PCT No. PCT/SE86/00338 Sec. 371 Date Apr. 3, 1987 Sec. 102(e) Date Apr. 3, 1987 PCT Filed Jul. 16, 1986 PCT Pub. No. WO87/01080 PCT Pub. Date Feb. 26, 1987.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.
