Now That's A Digger!

This bucket-wheel excavator, used in coal mining, is having a bit of a trundle through the German countryside.
It's 22km journey to it's new coalface took nearly six weeks, at 10 metres a minute, and at a cost of 7.5 million Euro's. (cheaper apparently than disassembly/reassembly)
The worlds largest, Bagger 288, weighs over 12800 tons, is 96 metres high, and uses enough electricity to power 15,000 homes.
