Abstract (en)
[origin: EP1813566A1] A safety device for an elevator capable of reducing the time period required for stoppage of a car after detection of a speed abnormality of the car of the elevator. A brake element is provided between one side surface of a guide rail for guiding the car and a guide surface placed so as to be distanced away from one side surface of the guide rail along a downward direction, and an attraction portion which is attracted to the guide rail when a speed abnormality of the car is detected is provided on the brake element. When a speed abnormality of the car is detected, the attraction portion is attracted to the guide rail to stop the brake element from descending, and the brake element bites into the guide rail with a wedging effect to produce a braking force.
