This is the largest digging machine (or trencher or rotating shovel) in the world. It was built by Krupp and is shown in one of the pictures, crossing a road in Germany on the way to its destination, an open air coal mine. Although at the mine the treads are unnecessary, it was cheaper to make the machine self-propelled than to try and move it with conventional hauling equipment. Some factoids:

* The machine is 104 yards high and 235 yards long (almost 2.5 football fields in length)
* Weight is 45,500 tons (that's equivalent to a bumper to bumper line of jeeps 80 miles long)
* It took 5 years to design and manufacture at a cost of $100 million
* Maximum digging speed is 10 meters per minute
* Can move more than 76,000 cubic meters of coal, rock, and earth per day

From Here on you will find statements from a post online

IT’S A MACHINE TO HARVEST “BROWN COAL”. I don’t know if “brown coal” is the right word in english, it’s the coal which is closest to the surface. we have some of those machines in germany
well, as you can clearly see on the signs attached to the machine, it is designed and constructed by “Krupp” - which was (and is) also the producer of german heavy artillery and tanks since world war I and II. so “giant killing machine” is not quite false but in fact is is a giant dozer/digger for brown coal open mining.
Nothing too special. These giants are widely used in the Ruhr area und Lusatia in Germany and most probably in the mining industry elsewhere
The picture in question is not Photoshopped — in other words, a picture of a small earth mover has not been … (edited)
Saw this on a special on the Discovery Channel “Mega Machines” or something. No it’s not photoshopped, and it digs mines. The entire upper section rotates 360 degrees to dig a circular pit. And yes, it’s huge. I believe they had two of them that needed to travel a ridiculous distance from one site to another, and they needed to build special “roads” for them to travel on, since they weigh like a million tons. Very cool stuff. Wouldn't want to get run over by it, kinda like getting hit by a glacier.
What you see in that picture is ‘Bagger 288′ (the world’s biggest bucket-wheel excavator) crossing the Federal highway 55, en route to Garzweiler in Germany.
The picture was taken February/March 2001. Bagger 288 was build by Krupp and is owned by RWE Germany (it’s part of a fleet of 21). They use it for open cask lignite mining. The German word ‘Bagger’ means excavator or digger, btw. It’s about 96 meters high and 240 meters long, has a weight of 13500 tons, it’s top speed is 10 meters a minute, and it is operated by just 5 people.
As you can see from the photos, that isn’t a saw blade, but a bunch of buckets that pick up dirt and place it on a conveyer belt. Why the one in the picture above is just sitting in the middle of nowhere is beyond me.
