That's A Big Crane

Whenever one of these behemoths passes me on the road I'm in awe. Humans sure can built some crazy big stuff can't we? But I think seeing this colossal MOC by Dirk Klijn in person would be equally awe inspiring. This is the culmination of over three and a half years of work, and it shows. With five S-Bricks controlling over 17 functions it's a workhorse as well. I can't wait to see video of this baby in action. Click through for loads more pictures including a lot of WIP.

Tadano Mobile Crane

Way back when I built a lot of Technic. Not really my own MOCs, but I did buy a lot of sets, especially the big ones. So I have a somewhat vague idea what went into the engineering behind this behemoth by builder Engineering with ABS. But I'll emphasize vague, because even the largest LEGO produced set pales in comparison to this mechanical marvel. Just check out the specs in the bottom picture, it's really impressive.
