<p>The invention relates to an apparatus and system for detecting overspeed of elevator components such as a car or a counterweight having: a wheel, with an auxiliary surface or auxiliary wheel (100), configured to run on a first surface (210) of a travel rail (200) of the elevator component; an actuating device for actuating a braking mechanism of the elevator component; a speed detection device for generating a synchronized alternating movement with the speed of the elevator component; the speed detection device being configured to not generate the synchronized alternating movement when a predetermined speed of the elevator component is exceeded and to thus activate the actuating device (300). In the system of the invention, the apparatus can be arranged in an upper or lower part of the elevator component. In the first case, the transmission device has a plurality of levers (910); in the second case, it has pinions (920) and chains.</p> |
