On his Flickr photostream, rottemannen posted 6 pictures and a video of his Lego Technic Crawler Crane.  

In the short (main boom only) configuration (shown in the first picture below):
* Main boom: 112 studs
* ~3 kg ballast, 1.8 kg central ballast

In the tall (main boom + jib) configuration (shown in the second picture below):
* Main boom: 152 studs
* Jib: 140 studs
* Total: 292 studs / 2330 mm (2.3 meters = ~7.5 feet high)   *oh2*
* 0.4kg lift (should be able to lift 4x more, will test later)
* 3kg ballast + 1.8kg central ballast

The third picture below shows it lifting 7800 grams (7.8 kg = ~ 17 pounds!)   :thumbup:

Pretty sure I have enough parts to build that..

however I don't think 'Rainbow Coloured' cranes are very popular in the building industry!! ;)

that XL motor at the rear could do with some support!!

I really fancy building a crane.  Just not got around to it.  Impressed how much this can lift!
