Liebherr’s big excavators always impress

One thing you can always count on from Liebherr at Bauma, is the presence of a big excavator on its stand usually sat next to an equally large dumptruck!

At the 2013 edition of the Bavarian machinery fest in Munich, Liebherr showcased its face shovel version of the R 9400 which tips the scales at 345-tonnes and competes in the 400-tonne class sector.

Last year Liebherr delivered a backhoe version of this giant mining excavator, one of 65 units working globally, to the Colorado based Trapper Mining Inc, who were previously using a large wheeled loader on this operation, although traditionally they have a long history of running large rope-controlled draglines at this operation.

The model deployed at Trapper Mining features the latest USA/EPA Tier 4 Final diesel engine which is rated at 1,250 kw (1,675 hp). The machine was also supplied with specially built 37-cubic-yard optimized bucket which enables the machine to load 240 tonne capacity trucks in 4 passes. Check out this video from Liebherr featuring the machine which has been given the nickname “The Duke” typically an American name relating to the famous Hollywood actor John Wayne.
