Abstract

A manually operated press comprises an actuation lever coupled to a shaft assembly. An actuation of the actuation lever is transformed into a stroke movement of a press ram. A clutch assembly is provided for interrupting a flow of force between the actuation lever and the press ram. The clutch is adapted to separate an input shaft from an output shaft depending on predetermined pressing parameters. The input shaft extends as an inner shaft through the output shaft. The clutch assembly has a first clutch designed as a stroke stop for immobilizing the input shaft with a press housing depending on the pressing parameter, and a second clutch designed as an overload clutch for interrupting a flow of force between the input shaft and the output shaft.
