Abstract

Ce dispositif de sécurité (31) permet de travailler sur une cage d'ascenseur et comprend une plaque de détection (33) qui peut être déplacée vers le haut par une pression appliquée à partir du bas et est suspendue dans la gaine de l'ascenseur (1). Cette plaque de détection (33) est placée entre un dispositif d'entraînement (21) et la cage (5) de manière à permettre les travaux d'entretien du dispositif d'entraînement (21) situé au-dessus de la cage. Un élément tampon (35) est fixé sur la surface inférieure de la plaque de détection (33). Le déplacement vers le haut de cette plaque (33) est détecté par plusieurs commutateurs de détection (34). Si l'un au moins de ces commutateurs de détection (34) est actionné, du fait du déplacement vers le haut de la plaque de détection (33), la montée de la cage est stoppée par un circuit d'arrêt (40).
