Abstract

Braking device for lifting means, such as lifts or goods lifts, comprising two braking means (1,3), acting simultaneously. One of said braking means (1) is an asynchronous alternate current motor, with one speed, supplied with direct current. The other braking means (3) is an electromagnetic brake which exercises an action of intemittent intervention. The asynchronous motor (1) is connected to the manoeuvring winch (2) of the lift (6) by the electromagnetic brake (3).
