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 and a compensating weight, which are for their part connected to support the elevator car by the aid of a suspension member, such as a rope or belt, and also a hoisting machine provided with a traction sheave, and one traction member, such as a belt, which is adapted to transmit the rotational movement of the traction sheave into movement of the elevator car and of the compensating weight, and also a tension control means, which is arranged to adjust the magnitude of the tension forces exerted on the suspension member and on the traction member. The arrangement comprises a tensioning means connected to the traction member, and the tension control means is connected to that part of the traction member that is on the side of the compensating weight with respect to the traction sheave, and the tensioning means is connected to that part of the traction member that is on the side of the elevator car with respect to the traction sheave.
