Liebherr Mining has launched the R 9100 Generation 8 (G8), the latest addition to its range of 100-tonne class mining excavators. Following successful pre-series field validation in Indonesia, the R 9100 G8 is now available for purchase and will replace the R 9100 Generation 6 (G6) once series production begins in the second quarter.
To help customers keep fuel costs as low as possible, the R 9100 G8 comes with Liebherr Power Efficiency (LPE), Liebherr’s proprietary engine and hydraulic management system designed to reduce fuel consumption while maintaining productivity. Compared to the R 9100 G6, the new excavator consumes 20% less fuel and delivers 30% higher fuel efficiency, enabling fuel savings of up to 100,000 liters per year, according to the OEM.
The excavator benefits from several G8 upgrades, such as:
- A fully redesigned electro-hydraulic control system for smoother and more precise operation.
- An optimized attachment and hydraulic circuit to reduce pressure losses and improve cycle times.
- Integrated IMUs for cylinder dampening, enhancing component protection and reliability.
- A redesigned undercarriage with lifetime-sealed travel drives as standard.
- Grease change intervals are extended to a minimum of 250 operating hours, helping to reduce downtime.
Like all G8 excavators, the R 9100 is compatible with a range of products within the IoMine technology suite, such as Assistance Systems, Skyview 360° vision system, Bucket Filling Assistant, Data View and Data Services. These products, along with the rest of IoMine’s offerings, support mine operators’ transition to integrated, safer, more efficient and more sustainable operations.
Both the backhoe and face shovel configurations of the R 9100 G8 are available for purchase now. Backhoe configuration will enter series production in the second quarter of this year, with series production of face shovel configuration following shortly after in Q3.
Pre-series field validation of the Tier 4 / Stage V version is scheduled to begin in 2027.
