KJ310 Full Hydraulic Tunneling Jumbo

KJ310 full hydraulic double-arm tunneling jumbo is a medium mining equipment featured with high efficiency and flexible movement. It is designed for underground roadways, road & railway tunnels and water tunnels with section above 2.6m×2.6m. Equipped with two independent hydraulic booms, dual rock drills, explosion-proof crawler and central control system, it works synchronously or in separate areas with remarkable efficiency advantages.

Each boom realizes multi-angle adjustment. The 15.5kW hydraulic rock drill drills efficiently on soft and medium-hard rock, and each set is equipped with intelligent anti-jamming protection. The flexible crawler has stable climbing ability. The compact body adapts well to medium roadways. Compliant with mining Ex explosion-proof and IP54 dust & water proof standards, it runs with low noise and qualified exhaust. It supports 24-hour continuous operation in gas, dusty and humid underground areas. Easy to operate and maintain, it is core construction equipment for overseas medium mines, tunnels and underground support projects.

Dual-arm coordination, doubled working efficiency
Two independent booms and rock drills work synchronously or separately. The efficiency is increased by over 50% compared with single-arm models to shorten project duration.
Compact body, good adaptability for medium roadways
The rational layout has minimum turning radius ≤2.75m, moving freely in roadways above 2.6m with strong universality.
Full hydraulic system, smooth movement & high precision
Pure hydraulic drive for all movements. Smooth transition and high drilling accuracy improve hole quality and reduce rework.
Dual rock drills & independent anti-jamming
15.5kW single impact power adapts to various rock types. The independent anti-jamming system protects tools and reduces loss.
Off-road crawler, good trafficability
Thick steel crawler has firm grip. The maximum gradient of 22.5° ensures stable travel on steep and gravel roads.
Multiple mining safety protections
Official Ex explosion certification and IP54 full seal. Overload, oil pressure and water temperature protections ensure safety in high-risk underground areas.
Low noise & eco-friendly design
Optimized noise reduction and exhaust structure comply with overseas mine environmental and health standards.
Central control, single-person operation
Integrated levers with clear layout are easy to use, saving labor cost.
Modular layout, convenient maintenance
Hydraulic, power and travel parts are arranged in zones. Wearing parts are concentrated for easy on-site service overseas.
24-hour continuous operation, stable performance
The fully tuned system has strong load capacity for long full-load operation to guarantee project schedule.
