Slower than a speeding bullet, more powerful than a locomotive

I was recently at the Caterpillar Visitors Center in Peoria, looking at the big construction vehicles made for shaping the Earth in a profound way, from the gigantic mining dump trucks to the tiny little excavators. Somewhere in between are the bulldozers, offered in nearly a dozen sizes. The biggest Caterpillar, the D11, is one huge rig, but shockingly it isn’t the biggest dozer around. That title belongs to the Komatsu D575A-3 Super Dozer, weighing in at 336,400 pounds and measuring 38+ feet long, 24+ feet wide at the blade, and 16 feet high. While Beat Felber‘s LEGO model is not quite so large, it is not small, either. The builder has a whole series of 1:28.5 scale machines, from dump trucks to mining shovels, and the Super Dozer is a super addition to the lineup. The little kid inside of me is drooling all over the keyboard as I look at this beast, because this is the bulldozer every kid imagines driving as a construction worker.

This epic LEGO coal mining shovel is nearly as tall as its builder

If this 1:28.5 scale model of the Marion 5760 Mountaineer stripping shovel doesn’t make your jaw hit the floor, then I suggest you take a closer look. Personally, I am glad that it is equipped with robust power functions to lift mine back up. Beat Felber, also known as Engineering with ABS, has created an absolutely stunning model of this monster of a machine used to scrape off the top layers of earth from seams of coal in Ohio. The Mountaineer was in operation from 1956 until 1979, and considering how massive the LEGO model of it is, I can only imagine how enormous the real thing was. It must have moved a lot of dirt. I almost said “a ton of dirt”, but I’d bet the shovel could lift a lot more than a ton of rock and dirt in every scoop. (It was closer to 60 tons per scoop! – Ed.)
