Before the development of hydraulics, chain-driven mechanisms were the upfitting norm as this photo from the 1930s demonstrates. While it may not be as efficient as the modern technology, the evidence shows that it still got the job done.

The upfit was completed by the Auto Truck Group, which has been in business for nearly a century in the Chicago market. Founded in 1918, the Auto Truck Group is headquartered in Bartlett, Ill.
