Air Bellow Drive
The pantograph is raised with the air bellow drive. The air bellow drive is mounted
between base frame and lower frame.
The force of the bellow is transmitted by cables which are running in cams. The air
bellow drive is connected with the valve unit ADD with a compressed air hose.
All compressed air settings for the air bellow drive can be adjusted with the
pneumatic control.
There is an uplift-stop mounted inside the air bellow drive, which prevents the
pantograph from raising above maximum extension.
