Abstract

Improvements in safety devices for elevators and the like, and more particularly in automatic emergency re-leveling devices for elevator cars, characterized in that an emergency driving circuit of the car comprises emergency control means (25) for the cab, of relatively low power, arranged to drive a winch (35) to perform vertical movements of the car (8), said means (25) being capable of being automatically activated as a result of an accidental stop of the car (8) between two floors served by the elevator and to effect the re-leveling of the cabin to one of said two floors by means of the displacement of the cabin in the direction that originates power needs that are within the capacity of said means (25) of low power.
