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