L'invention concerne un dispositif de levage, en particulier un ascenseur ou une plate-forme de levage, comprenant une unité d'entraînement pour le levage au moins partiellement vertical d'un support de charge, l'unité d'entraînement comprenant au moins un moteur d'entraînement (14) et un arbre d'entraînement (11), au moins un élément de traction (23) sollicité en traction étant disposé au moins entre l'unité d'entraînement et le support de charge, au moins une unité de support (9, 10) étant prévue pour supporter au moins le moteur d'entraînement (14), l'unité d'entraînement comportant au moins une unité de démultiplication qui comprend l'élément d'entraînement (11) et au moins un élément de sortie (20) disposé sur un arbre de sortie (3), l'unité de démultiplication étant réalisée sous forme de dispositif de transmission par lien souple comprenant au moins un lien souple (15) entourant l'arbre d'entraînement (11) et l'élément de sortie (20), au moins un premier dispositif palier (16) pour le montage rotatif de l'arbre d'entraînement (11) étant disposé entre le moteur d'entraînement (14) et le lien souple (15), le lien souple (15) étant disposé entre le premier dispositif palier (16) et un deuxième dispositif palier (12) pour le montage rotatif de l'arbre d'entraînement (11). Le dispositif de levage selon l'invention est, par rapport à des dispositifs de levage selon l'état de la technique, nettement plus économique, et réalise en particulier un mode de fonctionnement considérablement plus économique. Cet objectif est atteint selon l'invention par le fait qu'au moins un moyen de support (13) pour le support et/ou l'appui du deuxième dispositif palier (12) par/sur l'unité de support (9, 10) est disposé entre le deuxième dispositif palier (12) et l'unité de support (9, 10) et par le fait que le moyen de support (13) est disposé entre l'arbre d'entraînement (11) et l'élément de sortie (20).
