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 a robust K 26F self-leveling universal drill boom featuring 1200 mm boom extension, 1600 mm feed extension, and 360° beam rotation. Delivers optimal face coverage (automatic leveling up to 6462×5355 mm; manual leveling up to 7250×6120 mm) for vertical, inclined, horizontal, crosscut, and rock-bolt drilling across 12–35 m² hard-rock tunnels.
Supports multiple high-frequency hydraulic rock drills (HC50 / HC95 / YYG18U / HC95LMH / YYG22U) delivering 13–22 kW impact power at 53–62 Hz for Φ32–102 mm blast holes. A 75 kW star-triangle electric hydraulic power unit drives axial variable-displacement piston pumps for rapid penetration and low drill steel wear.
Built on a balanced 13,500 kg chassis powered by a Cummins B3.9CS4-80C diesel engine (59 kW at 2500 rpm) with 20° climbing capacity, ±40° steering, ±10° rear axle oscillation, two-circuit hydraulic travelling brakes, reducer wet multidisc parking brakes, and a certified FOPS & ROPS lifting safety roof.

The Kaishan KJ310 hydraulic underground mining jumbo is purpose-built for medium-to-large hard rock tunneling and mining development across 12–35 m² cross-sections:
The KJ310 is engineered for hard rock tunnel cross-sections between 12 m² and 35 m², with automatic hydraulic self-leveling coverage of 6462 mm width × 5355 mm height and extended manual leveling coverage of 7250 mm width × 6120 mm height.
The KJ310 is a heavier 13,500 kg crawler/carrier class jumbo designed for larger 12–35 m² headings, equipped as standard with a 75 kW electric-hydraulic power unit, a 4 kW (5.8 m³/h) water pump, 20° climbing capability, ±10° rear axle oscillation, and the heavy-duty K 26F self-leveling boom.
