Abstract

Dans un dispositif d’ascenseur, une cabine est suspendue sur un côté d’une poulie de traction par des moyens de suspension et un contrepoids est suspendu par les moyens de suspension sur l’autre côté. Un dispositif d’arrêt d’urgence est monté sur la cabine pour arrêter en urgence la cabine en entrant en prise avec un rail de guidage de cabine. Lors d’un essai de contrôle du fonctionnement du dispositif d'arrêt d'urgence, un dispositif d'application d'une force de retenue applique une force de retenue à la partie des moyens de suspension qui se trouve du côté du contrepoids de la poulie de traction, la force de retenue appliquée étant inférieure à une charge de déséquilibre entre la cabine et le contrepoids.
