Quarry Duty JK830RC Crawler Mounted Reverse Circulation Drill Rig 25000kg 400mm Tracks 170kN Traction

This quarry duty JK830RC crawler mounted reverse circulation drilling rig is specified for the punishing, continuous drilling schedules of commercial aggregate operations. Weighing 25000 kg and riding on 400 mm wide tracks with a 2749 mm total width, the machine offers the stability and flotation that quarry floors demand, especially after blasting when the working surface is uneven and littered with spoil. The Cummins QSZ13 engine keeps the hydraulic system and RC flushing circuit at full performance throughout long shifts, while the 170 kN tractive force lets the operator reposition the rig quickly between holes without waiting for a dozer or loader to prepare the pad.

• Quarry-Rated Undercarriage: 400mm tracks and 2749mm total width provide a stable footprint on blasted bench floors.
• 25000kg Base Mass: heavy construction dampens vibration and improves hole straightness in fractured rock.
• 170kN Traction: rapid repositioning between holes reduces non-drilling time in production cycles.
• 335kW Cummins Power: sustained hydraulic output for long shifts in hot quarry environments.
• +/-10 Degree Track Oscillation: tracks conform to uneven ground, keeping the mast aligned.
• RC Flushing Efficiency: fast cuttings removal keeps the bit cutting fresh rock at depth.

This configuration of the JK830RC targets limestone, granite, basalt, and sand-and-gravel quarries that drill RC holes for grade control, aggregate quality testing, and deep production blasting patterns. The stable platform and powerful flushing circuit also make the rig effective for dewatering well drilling inside quarry boundaries, where operators need clean holes through overburden and weathered rock. Contractors running the machine on multi-site programs benefit from its self-tramming mobility, which eliminates the cost of low-bed transport between nearby pits. The 400 mm ground clearance protects the undercarriage when crossing blasted muck piles and wet sump areas.

Quarry-duty preparation includes reinforced track guards, extra undercarriage protection, and a full service before shipment. The rig is loaded by 40ft flat rack or RORO vessel with the mast lowered and secured. The documentation pack contains CE certification, engine compliance papers, operation manuals, hydraulic schematics, and a lubrication chart. Our service engineers support commissioning and can supply wear parts for the track system and RC drill string components from stock.
