Abstract (en)
[origin: EP2687473A1] Device for protecting against the uncontrolled movement of a lift car, which is suitable for being coupled to a speed limiter having a pulley (2) on a shaft (3), said device comprising: a ring gear (5) connected to the pulley; a pivoting support means (6) which can be coupled to the shaft (3), carries out a pivoting movement with respect to said shaft (3) and includes a blocking mechanism which acts on the ring gear (5) by means of an electromagnet, a solenoid or the like; and an electrical detector which is connected to the blocking mechanism and the movement trajectory of the pivoting support means (6) and, when the blocking means act on the ring gear (5), when the pivoting support means (6) has carried out an angular movement, the electrical detector sends an activation signal to a control unit connected to the lift in order to actuate means for stopping the lift car.
