Abstract

L'invention concerne un dispositif d'ascenseur qui peut rendre inutile le réglage des positions mutuelles d'une unité de réglage de position de palier et d'une unité de détection de position de palier et qui peut raccourcir le temps de remplacement en simplifiant le travail de remplacement d'une unité de détection de position de palier. Une unité de réglage de position de palier (24) est disposée sur une première plaque de protection (23) fixée sur un seuil côté montée (21), et une unité de détection de position de palier (26) est disposée sur une deuxième plaque de protection (25) fixée sur un seuil côté cabine (22). Du fait que l'unité de réglage de position de palier (24) est disposée sur la première plaque de protection (23) fixée sur le seuil côté montée (21) qui sert de référence de positionnement et que l'unité de détection de position de palier (26) est disposée sur la deuxième plaque de protection (25) fixée sur le seuil côté cabine (22) qui sert de référence de positionnement, le réglage des positions mutuelles de l'unité de réglage de position de palier (24) et de l'unité de détection de position de palier (26) peut être rendu inutile. De plus, en déplaçant une cabine de passagers (11) jusqu'à une distance prescrite, la deuxième plaque de protection (25) peut être exposée à la plateforme de montée (27) et l'unité de détection de position de palier (26) peut facilement être remplacée depuis la plate-forme de montée même si l'unité de détection de position de palier (26) est endommagée.
