Abstract

La présente invention concerne un dispositif de compensation d'allongement de câble principal pour ascenseur. Une poulie à gorge rotative de réglage (6), qui vient en contact avec un câble principal (3), est placée mobile entre une poulie motrice (1a) et une roue de déviation (2). Etant donné que la poulie de réglage (6) peut se déplacer, la longueur du câble principal (3) entre la poulie motrice (1a) et la roue de déviation (2) est modifiée de façon à compenser l'allongement du câble principal (3).
