This is another one of those videos that just defy all odds. Not sure why anyone would want to do this, or if it's even practical, but man it's cool as heck. 

It seems as though the Germans have taken motor sports to a whole new level, literally. Check out this video from 2014 that shows an excavator lifting itself to the top. Of course it has locking supports on both the tracks and on the business end of the machine, but still, wow and holy cow.

I'm guessing this was a demonstration of the strength and durability of the excavator but in all actuality, a tower like this could be built on any job site to get an excavator to the top of the job I suppose and it could be as tall as they wanted if they could support the weight.

I think the craziest thing about it is the announcer stands right under the thing the whole time.
