Here is another video on Bucket Wheel Excavators (BWE), though smaller than Bagger 293. This one is a 45 minute episode of Dirty Great Machines. It covers some BWEs in Greece, a company in Germany that builds the gear boxes, for these things. It also covers some smaller machines mining iron ore in Australia. I find this kind of thing fascinating. (I also love the fact that some of the BWEs were built by Krupps. If you know Krupps it is because they make coffee equipment for restaurants.)
The quote that forms the title to this post comes from the video.
