As wheel loaders increased in size, safety concerns arose, particularly concerning the positioning of the loader pivot arm. These concerns ledto the adoption of a front mounted pivot in the late 1950s. Hough was one of the first manufacturers to produce a wheel loader with a safer design, followed quickly by Caterpillar, Case and Allis-Chalmers.
Today's wheel loaders are comprised of a pivoted frame with the engine mounted over the rear wheels. A cab or canopy rests over the frame. The machine's pivot arrangement gives the wheel loader the ability to work in small turning circles.
