LEGO’s huge 42082 Rough Terrain Crane is one the largest Technic sets the company has ever created, with over four thousand pieces. That’s a whole, lot of bricks that can be, in the very best traditions of Lego-building, repurposed.
And that is exactly was previous Master MOCer Nico71 has done with this incredible 4×4 Crane Truck, constructed only from the parts found within the 42082 set. Nico’s B-Model (in fact for Nico this is an ‘E-Model’, as he’s constructed several alternate vehicles (and all of this) from the Rough Terrain Crane set already) deploys the set’s single motor to perform a scarcely believable six separate functions, thanks to a pair of gearboxes that multiply the motor’s outputs.
Before we get onto those though, there are a host of mechanical functions too, including leaf-spring suspension, a V8 engine driven by all four wheels, opening doors, functioning steering, and the boom’s final extension.
The single motor delivers just as much on its own, thanks to those two gearboxes, powering the crane’s two-fold unfurling and rotation, the outriggers, and the truck’s tipper, which can tip both to rear and side of the vehicle depending upon which gear is selected.
It’s a brilliant feat of engineering and one that you can explore for yourself if you own a Technic 42082 Rough Terrain Crane set, as Nico has made instructions for this unbelievable B-Model available via his excellent website.
