Disc Handwheels w/Safety Cylinder Grips

The handwheels can be secured using a transverse pin or by parallel key connection together with a DIN 6912 socket head screw and a DIN 7349 washer.
Two steps have to be carried out to bring the cylindrical safety grip into operating position:
- Swivel the grip around the axis of rotation until it stops (90°).
- Push grip in axial position into locking position.
The pressed-in position is the most comfortable position to crank. When released, the grip automatically returns to original position.
