Built in 1973, massive to world record proportions, and able to service an entire mine at once, your Mom and the Terex 33-19 Titan have a lot in common.

Just one Terex Titan was constructed and – until 1998 – it was the largest mining truck in the world, at a staggering 350 tons. This incredible recreation of the mighty mining machine comes from Beat Felber of Flickr, who has rebuilt the Terex superbly in a huge 1:28.5 scale.

Beat’s model is so large in fact that LEGO don’t make tyres big enough, hence the non-LEGO 120mm tyres fitted – the only non-LEGO pieces used. There’s something authentic about this too, as the real Terex required six axles rather than the usual four as there were no tyres large enough available for a four-axle truck to take the Titan’s immense weight.

Beat’s astonishing replica of the 33-19 Titan not only looks spectacular, it functions too, with two very brave XL Motors driving the tandem rear axle and pair of Servo Motors powering the all-wheel steering. A further L Motor drives the two XL linear actuators that allow the enormous bucket to tip and two sets of LEDs illuminate the Terex’s head and tail lights, with all of that controlled by a third party SBrick programmable bluetooth battery.

Top quality custom decals and excellent presentation make Beat’s build a must-see, and you can do just that at his Terex 33-19 Mining Truck album on Flickr. Click the link and join us there, where it’s making our own Lego creations feel very small indeed.
