The R850LC-9 excels in high-volume production mining where sustained material movement exceeds 500 tonnes per hour. Multiple boom and arm configurations accommodate diverse application requirements. The 8.05 m boom with 3.4 m arm delivers 13,420 mm maximum digging reach with 443.3 kN (45,200 kgf) SAE bucket digging force, enabling efficient extraction from deep quarry benches and loading of ultra-class haul trucks without repositioning.
The extended 11.3 m boom with 8.0 m arm configuration achieves 20,540 mm maximum digging reach for specialized applications requiring exceptional horizontal coverage, such as canal excavation or stockpile management. Bucket capacity ranges from 1.65 to 5.20 m³, accommodating both precision work in confined areas and maximum productivity loading cycles.
The hydraulic system operates at 330 kgf/cm² relief pressure for implementing circuits with power boost capability reaching 360 kgf/cm² for boom, arm, and bucket functions. This configuration delivers 388.3 kN (39,600 kgf) ISO bucket digging force and 248.0 kN (25,290 kgf) ISO arm crowd force with standard boom/arm setup, handling abrasive materials and dense rock formations without compromising cycle times.
Consider the R850LC-9 if your operation requires sustained ultra-high-volume production in demanding conditions, handles material densities consistently exceeding 2,100 kg/m³, or demands extended reach capabilities for specialized large-scale excavation applications. Operations with lower production requirements may find adequate capability in smaller capacity excavators.
Excavators in the 80-tonne class represent the pinnacle of mobile excavation technology, designed specifically for high-volume mining, major quarrying operations, and large-scale civil infrastructure projects. The Hyundai R850LC-9 delivers 366 kW (490 HP) of net power through its Cummins QSX15 engine, providing sustained heavy-duty performance in the most demanding Southern African mining environments. We supply the R850LC-9 to major operations across the region with comprehensive technical support and genuine parts availability from our established network.
This 84,000 kg excavator operates at the scale required by large-scale open-cast mining operations where hourly production targets exceed 500 tonnes and equipment reliability directly determines operational profitability. The machine’s exceptional digging forces and extended reach capabilities address the specific requirements of deep-bench mining and large-scale material handling throughout Southern Africa.
The Cummins QSX15 engine features electronic control optimizing fuel-to-air ratios for efficient combustion while meeting Tier 3 emission standards. Fuel tank capacity of 940 liters supports extended operating shifts in remote locations. The machine consumes approximately 40-50 liters per hour under typical loading conditions.
The X-leg type center frame with integrally welded reinforced box-section track frames distributes operating weight across 51 track links per side. Standard 700 mm double grouser shoes provide 1.10 kgf/cm² ground pressure, with options for 800 mm and 900 mm widths reducing ground pressure to 0.87 kgf/cm² for challenging underfoot conditions.
