Cab Air Suspension
CAB AIR SUSPENSION
THEORY OF OPERATION
The cab has air ride suspension. The air ride
suspension has twin air bags that are filled with
compressed air from the air system. A height control
valve regulates the amount of air pressure in the air
bags.
A lateral control rod keeps the cab located in the center
of the machine while allowing the cab to move up and
down. There are two shock absorbers that control the
bounce of the cab.
The front of the cab is mounted in rubber bushings to
allow the cab to move and pivot with the suspension.
FIG. 1: Cab air suspension (1) is located at the rear of
the cab.
