METHOD AND DEVICE TO ACTUATE ELEVATOR CAB CATCHERS Russian patent published in 2010 - IPC B66B5/04 

FIELD: transport.

SUBSTANCE: proposed device comprises speed limiter decelerating cable 122 that, when decelerated, actuates catchers. Catcher actuator 120 is arranged between speed limiter cable 122 and elevator cab 110 connected with two ends (122a, 122b) of said cable (122) and secured to elevator cab (110). Two ends (122a, 122b) of said cable (122) are secured on movable parts (124, 126) of catcher actuator (120). Proposed device actuates catchers by tensioning speed limiter cable or in the case there is no said tensioning. Proposed device and method allow, in the of cable breakage or tensioning force falling beyond tolerances, changing catcher actuator from normal operating state into that of actuation. Note here that catcher actuator braking lever 140 changes catcher actuator from normal operating state into that of actuation.

EFFECT: higher operating safety.
