In an elevator system comprising an elevator car, a counterweight, a set of elevator suspension ropes on which the elevator car and the counterweight are suspended, a traction sheave whose motion is transmitted via the suspension ropes to the elevator car and to the counterweight, a compensating system includes a set of compensating ropes connected to the elevator car and the counterweight via at least one diverting pulley. A vertically adjustable buffer arrangement mounted in conjunction with the counterweight allows the system to compensate for changes in the length of the suspension and compensating ropes. The suspension ratio of the compensating ropes is an integer multiple (i.e. 1, 2, 3 etc) of the suspension ratio of the suspension ropes. Finally, the rope suspension ratio on the side of the elevator car can be the same as that of the counterweight, or it may be different.
Système d'ascenseurs comprenant : une cabine d'ascenseur, un contrepoids, un jeu de câbles de suspension d'ascenseur supportant la cabine et le contrepoids; une poulie de traction dont le mouvement est transmis à la cabine et au contrepoids par le biais des câbles de suspension; un système de compensation muni d'un jeu de câbles de compensation reliés à la cabine d'ascenseur et au contrepoids à l'aide d'au moins une poulie de déviation. Un amortisseur ajustable vertical installé en conjonction avec le contrepoids permet au système de compenser les changements de longueur des câbles de suspension et de compensation. Le rapport de suspension des câbles de compensation est un multiple d'un nombre entier (par ex. 1, 2, 3, etc.) du rapport de suspension des câbles de suspension. Le rapport de suspension du câble du côté de la cabine d'ascenseur peut être identique à celui du contrepoids, ou différent.
