MiningTruck
Remotely controlled mining truck, after the Liebherr T 282 B, made from mostly the two LEGO sets 4958 "dinosaur" and 8297 "off-roader".
About this creation
This is a remote controlled mining truck, based on the huge Liebherr T 282 B. The model was made by techno moves and me from mostly the two LEGO sets 4958 and 8297, which are the dino and the offroader. In addition the plates and blocks for the bucket are from various sources, the green main plate being from a 30 year old (!) blue policestation, which might have been my first set.


The very big wheels in the off-roader set made us think what to build. We wanted to go for minifig scale, as a tribute to the thing being around 30 years now. But then the off-roader wheels are 4 meters high! Where do they use tyres that big?
The answer is simple: they use them in mining equipment...
The Liebherr T 282 B is the biggest commercial mining truck we know of. We downloaded the specification from Liebherr and studied it. Then we printed the side- front- and rear-views enlarged such that the printout was 1:1 for the model, the scale being determined by the offroader wheels, and about 1:50.

Here you see a photo from both the MOC (left) and a brochure (right) of Liebherr rendered on a laptop screen. I hope you recognize some resemblance?

Of course there are major structural differences between our MOC and the real thing. For one thing, the real one has independent electrically driven backwheels instead of our differential. The MOC is fed by the battery box (aka grill), and the real one has a 20 cylinder 90 liter diesel engine. Yes, the 90 liter is cylinder volume, not the fuel tank, which can hold 5000 liters!



We tried to mimick the real thing as far as we could, and chose the original grey/white color scheme, and including details like the stairs, railing, foldable ladder to get on, power converter box, airco, fire extinguishers etcetera.




Taking the scale into account our MOC performs more or less like the real thing: the MOC weighs very close to two kilograms, and can bear another two kilograms load relatively easy, and lift and dump it too! It can still drive around with three kilograms load, but dumping that fails, depending on the distribution of the load. This matches with the say 250 tons weight of the real one and a payload 350 to 400 ton. Moreover, the scale we build it is 1:50 for length, so 1:2500 for surface, so 1:125000 for cubical measures, like weights should be. Hence the model weighing 2 kilograms corresponds precisely to 250 tons in reality!


We were inspired and encouraged by the brilliant work by Beat Felber on http://www.engineeringwithabs.ch/. Clearly his model is a MUCH more precise copy of the real thing, our challenge was just to do it with these two technic sets (apart from the bucket) and to get it wirelessly remote controlled.

How much stress does 2 kilograms put on the frame? It seems like it would snap under the weight.

very nice i have a thing for heavy machines. altho you may want to reinforce your dump box if you lan tto keep and use your model.
