Functional principle on the example of PClamp N
PClamp N open
PClamp works on the principle of the spring accumulator: In normal operation, an air chamber between two spring plates is pressurized with compressed air. Due to the air supply, the spring plates bulge, shorten and thus release the rod.
PClamp N clamped
In case of failure of the pneumatics, the air chambers between the spring plates are vented. The spring plates return to their original position, press the clamping bush against the rod and fix them securely and with great force in their position.
