Pneumatic System

The pneumatic system is designed for driving and control of some rig mechanisms. The pneumatic system is fed from vehicle pneumatic system.

From pneumatic line the air is supplied to the air-control valve No.1 (Drawing 16) for air fork functioning and to the electropneumatic valve (2) for the PTA actuation.
The PTA actuation is controlled with the toggle switch located in the cab.
