Title
(EN) ELEVATOR DEVICE
(FR) DISPOSITIF D'ASCENSEUR
(JA) エレベータ装置
Abstract
(EN)
Disclosed is an elevator device that is capable of preventing a main rope driven by a hoisting machine from making a movement such as rotation and twisting. This elevator device is provided with: an elevator car (102); a main rope (103) connected to the elevator car; pulleys (106, 107) over which the main rope is to be placed; and a hoisting machine (105) which drives the main rope, wherein a contact interface between the main rope and each pulley is provided with a means that prevents a cross-section of the main rope in a direction perpendicular to the axis of the main rope from moving around within a groove of the pulley.
(FR)
L'invention concerne un dispositif d'ascenseur qui est capable d'empêcher un câble principal, entraîné par une machine de levage, de réaliser un mouvement tel qu'une rotation et une torsion. Ce dispositif d'ascenseur comprend : une cabine d'ascenseur (102) ; un câble principal (103) relié à la cabine d'ascenseur ; des poulies (106, 107) sur lesquelles doit être placé le câble principal ; et une machine de levage (105) qui entraîne le câble principal. Une interface de contact entre le câble principal et chaque poulie est pourvue d'un moyen qui empêche une section transversale du câble principal dans une direction perpendiculaire à l'axe du câble principal de se déplacer autour d'une rainure de la poulie.
