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
Integrates a heavy-duty two-stage rotary screw compressor delivering 13 m³/min at 18 bar (261 psi). Powered by a single 162 kW Yuchai 6-cylinder diesel engine, eliminating separate compressor towing and cutting total fuel burn by up to 30%.
Equipped with an automated mechanical pipe carousel storing 7+1 rods (Φ64×3000 mm), hydraulic breakout tongs, and automatic thread oil injection. Enables single-operator drilling down to 24 meters with zero manual rod lifting.
Features an integrated hydraulically driven cyclonic laminar flow dust extraction system. Captures cuttings and fine silica dust directly at the borehole collar to protect engine filtration and satisfy green quarry mandates.
Boasts 147° beam tilt, 105° carriage swing, and ±10° hydraulic frame levelling on heavy crawler tracks. Easily navigates rugged quarry slopes (≤25°) to drill vertical blast holes, inclined pre-splitting, and horizontal toe holes.
