<p num="1"><br/><br/> ABSTRACT<br/> The invention relates to a cable tensioning device for<br/>ski lifts or aerial cableways of the kind comprising an end-<br/>less transporting cable(1) extending between two rotatable<br/>wheels(2) mounted on carriers(4), at least one of the wheels<br/>being movable by the fact that its associated carrier is<br/>slideably movable relative to a foundation in order to keep<br/>the cable tensioned. The carrier(4) is by means of a nut<br/>device connected to a suitably rotatable screw(13). A tension<br/>sensing device is associated to a power source(19) for<br/>causing a rotating relative movement between the screw(13)<br/>and the nut device in order to,at an occurred change in the<br/>tension of the cable(1),start the power source(15) and effect<br/>a movement of the wheel(2) in question a distance relative<br/>to the foundation that corresponds to the actual tensional change.<br/>Fig. 1.<br/> |
