Dual Internal Systems
A hook-and-ladder fire truck has two steering wheels. The one in the cab is much like that in any other vehicle. The driver sees a pothole in the street, turns the steering wheel to avoid it, and the front wheels respond. The second steering wheel is manned by another driver perched high atop the tail end of the long truck. With it, he steers the back wheels. Without such an arrangement, the truck could not maneuver around corners. Working in tandem, the two hook-and-ladder drivers operate an effective apparatus for fighting fires and saving lives. Out of balance, they provide a spectacle fit for a Mack Sennett comedy.
