The giant amongst the caterpillar excavators on construction sites and for surface mining is a true colossus. Even in HO scale. The brand new R9800 series from Liebherr incorporates the largest and strongest excavators in the world. The model, which virtually only consists of metal, is transported safely to its next place of use between two crawler chains. The huge face shovel excavator arm is fully functional and loads the mining dumper in a jiffy. The driver's cabin and access ladders are precise in detail and complete this exceptional model.
