Abstract

L'invention concerne un système d'ascenseur dans lequel un moyen de suspension de type courroie est guidé par l'intermédiaire d'au moins un galet. Selon l'invention, une surface de contact du galet présente une structure anisotrope de manière à coopérer avec le moyen de suspension de type courroie. Un coefficient de frottement entre le moyen de suspension et la surface de contact dans la direction circonférentielle du galet est supérieur à un coefficient de frottement entre le moyen de suspension et la surface de contact dans la direction axiale du galet.
