Perkins Specialized Transportation Contracting used model-based design and digital prototyping to design and build a 400-foot-long truck specifically to transport huge nuclear generators. The truck, which took nearly three years to build, provides a way to transport enormous, frequently radioactive components of nuclear power stations that were previously considered too large to move without disassembly.
The transporter recently successfully carried four 400 ton steam generators from Southern California Edison's San Onofre Nuclear Generating Station in to a disposal site in Clive, Utah, an 830-mile, roughly 21-day trip..
The truck is longer than a football field, has 192 wheels and 48 axles, each of which turns independently, enabling the truck to navigate sharp turns and different road grades. You can see videos here and here and at the Perkins site.
