Abstract

Perfeccionamietnos introduced in safety devices for elevators, forklifts and the like, characterized in that they comprise means that respond to the speed of the elevator, arranged to be activated when the elevator moves at a speed higher than previously determined, with which this activation causes a wheel to rotate at a speed corresponding to the speed of the elevator, said wheel having a plate against which one or more brake shoes comes into contact, comprising a brake pad on each side of a plate, as well as means for pushing the brake pads against said plate.
