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
Powered by a single 295 kW (400 HP) Yuchai YCK09400 diesel engine utilizing dual-terminal output to simultaneously drive the hydraulic system and an onboard two-stage rotary screw compressor (20 m³/min @ 22 bar / 319 psi). Eliminates auxiliary compressor towing and reduces jobsite diesel consumption by up to 30%.
Features an automated pipe-handling carousel storing 7+1 drill rods (Φ76×3000 mm), hydraulic breakout cylinder, automatic thread lubrication, and an intelligent anti-sticking system. Automatically adjusts feed and rotation when encountering fractures, enabling safe, single-operator drilling down to 24 meters.
Equipped with an advanced dual-hinge carriage swing mechanism (Hinge 1: Right 48°/Left 47°; Hinge 2: Right 92°/Left 3°) and 4,000 N·m rotary torque. The heavy 13,000 kg chassis features 430 mm ground clearance, dual-speed travel, ±10° frame leveling, and a dry cyclonic dust collector for 25° slope stability.
