KJ212 Full Hydraulic Tunneling Jumbo

KJ212 full hydraulic tunneling jumbo is a well-balanced medium single-arm mining equipment, featured with large working range, flexible movement and durable performance. It is mainly applied to underground roadways, road tunnels and water tunnels with section above 2.2m×2.2m. The integrated design combines explosion-proof diesel engine, full hydraulic boom, high-power rock drill, crawler chassis and central control system for flexible relocation without extra accessories.

The full hydraulic system ensures smooth movement and precise positioning. The multi-angle boom covers large working area. The powerful rock drill adapts to various rock types. The built-in anti-jamming function protects drill rods and bits. Certified by mining explosion-proof standard and IP54 grade, the low-noise unit works safely in humid, dusty and gas-containing underground environments. Easy operation and low failure rate enable 24-hour continuous operation. It is core construction equipment for overseas medium mines, conventional tunnels and underground bolt support projects.

Large working range, good adaptability for medium roadways
The hydraulic boom has wide rotation and luffing angles. It completes large-area hole layout without frequent relocation, suitable for roadways above 2.2m with strong universality.
Full hydraulic drive, precise and smooth operation
Hydraulic system drives all movements with sensitive response and smooth transition. High drilling accuracy improves hole quality and reduces rework.
High-power rock drill, wide rock adaptability
16kW rated impact power delivers high efficiency on soft and medium-hard rock, meeting geological demands of mines and tunnels.
Intelligent anti-jamming, reduce operating cost
The hydraulic anti-jamming circuit releases pressure and reverses automatically when stuck, avoiding tool breakage and loss.
Off-road crawler, flexible relocation
Thick steel crawler has strong grip. The minimum turning radius is 2.7° and maximum climbing angle reaches 23°, suitable for steep slopes and gravel roads.
Multiple mining protections, high underground safety
Official mining explosion-proof certification and IP54 fully sealed structure. Oil pressure and overload protections ensure safe operation in high-risk underground areas.
Low noise design, eco-friendly working environment
Optimized noise reduction complies with overseas occupational health and environmental standards.
Central control, easy to operate
Integrated hydraulic levers with clear layout for single-person operation, no professional training required.
Modular structure, convenient maintenance
Hydraulic, power and travel parts are arranged in zones. Wearing parts are easy to replace for on-site service overseas.
24-hour continuous operation, stable performance
Optimized heat dissipation and load capacity support long full-load operation to guarantee project schedule.
