Abstract

L'invention concerne un système d'ascenseur (1) comprenant un support de cabines (2) apte à se déplacer dans un espace de déplacement (3) destiné au passage du support de cabines (2). Une première cabine d'ascenseur (15) est reliée indirectement au support de cabines (2), et une deuxième cabine d'ascenseur (16) est disposée sur le support de cabines (2). De plus, des éléments de réglage hydrauliques (25, 26) et des éléments de retenue hydrauliques (29, 30) permettent le réglage et la retenue de la deuxième cabine d'ascenseur (16) par rapport au support de cabines (2). A cet effet, aux fins de réglage de la deuxième cabine (16) par rapport au support de cabines (2), les éléments de réglage hydraulique (25, 26) exercent sur la deuxième cabine (16) une force de réglage agissant dans une première direction (20). Et les éléments de retenue hydrauliques (29, 30) exercent, dans une deuxième direction (21), une force de retenue sur la deuxième cabine d'ascenseur (16). Ladite deuxième direction (21) est opposée à la première direction (20).
