Hello; That excavator dolly was pretty cool. I didn't know those existed. Seems like a very fast method of moving these things around short distances. At 2:20 gives you some perspective seeing the men in the shot, as to how immense these machines are! Love to build a lake big enough to employ some of this huge iron! Why do operators stop when loading onto a dove tail, they should always move to a position where they won't bust the beads on the tires of the trailers first. When I see something strange happening to a piece of heavy equipment I listen to the language and "oh yeah, that's in Russia". They do things different over there. Most of these are only dangerous to the machines. Seriously who the hell drives their dozer out into a frozen river? Kind of disappointing the clips I wanted to see were too short and the rest is people trying to ice skate with dozers.
