Special vacuum cup holders with double springing
All the special vacuum cup holders previously described can be provided in the double springing version.
The cup holder fixing bush is located between two springs: the lower one cushions the impact of the cup with the load to be lifted during the approach phase, while the upper one cushions the impact of the bush with the cup holder end and gradually loads the cup during the lifting phase.
These cup holders are especially recommended when the load to be lifted is very heavy, rough or not perfectly flat.
The actual springing stroke is:
- For height C= 55 mm 37 mm
- For height C= 110 mm 84 mm
