Claim 14:
15. A winch column system for supporting power transmission lines and static lines during repair or replacement of a power line existing pole, the winch column having a longitudinal axis, a front side, rear side, and right and left sides, the winch column system comprising:
a winch column main body comprising a lower beam adapted to be connected to a vehicle and held by the vehicle to be vertically adjacent to the existing pole, an upper beam, and a hinge connecting the lower beam and upper beam and being adapted for pivoting the upper beam to be parallel to the lower beam in a winch column in-use configuration, and to be folded to be side-by-side with the lower beam in a winch column transport configuration;
wherein, when the winch column is in the in-use configuration:
a frame is slidable up and down the upper beam, and is lockable in multiple positions on the upper beam, wherein the frame comprises lower arms extending forward and each having a sheave receiving a winch cable controlled by a winch mounted on the main body, and upper arms extending upward and each having multiple connection points;
wherein the winch cable of each of the lower arms is adapted for connection to a power transmission conductor, for supporting the conductor upon disconnection of the conductor from the existing pole, and moving of the conductor away from the existing pole and toward the main body, wherein each sheave comprises a load sensor for sensing the tension on the conductor; and
wherein the upper arms are each adapted to connect to one of the static lines for supporting the static lines, by hoist systems being attached to a selected one of the multiple connection points on each of the upper arms and being connected to one of the static lines;
wherein, when the conductors and the static lines are disconnected from the existing pole, the winch cables in the sheaves of the lower arms and the hoist systems connected to the upper arms support, and hold at a distance from the existing pole, the conductors and the static lines, respectively, so that the existing pole can be repairs or replaced.
