E-One Inc.

E-One, or Emergency One, is a fire apparatus manufacturer located in Ocala, Florida. One of the largest fire apparatus manufacturers in the world, E-One trucks can be found in many countries.

History
Formed in 1974 by retired playground equipment manufacturer Robert Wormser, Emergency One grew quickly and became the largest fire apparatus builder in the United States by the mid-1980s. The company pioneered the use of modular bodies built from extruded aluminum components, enabling it to build in advance and speed up production time considerably. It built a new 75,000 plant in Ocala to meet production needs in 1978. A new line of aerial devices was launched in 1981 - the company had built earlier aerial-equipped apparatus using ladder assemblies purchased from an outside supplier. The Hurricane custom chassis was introduced in 1984, leading to a full line of custom trucks.

Corporately, in 1979, Emergency One was acquired by the Federal Signal Corporation. The chassis business was spun off into a separate entity called Federal Motors in 1985, and Emergency One officially changed its name to E-One in 1988.

In the late 1980s, E-One began to acquire other apparatus manufacturers. In 1989, it purchased Florida-based American Eagle. In late 1991, E-One entered the Canadian market in force with its purchase of Superior Emergency Vehicles. In 1998, Saulsbury Fire and Rescue Corporation of Preble, NY was added to the E-One family. The three plants purchased were closed in 1992, 2006 and 2004, respectively.

E-One continues to build a full line of trucks from plants in Ocala and Hamburg, NY.
