That’s how long it took builder Dirk Klijn to design, engineer and construct this utterly spellbinding Sarens-liveried Liebherr LTM 1090 4.1 crane, in full road configuration with boom extension and 14 tons of counterweight.

Seventeen working motorised functions are controlled by no less than five third-party SBrick devices, making the Liebherr one of the most advanced Lego models that this site had ever featured, and if that wasn’t enough the model also features all-wheel suspension, a manually folding boom jib and two highly detailed accessible cabins.

Dirk’s model is also one of the most visually realistic creations we’ve ever found too, with a wealth of superb detailing further enhanced by custom decals produced by previous bloggee JaapTechnic, and full LED lighting.

A suitably large gallery of stunning imagery is available to view now at Dirk’s Flickr photostream – click this link to jump to Liebherr LTM 1090 4.1’s full album – we’ll see you there.
