Leibherr’s LTM 1090-4.1 mobile crane is an impressive piece of construction equipment with a top speed of 85km/h, a telescopic boom up to 50m, and a maximum load capacity of 90 tonnes. If that doesn’t impress you, then this scaled LEGO version of the mobile crane by Dirk Klijn should attract your attention. Dirk has spent 3 and a half years working on this 80cm long model that has 5 Sbrick‘s controlling 17 functions, including driving, working rear lights, indicators and reversing lights, boom and jib extension, power-lifting objects, steering and motion, as well as non-motorised functions such as full suspension, opening doors, and the manual folding jib.

On a model this big, there are plenty of details to pore over…

Dirk has ensured that his scaled model has a full complement of counterweights to allow maximum lifting power. With the jib fully extended, this model stands 2.6m tall (8.5 feet), which makes it an ideal piece of equipment for even the most demanding of LEGO construction sites.

I wonder if it emits a loud warning BEEP when it reverses?
