powered by a high-output 295 kW (400 HP) Yuchai YCK09400 diesel engine with dual-terminal outputs, it eliminates the need to tow a trailer compressor, reduces jobsite fuel burn by up to 25%, and avoids trailing air-hose hazards.
Equipped with an automated 7+1 carousel rod-handling system, automatic thread oiling, and anti-jamming protection for single-operator deep drilling to 24 meters. Powered by a heavy-duty rotary head delivering 4,000 N·m maximum torque and 25 kN feed force, optimised for 5-inch DTH hammers across large 115–165 mm blast holes.
Built on a 13,000 kg heavy-duty crawler undercarriage with 430 mm ground clearance and ±10° hydraulic frame levelling for steady gradeability up to 25°. Features an innovative dual-hinge articulated carriage swing mechanism (Hinge 1: R48°/L47°, Hinge 2: R92°/L3°) and an onboard hydraulic cyclonic dry dust collector capturing over 99% of airborne mineral dust directly at the hole collar.

A: The KD55ED integrates a mechanised 7+1 automatic carousel rod changer and an automatic thread lubrication module for single-operator automated pipe changeout. It also increases operating machine weight to 13,000 kg (versus 12,100 kg on KD55E) for maximum drilling stability and features an expanded dual-hinge carriage swing mechanism for superior multi-angle bench positioning reach.
A: No. The KD55ED is a 100% self-contained, integrated crawler drill rig with an onboard 22-bar, two-stage screw air compressor (20 m³/min) powered directly by its 295 kW Yuchai diesel engine, operating autonomously with no trailing air hoses.
A: The KD55ED is factory-optimised for 5-inch high-pressure DTH hammers and Φ76 mm × 3,000 mm friction-welded drill pipes, delivering exceptional energy transfer and penetration rates in hard rock formations up to f=20.
