Abstract
A winch column holds electric power conductors and static lines separate and distanced from an existing power line pole/structure during repair or replacement of the pole/structure. The winch column is temporarily anchored and stabilized to be vertical and adjacent to the existing pole/structure, and winch cables extend from the winch column height-adjustable frame to support the load of the disconnected conductors. Hoist lines also extend from the frame to support the disconnected static lines. After the repair or replacement of the pole/structure, the conductors and static lines are moved, and reconnected, to the new pole, and the winch column may be moved to another existing pole or power line or folded for storage. Whenever the winch cables handle the conductors, tension sensors provided on the frame are used to monitor and report conductor tension, for safe and effective handling and reinstallation on the new pole.
