Summary:The object of the invention is an arrangement for adjusting the tautness of a traction member of an elevator, which arrangement comprises an elevator car (1) and a compensating weight (2), which are for their part connected to support the elevator car (1) by the aid of a suspension member (4), such as a rope or belt, and also a hoisting machine (3) provided with a traction sheave (3a), and one traction member (5), such as a belt, which is adapted to transmit the rotational movement of the traction sheave (3a) into movement of the elevator car (1) and of the compensating weight (2), and also a tension control means (8), which is arranged to adjust the magnitude of the tension forces exerted on the suspension member (4) and on the traction member. The arrangement comprises a tensioning means (9) connected to the traction member (5), and the tension control means (8) is connected to that part of the- traction member (5) that is on the side of the compensating weight (2) with respect to the traction sheave (3a), and the tensioning means (9) is connected to that part of the traction member (5) that is on the side of the elevator car (1) with respect to the traction sheave (3a). L'objet de l'invention concerne un agencement qui permet d'ajuster la tension d'un élément de traction d'un ascenseur, lequel agencement comprend une cabine d'ascenseur (1) et un contrepoids (2), qui sont pour leur part reliés pour supporter la cabine d'ascenseur (1) à l'aide d'un élément de suspension (4), tel qu'une corde ou une courroie, et également une machine de levage (3) pourvue d'une poulie de traction (3a), et un élément de traction (5), tel qu'une courroie, qui est conçu pour transmettre le mouvement de rotation de la poulie de traction (3a) en mouvement de la cabine d'ascenseur (1) et du contrepoids (2), et également un moyen de régulation de tension (8), qui est agencé pour ajuster l'amplitude des forces de tension exercées sur l'élément de suspension (4) et sur l'élément de traction. L'agencement comprend un moyen tendeur (9) relié à l'élément de traction (5), et le moyen de régulation de tension (8) est relié à la partie de l'élément de traction (5) qui est du côté du contrepoids (2) par rapport à la poulie de traction (3a), et le moyen tendeur (9) est relié à la partie de l'élément de traction (5) qui est du côté de la cabine d'ascenseur (1) par rapport à la poulie de traction (3a).
