Special vacuum cup holders with push valve
They share the same technical and mechanical features at the special vacuum cup holders. Their distinctive feature is the push valve on the cup support, which activates suction, and therefore creates vacuum, only when the cup is in contact with the load to be lifted.
With these cup holders, it is no longer necessary to install cocks on the suction hoses; for this reason, they are recommended in all those cases in which there is a chance that not all the cups come into contact with the load to be lifted (because of an uneven or incomplete load).
The same push valve can also be applied with no modification to the special articulated cup holders.
The actual springing stroke is:
- For height C= 55 mm 37 mm
- For height C= 110 mm 84 mm
