The finding concerns a safety stop mechanism, to be mounted on lifting platforms, which forces the mobile lifting plane to stop, when its correct operation is compromised, due to the breaking of one of the control elements of said plane, in particular of the rotary pinion (103) that, acting in collaboration with a rack fixedly connected to the fixed part of the structure, controls the lifting and lowering movements of the platform. Such a device is of the type in which it is foreseen for a safety stop mechanism (100) to be made up of a rotary drum, on which an immediate stop lever mechanism acts, provided with a clutched disc brake, fixedly connected to the pin (102) that supports said pinion. Such a safety stop mechanism (100) is of the type that foresees that the clutched disc brake and the pin (102), which supports a rotary pinion (103), constitute two separate elements, which are mutually connected together through the interposition of a device (1), which has a damping function of the vibrations that are generated in the case of the lifting plane immediately stopping.
