    Abstract: An arrangement for reducing the displacement of an elevator car caused by a change in loading includes at least an elevator car configured to move up and down in an elevator hoistway and one or more counterweights, and also at least one rope element above the elevator car and at least one rope element below the elevator car and at least one pretensioner of the rope elements. The elevator car and counterweight are configured to be supported and moved via the rope elements and the pretensioner and rope pulleys, of which rope pulleys the first part are diverting pulleys, and the second part are traction sheaves. The arrangement additionally includes at least two hoisting machines. In the arrangement is a mechanism configured to lock at least two rope pulleys to be non-rotating at least during loading of the elevator car.
