Abstract

Ascenseur (1) qui possède en tant que moyen de support et d'entraînement au moins une courroie (11) pourvue d'un dispositif de guidage par courroie 2:1. Lorsque l'entraînement linéaire (12) mécanique placé latéralement dans la tête (2.1) de cage fait avancer la courroie d'une unité par enroulement autour d'une roue d'entraînement (13), la cabine d'ascenseur (3), ou plus précisément le contrepoids, se déplace d'une demi-unité. L'une des extrémités de la courroie (11) est fixée à un premier point fixe (14) de courroie et la seconde extrémité de la courroie (11) est fixée à un second point fixe (15) de courroie. La courroie (11) est guidée sur une première poulie de déviation (16), sur une poulie profilée (17), sur une deuxième poulie de déviation (18), sur une troisième poulie de déviation (19), sur la roue d'entraînement (13) et sur une quatrième poulie de déviation (20). Des poulies de déviation (22) de l'entraînement linéaire (12) déterminent l'angle d'enroulement de la courroie (11) sur la roue d'entraînement (13).
