The World's Biggest Machine

This is the 45,000 ton Bagger 288 digger built by Krupps in Germany, and it is the largest land based machine built by humans on the face of the planet.
It’s not fast, moving at about 2 meters a minute, but boy can it shift rubble.
It can dig up 240,000 cubic meters of dirt a day. That’s about the same as a football field sized hole that’s 30 metres deep.
And why do you need a machine so absurdly big? So we can strip mine coal out of the ground, transport it hundreds of miles on massive trains and take it to power stations where we burn it to make electricity. And where does quite a chunk of this electricity go? Strangely back to the digger, as it requires 16.56 megawatts of electricity to operate. You’re not going to find a lot of solar panels on this leviathan.
Once it starts digging, it literally will not stop. Anything in its path will be chewed up, including this 60 ton bulldozer. How, I ask you, do you miss a 60 ton bulldozer?
