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.
