Abstract
A device for de-icing power cables consisting of one or more wheeled dollies mounted for rolling movement along a cable, being movable along the cable by 'loping' of the cable in wind when ice has formed on the cable, and having scrapers thereon capable of removing ice from the cable, and arms affixed transversely to the cable at intervals therealong and having unequal weights carried at their extended ends, the arms serving as stops to limit the rolling movement of the dollies, and by rocking movement thereof induced by wind, to apply torsion to the cable to loosen ice formed on the cable.
