Pneumatic Suction Cups
These suction cups are mounted on pneumatic cylinders that raise them above the roller tracks and only operate when the ball shutter valve is squeezed by the panel surface. Suction cups that aren’t under the wooden panel do not activate
Suction cups that are under the wooden panel, on the other hand, function like clamps and keep the panel firmly in place. Note in the video how the operator tries to move the panel manually once hooked, without result.
