Abstract

A load alternation counting device for an actuation device that is periodically hydraulically loaded has a cylinder and a piston sealingly positioned within the cylinder and axially displaceable therein. A pressure connector is provided for connecting the cylinder to a hydraulic loading device of the actuation device such that the piston is axially loaded when hydraulic loading of the actuation device occurs. A counter is switchable by an axial displacement of the piston within the cylinder. A spring for biasing the piston in a direction away from the counter is provided. The spring has a spring force such that switching of the counter by the axial displacement of the piston occurs only when a preset hydraulic pressure is surpassed.
