I read about this machine several months back on Wikipedia (I remember it is the only machine larger than NASA's crawler-transporters). The interesting thing is it doesn't look like it should even be able to balance itself (the trailer-thingy connected to it may act as a counter weight). Even so, it looks like it will still tip over sideways.
Now if they made it manless or even autonomous, it would be the ultimate strip-minner (manless mining, tell it were to dig and it will extract all the resources for you).
