Why Is There a Tiny Cab at the Back of Some Fire Trucks?
You heard sirens the other day and dutifully pulled over to allow a long fire truck to pass you. But as it went around a tight corner you noticed something odd: A tiny cab at the very back of the truck holding just one fireman. No, he’s not up there for the view. He’s actually steering the rear axle.
A “tiller truck” is a ladder truck so long that it needs someone to steer the rear axle. And this “tiller man” job is an especially demanding one for a couple reasons.
First of all, why does the truck need more wheels that steer? So it can complete tighter corners–both going forward and backward. While racing to the fire, the main driving can take a tight corner through an intersection. Normally, this would run the middle of the trailer up over the curb, hurting bystanders. But with a tiller truck, the tiller man can steer in the opposite direction, cutting wide around the same corner.
You read that right. When the cab of the truck turns left, the tiller man cranks his wheel to the right. It’s a difficult, counter-intuitive job. That’s one reason the tiller man is up so high, so he can see the surroundings and navigate tight intersections packed with traffic. But the problem with the little one-man cab he sits in is that it almost never has no creature comforts such as A/C. So it’s not a very comfortable place to hang out in full firefighting gear.
So what about when the ladder truck needs to back up some narrow alley to reach a building on fire. In this case, the tiller man must turn around and navigate the trailer to avoid obstacles. And of course, he still must steer the wheels in the opposite direction from where he needs to go.
Finally, when the fire department reaches the disaster scene, it is usually the tiller man who is the first firefighter up the long ladder. Talk about a tough gig!
That said, tiller trucks can be invaluable tools for certain departments. Vernon, California Fire Department captain, Todd Schoenig told Motor Trend, “The beauty of this truck is you can really maneuver it well…It goes through traffic easily, we can back it down small alleys to ladder, and we can do a lot of things that you wouldn’t be able to do unless you had that tiller in the back.”
