This paper shows the determination of tightening weight travelling distance for the zipline. A rope for a zipline can be fixed at both ends, or it can be fixed at one end and tightened with a weight at the other. A both-sided anchorage is simpler to perform, but there is a problem with large changes in the rope force due to temperature differences and due to the movement of the load on it. With a rope that is fixed at one end and tightened with a weight at the other end, there are no such problems, because the force in the rope is always the same, but care must be taken to ensure sufficient travel of the tightening weight. The required travel of the weight is affected by temperature changes, ice buildup and snow, but also by the movement of passengers on the rope itself. Formulas based on which the weight movement is calculated are derived in the paper.
