Basic vacuum cup holders
These cup holders are built in a simple and rational way, guaranteeing maximum sturdiness and duration.
They are composed of:
- A brass stem for fastening the cup;
- A steel threaded sleeve equipped with two hexagonal nuts for a quick assembly of the cup to the machine;
- A spring for cushioning the impact of the cup, as well as for maintaining a constant pressure with the load to be lifted;
- A quick coupling for the connection to the suction hose.
The actual springing stroke is:
- For height C= 28 mm 16 mm
- For height C= 65 mm 49 mm
- For height C= 95 mm 74 mm
