The R1250-9 excels in ultra-high-volume production mining where sustained material movement exceeds 800 tonnes per hour. The 7,550 mm boom with 3,400 mm arm configuration delivers 13,760 mm maximum digging reach with 581.5 kN (59,300 kgf) ISO bucket digging force, enabling efficient extraction from deep bench faces and loading of ultra-class haul trucks exceeding 150-tonne capacity without repositioning.
Bucket capacity ranges from 6.00 to 7.00 m³, optimized for loading 100-tonne and larger haul trucks with efficient pass counts. The machine completes loading cycles in 25-30 seconds under typical conditions, achieving hourly production rates exceeding 1,000 tonnes when matched with appropriate haul truck fleets.
The hydraulic system operates at 320 kgf/cm² relief pressure to implement circuits with power boost capability reaching 350 kgf/cm² for boom, arm, and bucket functions. This configuration delivers 511.9 kN (52,200 kgf) SAE bucket digging force and 423.7 kN (43,200 kgf) SAE arm crowd force with standard configuration, handling the most demanding materials without compromising productivity.
Consider the R1250-9 if your operation requires sustained ultra-high-volume production in demanding conditions, operates ultra-class haul truck fleets exceeding 100-tonne capacity, or demands maximum digging forces for handling extremely dense materials. Operations with lower production requirements or smaller haul truck fleets may find adequate capability in smaller capacity excavators.
Excavators in the 120-tonne class represent the ultimate in mobile excavation capability, purpose-built for the most demanding large-scale mining operations where material movement volumes directly determine operational success. The Hyundai R1250-9 delivers 552 kW (740 HP) of net power through its Cummins QSK23 engine, providing sustained ultra-heavy-duty performance in the extreme conditions encountered across Southern African mining operations. We supply the R1250-9 to major mining operations throughout the region with comprehensive technical support and genuine parts availability from our established network.
This 118,000 kg excavator operates at the scale demanded by ultra-class mining operations where hourly production targets consistently exceed 800 tonnes and equipment reliability determines mine profitability. The machine’s exceptional digging forces, extended reach capabilities, and robust construction address the specific requirements of large-scale open-pit mining operations throughout Southern Africa.
The Cummins QSK23 engine features a 23-liter displacement with electronic control optimizing combustion efficiency across all operating conditions. Fuel tank capacity of 1,475 liters supports extended operating shifts in remote locations. The machine consumes approximately 60-75 liters per hour under typical loading conditions, varying with material characteristics and operator technique.
The X-leg type center frame with integrally welded reinforced box-section track frames distributes operating weight across 52 track links per side. Standard 700 mm double grouser shoes provide 1.09 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.
