Special vacuum cup holders with built-in shut-off valve

Along with all the other features they share with the other special cup holders, these also have a built-in shut-off valve.
The purpose of the shut-off valve is to automatically close suction when the cup is not in contact with the surface of the load to be handled or in case of a faulty grip or of considerable transpiration. This thus prevents the reduction of the level of vacuum on the remaining cups of the system which are regularly handling the load.
The clear advantage of this system is that the positioning or the exclusion of the non-gripping cups are no longer binding. Cups with diameters between 85 mm and 150 mm can be assembled onto these cup holders, as long as they are provided with a threaded 3/8” gas female support.
The actual springing stroke is:
- For height C= 55 mm 37 mm
- For height C= 110 mm 84 mm

Special articulated cup holders with compact stroke

Marble and glass sheets are usually handled with cups that take them from a horizontal plane and place them vertically or vice versa. These special cup holders with compact stroke have been designed to minimise the lever forces between the cup and the machine fixing bush during the rotation of the sheets, as well as their sliding on the cups.
They share all the technical features of the other special cup holders but their overall dimensions are reduced to the minimum, by housing the articulated joint in the cup support, thus reducing the steel stem and the spring stroke length and modifying the brass bush, in order to allow it to be screwed directly onto the machine.
Moreover, a special non-slip plastic coating fixed onto the cup support prevents the lifted load from slipping.
