You’ve all probably seen trailers towing massive pieces of construction equipment before or machinery that demands an escort with “Oversize Load” signs draped all over them. However, most of you have likely never seen a trailer so massive that it actually required its own rear driver sitting in a cab by the back. Well, if you’ve never seen such a thing before and were wondering what it looked like, today’s your lucky day. Get pumped!
This unique dual-driver truck/trailer combination is used to transport aircraft wing spars to the Boeing assembly facility in Everett, Washington. As you can see from the above video, there is one driver steering in a cab underneath the trailer, just in front of the rear wheels, while there is another driver in the front, like any other truck.
The steer car is attached to the back of a long truck that hauls large structural components for wings about 70 miles (113 kilometers) from Boeing’s Fabrication facility in Frederickson, Washington to its factory in Everett.
That’s a pretty wild combination, isn’t it? If you’ve always wondered how they transported massive airplane parts from one place to another, now you know. It’s definitely not something you see every day, that’s for sure. And also not something you’d want to be stuck behind if you had some place to go in a hurry. But pretty cool to see in action nonetheless.
As one commenter points out, this whole trailer combination vehicle setup is kind of reminiscent of that scene in Christmas Vacation where Clark Griswold gets the family car stuck under the truck. You know, minus the impending danger.
