Abstract

L'invention concerne un ascenseur comportant: un palan disposé sur un contrepoids (120) pour contrebalancer le poids d'une cabine (201) au moyen d'une corde (213), le palan faisant monter et descendre la cabine avec la corde (201) et comprenant un moteur d'entraînement (105); une poulie de traction (103) dotée d'un arbre rotatif différent de celui du moteur d'entraînement et autour duquel est enroulée la corde ; et un dispositif (127) de transmission de puissance destiné à transmettre une puissance du moteur d'entraînement (105) à la poulie de traction (103). Même dans un ascenseur à charge importante, le moteur d'entraînement peut être de taille réduite puisque la charge de la cabine (201) n'a pas d'incidence sur le moteur d'entraînement (105).
