“Manzoni” Mechanical Press – Weight: 18.000 Kg – Power: 200 ton. – Type of activity: stamping metal parts. The machine couldn’t work faster than 40 strokes per minute, because its vibrations disturbed its surrounding (the glasses, other machines, the roof and the other parts of the building). The model of QUIVERDAMPER selected was M180.
