Abstract

Ascenseur doté de mains-courantes sur une cage. Les mains-courantes peuvent être déplacées d'une position verticale où les mains-courantes sont mises en position debout sur la cage à une position d'exploitation normale plus basse que la position verticale. Un dispositif d'entraînement pour soulever/abaisser la cage est disposé au niveau d'une partie supérieure dans la gaine d'ascenseur de façon à se superposer aux mains-courantes dans le plan de projection verticale. Durant les opérations de maintenance, un moyen de détection de position d'arrêt pour la maintenance détecte que la cage s'est déplacée dans la gaine d'ascenseur à une position spécifiée d'arrêt pour la maintenance.
