Bagger 288: World's Largest Digging Machine

This is the largest digging machine (or trencher or rotating shovel) in the world. It was built by Krupp and is shown here 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.

The World's Largest Digging Machine is almost 95 meters high and 215 meters long which is just like almost 2.5 football fields in length with 45,500 tons in Weight. Maximum digging speed is 10 meters per minute and it can move more than 76,000 cubic meters of coal, rock, and earth per day.

"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"

That's not right.
If that was true it would only be possible to make one round trench and that's it.
Instead they keep on moving in a long line, eating away a bit of the coal, then turn around and digg the next few meters. The back part of the machine (seen best on pic 4) is moving "independently" from the main machine and drives next to a belt conveyor, unloading the coal.

Look for "Tagebau Hambach" on google maps to find the biggest open mine in Germany. The whole operation is divided into three simple steps:
Get to a depth of a few hundred meters, get the coal and close the hole.

The eastern part is where they are digging into the ground to reach depth. you can easyly spot some Schaufelradbagger and the stair structure of the digging. In the middle is a darker line, the actual coal, on the west is the place where they keep unloading the earth they digg away in the east.

Bagger 288, the one seen in the pics is in a mine a bit north of Hambach, called "Garzweiler" if you check it on google maps it's quite interesting as different zoom levels of the sattelite images is from different times revealing how much the face of the earth has changed in a few years.
