Does anyone happen to know where I might be able to find more information and possible some engineering/schematic views of a large bucket-wheel excavator shown in the link below.  This is one of the largest machines on the planet and I think it would make for a great Solidworks project in large assemblies and really put certain cad technologies to the test.
