Further, the cage 4 has a larger frontage size and a heavier weight than in the first embodiment, and accordingly, the width of the counterweight 5 is larger. Other configurations are the same as those in the first embodiment. In this way, by arranging the first and second counterweight suspenders 31 and 32 side by side, when the width dimension of the counterweight 5 changes with the change of the dimension in the width direction of the car 4 This can be easily dealt with simply by changing the distance between the first and second counterweight / lifting vehicles 31 and 32.

Abstract

L'invention concerne un dispositif d'ascenseur grâce auquel la hauteur d'une cage d'ascenseur (1) peut être extrêmement réduite étant donné que l'on utilise au mieux un espace situé à l'intérieur de la cage d'ascenseur (1). Un poids d'équilibrage (5) est monté à l'arrière d'une cabine (4), et un dispositif d'entraînement (9) comprend un corps principal (10) et une roue à gorge d'entraînement (11) qui est entraînée par ledit corps principal (10). Le corps principal (10) est monté de façon à se chevaucher avec le coin arrière de la cabine (4), dans un plan en projection verticale. Le dispositif d'entraînement (9) est monté de telle sorte que l'axe de la roue à gorge d'entraînement (11) s'étende de façon inclinée par rapport à l'orientation de la façade de la cabine (4) (sens latéral montré sur la figure). Une première et une seconde roue de renvoi (17, 18) conduisant un câble principal (12) de la roue à gorge d'entraînement (11) à la cabine (4) sont montées horizontalement sur la partie supérieure, à l'intérieur de la cage (1), tout en étant séparées par un espace.
