Custom-built for standard medium underground stopes 3.5–5m, universal long-hole construction rig for non-ferrous, phosphate and limestone underground mines
360° full rotatable heavy feed beam + translational rail enables parallel hole layout within 3m to cover full working face per single positioning without frequent machine relocation
Integrated full auto storage & changer system for 27 drill rods with max 42m economical long-hole depth eliminates multi-person rod handling and drastically cuts downtime
Dual limit structure of front-rear hydraulic jacks + dedicated rod guide cylinder on feed beam delivers excellent long-hole straightness to reduce hole deviation and blast overbreak waste
24kW high-power stepped piston high-frequency drifter optimizes impact transfer efficiency for faster hard rock long-hole penetration and lower drill rod & bit consumption
Dual-purpose single machine for blast long hole & cable bolt support drilling covers two core underground mining long-hole procedures to cut mine equipment procurement cost
Closed hydraulic articulated 16-ton heavy 4WD chassis with max 14° gradient and small turning radius for flexible U-turn & short-distance relocation in narrow stopes
Officially FOPS & ROPS certified falling-rock safety canopy matched with wide-vision trolley console, optional wireless remote control to avoid roof collapse hazards
Mining explosion-proof diesel power with exhaust catalytic purifier, fully compliant for all underground mining roadways with gas and heavy rock dust
Built-in synchronous high-pressure air-water slag removal & dust suppression mechanism eliminates hole slag accumulation and reduces dust during full long-hole drilling cycle to extend internal drifter seal service life
Full modular split machine layout allows separate disassembly, maintenance and replacement of drilling unit, travel chassis and hydraulic pipeline components to lower overseas service cost
Standard equipped independent air compressor & electronic pulse automatic shank lubrication guarantees stable non-stop long-hole operation for long shifts and higher machine availability rate
