Product Description
Features
This dual-boom mining hydraulic jumbo is engineered for efficient drifting and production drilling in medium-to-large underground mines, adapting to drift cross-sections from 4.5×4.5 m to 8×6.8 m. It features two independent, fully hydraulic drilling systems that operate simultaneously without interference, dramatically boosting construction efficiency.
Equipped with high-power rock drifters, it delivers a penetration rate of 0.8-2.5 m/min even in F17 hard rock, while the dual-damping design extends tool lifespan and reduces maintenance costs. The fully hydraulic parallel telescopic boom offers 360° coverage, enabling full-face drilling in a single positioning. Paired with an articulated chassis and four-wheel drive, it provides 14° climbing capability and a travel speed of 16 km/h, ensuring excellent mobility in narrow drifts.
To ensure safety and stability in harsh underground conditions, it integrates automatic anti-jamming, rod retraction, and collision protection functions, alongside a full wet braking system. A FOPS (Falling Object Protective Structure) and ROPS (Roll Over Protective Structure) certified canopy also provides robust protection for operators.
Key Features & Benefits
- Dual-System Simultaneous Operation
Two independent hydraulic drilling systems work in parallel to eliminate downtime, significantly improving efficiency in multi-task scenarios.
- Efficient & Precise Drilling
The fully hydraulic parallel telescopic boom with dual-triangle stabilization enables full-face drilling in one positioning, delivering fast penetration and exceptional stability.
- High-Mobility Chassis
Diesel-powered four-wheel drive articulated chassis with agile steering and strong climbing ability for rapid movement in complex drifts.
- Intelligent Protection Design
Automatic anti-jamming, rod retraction, and collision protection minimize downtime and extend component lifespan.
- Certified Safety Assurance
FOPS & ROPS certified canopy and full wet braking system provide dual safety guarantees for underground operations.
