Centrifugal brakes allow controlled descent in the absence of motorisation and in case of breakdown of the holding brake. They do not allow uncontrolled acceleration of the load, and what would otherwise seem an inevitable accident becomes only an incident. Evidently both the holding brake and the centrifugal brake cannot avoid an accident if the anomaly is caused in the reducer or any element behind them. If the centrifugal brake is assembled with an independent transmission, it behaves as an end safety mechanism, as its action will be independent from whether a breakdown or breakage has rendered the holding brake or the reducer unusable.
