Warn Industries is a manufacturer of vehicle recovery equipment and off-road vehicle accessories. The company produces products for use on trucks, powersports vehicles, wreckers, military vehicles, and trailers. Warn Industries is based in Clackamas, Oregon, a suburb of Portland. The company was founded in 1948 by Arthur Warn, who invented a locking hub system designed for use on surplus World War II Jeep vehicles. Originally based in Seattle, Washington, Mr. Warn worked with Belleview Manufacturing of Portland, Oregon to manufacture the bolt-on/bolt-off hubs. By 1954, the hubs were available as optional equipment through several major automakers. In the late 1950s, Warn Industries pioneered the development of the electric winch for use on a recreational vehicle. Previous to the electric winch, most users of four-wheel drive vehicles utilized a winch driven by a power take-off (PTO) system of hydraulic system. However, PTO and hydraulic winches will not operate if the vehicle is not running. The application of the electric winch would allow for vehicle self recovery, even if the engine had stalled. The first unit sold was initially called the Model 6000 (M6000), although it became known as the Belleview. It had a capacity of 6,000 lbs. In 1974, the company would update its Belleview winch to the M8274, which featured more modern components and an 8,000 lb. capacity.
