Problems solved by technology

The problem with adjusting at intervals is that the traction member may be at the wrong tension for a long time between adjustments
This is especially problematic in elevators with large travel heights (where the elongation is relatively long)

Embodiment Construction

[0015] An elevator installation achievable by means of the arrangement according to the invention comprises at least an elevator car 1 adapted for reciprocating movement in an elevator shaft and at least one or more compensating weights 2, said elevator car 1 and compensating weights 2 As such is connected to support the elevator car 1 by means of suspension members 4, such as belts or ropes, and also by means of diverting pulleys 6 and 7 (eg mounted on bearings at the top of the elevator shaft). Whenever only one compensating weight is mentioned hereinafter, it is intended to mean simultaneously one or more compensating weights, or alternatively one or more counterweights. Furthermore, the device according to the invention also comprises a traction machine 3 provided with at least one traction sheave 3a or corresponding means and located in a machine station arranged at the bottom of the elevator shaft; and at least one or more traction members 5, such as belts or ropes, adap...

Abstract

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 atension 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).

Description

technical field [0001] The object of the invention is a device for adjusting the tension of an elevator traction member as defined in the preamble of claim 1 . Background technique [0002] In some elevator installations, the suspension members of the elevator car, such as suspension ropes, and the traction members of the elevator car are separated from each other. Usually, in this case, for practical reasons, the traction machine is arranged on the floor of the elevator shaft or close to the bottom of the elevator shaft, and for example toothed belts or other belts suitable for the purpose can be used as traction means , these traction members are mounted below the elevator car and one or more compensating or counterweights. In elevators of this type, the stresses exerted on the suspension members and traction members vary inter alia with changes in the load in the elevator car. From the viewpoint of normal operation of the elevator, it is desired that the stress distribu...
