E-ONE (Emergency One) fire tanker truck custom rescue vehicle

E-ONE (formerly Emergency One) is a leading global manufacturer of fire apparatus and emergency vehicles. Headquartered in Ocala, Florida, the company is a "single-source" manufacturer, meaning it engineers and builds the entire vehicle—including the chassis, cab, body, tank, and aerial device—in-house.

Key Products and Innovation
E-ONE produces a wide range of emergency vehicles tailored for municipal, industrial, and airport use:
Aerials & Ladders: Includes aerial platforms, tractor-drawn aerials (TDAs), and specialized ladders like the Metro series.
Pumpers & Tankers: Offers custom and commercial models, including the eMAX series designed for maximum storage and maneuverability.
Rescue Vehicles: Available in walk-in, non-walk-in, and light rescue configurations.
ARFF (Aircraft Rescue Firefighting): Specialized Titan vehicles for airport emergencies.
Electric Vehicles: Recently introduced the Vector, the first fully electric fire truck in North America.

Manufacturing & Operations
Locations: Main manufacturing occurs at the Ocala campus, with an additional facility in Hamburg, New York, that focuses on stainless steel pumpers and tankers.
Pioneer Status: Founded in 1974, E-ONE pioneered the use of extruded aluminum in fire truck bodies, which offers superior corrosion resistance and a lighter weight compared to traditional steel.
Ownership: E-ONE is currently a brand under Terex Corporation (formerly part of REV Group).
Recent Expansion: In March 2026, E-ONE announced a $23.5 million investment to expand its Ocala facility, aimed at increasing aerial production capacity by 35%.
