Abstract

La présente invention concerne un escalier roulant dans lequel une structure en peigne s'engrenant avec les attaches d'une marche est montée sur un palier. Un limitateur d'inclinaison est monté sur un châssis. A proximité du palier, ce limitateur d'inclinaison fait face à la partie inférieure d'une section de montage de rouleaux d'entraînement. Si la section de montage de rouleaux d'entraînement se déplace vers le bas en raison d'une anomalie d'un rouleau d'entraînement, le limitateur d'inclinaison reçoit ladite section de montage de rouleaux d'entraînement pour limiter l'inclinaison du corps de la marche.
