The R 9800 Mining Excavator By Liebherr

This is the R 9800 Mining Excavator by Liebherr, announced the last month at the MINExpo 2008 in Las Vegas. If you haven’t noticed, it’s big. 800 tons worth of service weight big.

According to Liebherr, the R 9800 provides a nominal bucket capacity of 38 to 42 m³ at a material density of 1,8 t/m³. 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 1,492 kW / 2,000 hp each or two MTU 12V4000 with a installed power of 1,425 kW / 1,910 hp.

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 1,840 kN with a digging force of 1,750 kN. In shovel configuration, the machine is achieving crowd forces at ground level of 2,980 kN and breakout forces of 2,350 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.
