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.
