The Making of a Fire Engine

The manufacture of a fire engine remains a custom, almost one-of-a-kind operation. Typically, a group of workers is assigned to the fabrication of the body and assembly of the truck frame. A separate group performs body finishing, then the apparatus is wired, equipped, and tested by a third, or "equipment," group. Aside from the body, manufacture of the fire apparatus is typically an assembly process. The process is described at How Products are Made.
