Abstract
A cab suspension system is provided for a yard tractor having tiltable cab with a laterally offset center of gravity which maintains the cab at lateral level, controllably adjusts the longitudinal level, and unlatches and raised the cab in one operation. The system preferably includes a pair of adjustable air sleeve springs disposed between the cab and the tractor frame with one of the springs being larger than the other and disposed on the enter-of-gravity side of the cab; and a hydraulically operable latch coupling the cab with the springs. In use, the configuration of the springs maintains the lateral level of the cab, the tractor driver adjusts the springs' air pressure for longitudinal level, and actuation of the hydraulic system unlatches the cab from the springs and tilts the cab upwardly.
