Westinghouse Air Brake Company
The original Unimog was offered with a pneumatic system. This system was used for powering all auxiliary devices as well as the three-point linkages. As of October 1961, a hydraulics system became an option, and as of 1963, the hydraulics system became standard, but unlike the pneumatics system, the hydraulics system was made by Westinghouse Air Brake Company in Hannover. With the introduction of the hydraulics system, the pneumatics system was solely used for operating the brakes.
