Überlastsicherung für schneller laufende Pressen

Usually crank as well as eccentric presses are equiped with hydraulic overload safety devices to protect them against overloads. But the number of strokes of those devices is limited up to 50 per minute. They are to slowly to be used in state of the art. High speed presses are working with more than 300 strokes per minute. A sensor controlled overload safety device for application in high speed presses was developed at the Fraunhofer-IUW in Chemnitz/Germany.
