LEGO CUUSOO

This model is a 19-axle superheavy transport rig. If you've ever seen one of these rigs roll down the highway, you'll probably never forget it. This set in particular (including the color scheme) is based on a configuration that is operated by the Hallamore Corporation (based in Holbrook, Massachusetts, not too far from where I live). Transports of this type are typically used to move heavy equipment for the power and mining industries, such as transformers, wind nacelles, hydro-electric turbines, nuclear containment vessels, and parts of large excavating equipment (such as bucket-wheel excavators). The idea behind these transports is to spread the weight of a heavy load so that the per-axle load meets the permit requirements for highway travel (i.e. so that the transport doesn't tear up the road).

There have been a few offical LEGO sets with heavy haulers, including the 7747 Wind Turbine Transport and the 7900 Heavy Loader, but I don't think there is anything quite like this model. It is built at minifig scale and it is almost 200 studs long -- that's about 1.6 meters! This model would pretty much grind those existing sets under its wheels :-). I have put a length comparison graphic in the main graphic to make it easier to visualize the difference.

Below is picture of a real 19-axle transport in action (not Hallamore's unfortunately -- I couldn't find a good picture of theirs).
