At the MINExpo 2008 in Las Vegas, Liebherr announced the R 9800 Mining Excavator. Rated at 800 tons of service weight the R 9800 provides a nominal bucket capacity of 38 to 42 m? at a material density of 1,8 t/m?. This new flagship of Liebherr mining excavators' range is targeting bucket loads of 75 tons in both versions, as a backhoe and a shovel execution. Liebherr is providing for the machine two engine options, two Cummins QSK 60 with a installed power of 2000 hp each or two MTU 12V4000 with a installed power of 1910 hp each. Whilst the backhoe digging envelope and bucket width remain similar to the previous Liebherr flagship, the R 996, the R 9800 in backhoe configuration provides a break out force of 1840 kN with a digging force of 1750 kN. In shovel configuration, the machine is achieving crowd forces at ground level of 2980 kN and breakout forces of 2350 kN. These values ensure superior digging capabilities even in toughest mining conditions. The first units of the new flagship are currently in the final stages of factory testing and the first machine is soon due for operation in Australia.
