Abstract

L'invention concerne un système d'ascenseur (10) comprenant une cabine d'ascenseur (14), qui peut être déplacée dans une cage d'ascenseur (12) dans une direction verticale. À cet effet, le système d'ascenseur (10) comporte un moyen de support (26a) fermé, guidé autour d'une poulie de renvoi inférieure (28) et d'une poulie de renvoi supérieure (30), et une machine d'entraînement (34a) associée au moyen de support (26a). Afin de créer une liaison d'entraînement entre le moyen de support (26) et la cabine d'ascenseur (14), un appareil d'accouplement est agencé sur la cabine d'ascenseur (14), qui peut être accouplé à un élément d'accouplement (44.1a) du moyen de support (26a). Selon l'invention, l'élément d'accouplement (44.1a) du moyen de support (26a) est conçu sous la forme d'un élément de liaison, qui relie entre elles les deux extrémités libres du moyen de support (26a).
