In this equipment for the testing of a speed limiter, a wheel axle (5) of a drive wheel (6), which engages into a cable groove (7) of a cable guide roller (8) and drives this, is clamped into a drill chuck (4) of a drilling machine (1). The cable guide roller (8) is a component of the speed limiter to be tested. For testing the speed limiter, the limiter cable is taken off from the cable guide roller (8). Then, the cable guide roller (8) is driven at a linearly rising speed by means of the drive wheel (6) up to the triggering point of the speed limiter. The movement of the drive wheel (6) is detected and evaluated by means of an evaluating device (9) with an opti- electronic system (10) arranged at the drilling machine (1). Reflectors (11) arranged at the drive wheel (6) reflect light (12), which is emitted by the opti-electronic system (10) and picked up and evaluated in the form of light reflections (13) by the opti- electronic system (10). The speed of the cable guide roller (8) is increased by the drilling machine (1) by way of the drive wheel (6) up to the triggering point of the speed limiter. The triggering instant is detected by an acceleration sensor (16) connected with the speed limiter.
