FIELD: transport.
SUBSTANCE: invention relates to elevator protection electronic system. Elevator system comprises cabin 16, counterweight, drive device, ropes 12, tachometer 42, accelerator 44, mechanical catcher, electromagnetic starter 46, and controller 48. Controller 48 serves to unlock electromagnetic starter 46 to interact with mechanical catcher when tachometer 42 or accelerator 44 outputs signal about excess speed or acceleration of cabin 16 or counterweight. Electromagnetic starter 46 is automatically reset.
EFFECT: higher safety.
