method and device for testing a geschwindigkeitsbegrenzers a aufzugsanlage

摘要

The testing system uses an electric drill (1) acting as part of a drive device (1,2..6) for rotating a cable deflection roller (8) of the velocity limiter. The cable deflection roller is rotated at a constantly increasing velocity by the drive device until the release point of the velocity limiter is reached. The rotation rate of the drive wheel (6) for the cable deflection roller is detected via an optoelectronic device (10), attached to the drill, together with an evaluation device, with the release of the velocity limiter detected via an associated acceleration sensor (16).
