FIELD: transport.
SUBSTANCE: invention relates to elevator safety devices. This device can decelerated the elevator at its spontaneous displacement. this device comprises frame arranged at elevator cabin one side for guide rail to pass there through unobstructed. Lifting wire cable gets tensioned subject to elevator cabin motion. First locked pulley is secured at said frame while its lower part is enclosed by lifting wire cable. Movable pulley top part is enclosed by lifting wire cable after exiting the locked pulley bottom part. Movable pulley runs up and down subject to lifting wire cable tension. Besides, it includes lifting guide to direct said movable pulley. First guide element is connected with the lifting cable end to displace in opposite direction simultaneously with movable pulley motion. First brake means can turn at a time with first guide element up and down motion.
EFFECT: higher reliability of elevator braking.
