Hydraulic System: Proportional pilot control, system working pressure 90–125 Bar

Applicable Drifts: Pre-support hazard clearing construction for regular underground excavations of small-medium metal mines and water diversion tunnels

Compact 1.75m narrow frame custom-built for regular drifts of small-medium mines and water tunnels, barrier-free transit in confined cross-sections
8.3m foldable full-coverage boom with 8.8m unilateral working width realizes dead-zone-free removal of unstable rock on tunnel roof, side walls and floor
SOOSAN SB30 hydraulic breaker outputs steady 350J impact energy to efficiently crush loose rock and drastically cut manual auxiliary workload
±120° swing breaker matched with mechanical parallel moving structure enables multi-angle posture adjustment for irregular tunnels with height difference
Diesel power matched with proportional pilot hydraulic control delivers smooth shock-free movement, single operator independently finishes full-section hazard removal of entire drift
Articulated 4WD chassis with wet multi-disc brake, max 14° gradeability, small inner & outer turning radius for flexible U-turn and transit in narrow mine drifts and tunnels
Officially FOPS & ROPS certified falling-rock safety canopy isolates roof collapse injury hazards, optional wireless remote enables long-distance safe construction
60kW Cummins explosion-proof diesel engine with exhaust catalytic purifier fully compliant for all underground mining drifts with gas and heavy rock dust
Solid heavy-duty 12-ton machine frame supports 24/7 long continuous scaling operation with low failure rate and extended service life
Multi-purpose single machine covers four core underground procedures: roof scaling, side wall trimming, floor leveling and working face hazard elimination
Full modular split layout allows separate disassembly, maintenance and replacement of boom, hydraulic breaker and travel chassis to lower overseas service cost
Universal standardized breaker spare parts easy to purchase for global mines with stable after-sales parts supply
