Liebherr R 9800

R 9800 G6 Hydraulic excavators are the machines that actually fill the giant trucks further down this list, and Liebherr's R 9800 is one of the very biggest in the class. The current G6 weighs 800 metric tons as a backhoe or 810 as a face shovel, with a 47.5-cubic-meter backhoe bucket and two engines rated together at 2,984 kW. For sheer weight, Caterpillar's 6090 FS goes further still. The R 9800 is the one you will find on Liebherr's current mining range.
