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
Equipped with high-performance hydraulic drifter options (HC50 / HC95 / YYG18U / HC95LMH / YYG22U) delivering 13–22 kW impact power at 53–62 Hz. The advanced stepped piston design optimizes shockwave transmission efficiency, accelerates penetration rates, reduces consumable rod wear, and enhances overall equipment availability.
Features a heavy-duty K 22 universal drill boom with 800 mm telescopic extension, 1600 mm feed extension, 360° beam rollover, and automatic hydraulic parallelism. Provides optimum cross-sectional coverage for headings between 7–25 m² and easily adapts to cross-cut face drilling and roof bolting operations.
Built on a compact 1600 mm wide articulated 4WD carrier powered by a Cummins B3.9CS4-80C diesel engine (59 kW) for agile narrow-vein tramming, paired with a 45/55/75 kW electro-hydraulic power pack for zero-emission underground drilling, enclosed wet multi-disc brakes, and a hydraulic telescopic FOPS & ROPS safety canopy.

*Note: Technical specifications are subject to continuous improvement without prior notice. Custom OEM/ODM configurations, drifter selections (HC50 / HC95 / YYG18U / YYG22U), and tailored underground electrical voltages are available upon request for bulk orders.
The Kaishan KJ211 hydraulic underground mining jumbo is specifically engineered for high-speed drifting, tunneling, and production preparation across medium-to-hard rock headings (7–25 m²):
The KJ211 is optimized for underground tunnel cross-sections from 7 m² to 25 m², with automatic hydraulic self-leveling coverage of 5000 mm width × 4200 mm height and extended manual leveling reach of 5800 mm width × 4950 mm height.
Customers can choose from multiple drifter models, including HC50 (13 kW, Φ32–76 mm), HC95 / YYG18U (18–20 kW, Φ42–89 mm), or HC95LMH / YYG22U (21–22 kW, Φ42–102 mm). The electric-hydraulic power pack can be configured with 45 kW, 55 kW, or 75 kW electric motors depending on the chosen rock drill and site voltage (380V/50Hz standard; custom voltages available).
