Abstract

L'invention porte sur un dispositif d'ascenseur, dans lequel dispositif une cabine est suspendue à partir d'un moyen de suspension, et est élevée et abaissée dans un trajet d'élévation/abaissement à l'aide d'un treuil. Dans le trajet d'élévation/abaissement, un corps de guidage de secours est disposé, lequel s'étend le long de la direction d'élévation/abaissement de la cabine. Un dispositif de secours dans la cabine qui fait se déplacer la cabine le long du corps de guidage de secours est monté dans la cabine. Le dispositif de secours dans la cabine a un corps rotatif de secours qui tourne à l'aide d'un actionnement à partir de l'intérieur de la cabine, et qui vient en contact avec/est séparé vis-à-vis du corps de guidage de secours. Par le fait que le corps rotatif de secours est tourné tandis que le corps rotatif de secours est dans l'état de contact avec le corps de guidage de secours, la cabine est déplacée le long du corps de guidage de secours.
