KJ215 full hydraulic tunneling jumbo is a heavy-duty single-arm equipment for large roadways and long tunnels above 2.4m. The high-power rock drill performs well on hard rock such as granite and basalt. The widened & thickened crawler improves grip and climbing ability for stable travel on complex terrain. The multi-angle hydraulic boom realizes full coverage, and the built-in anti-jamming system protects drilling tools. Explosion-proof, dust-proof and eco-friendly exhaust design ensure stable heavy-duty operation. It is the preferred equipment for hard rock tunneling of large mines, main coal roadways and long water tunnels overseas.
Suitable for roadways above 2.4m×2.4m. Compact layout and flexible turning, ideal for main roadways and long tunnels.
18kW rated impact power optimized for granite, basalt and dense limestone. Higher efficiency than conventional models for hard rock projects.
Low ground pressure and strong grip. Maximum climbing angle reaches 24°, running stably on steep slopes, gravel and mud.
±178° rotation and ±60° luffing enable drilling on face, side walls and roof. No frequent relocation to improve efficiency.
Special anti-jamming circuit releases pressure and reverses automatically. Overload, oil temperature and under-pressure protections enhance reliability.
International Ex explosion-proof certification, IP54 protection and exhaust purification meet overseas mine safety and environmental regulations.
Sensitive hydraulic response and smooth movement ensure high drilling accuracy and less rework.
Vibration and fatigue resistant structure optimized for long-term heavy load, ensuring project schedule.
Single-person hydraulic levers for easy operation. Modular components simplify on-site service and parts replacement overseas.
