Abstract

L'invention concerne un ascenseur pourvu d'un treuil dans la partie inférieure d'une cage. Une ligne droite inter-rails reliant une paire de rails de guidage de cage, passe par le centre de gravité de ladite cage ou par une position proche dudit centre de gravité, dans un plan de projection horizontal, une ligne droite située dans le même plan, qui relie une paire de poulies de suspension de cage étant inclinée par rapport à la ligne droite inter-rails, de manière à couper ladite ligne par le centre de gravité de la cage ou dans une position proche dudit centre de gravité. Le treuil placé de sorte que son axe s'étende dans un sens longitudinal, est incliné dans le même plan et dans le même sens que la poulie de suspension qui relie la ligne droite à la ligne inter-rails, ce qui produit une zone de maintenance sur le côté du treuil le plus proche de la poulie de suspension reliant la ligne droite.
