Claim:
A system for installing wires for a wire-climbing lifting device on a hollow tower, comprising: a fixed turning roll disposed inside a lower part of the hollow tower, which moves a rope linked to the turning roll when the turning roll is activated; a fixed pass-through device which is disposed outside a top of the hollow tower; a fixed structural support disposed near the pass-through device outside the hollow tower; a wire for the wire-climbing lifting device to climb, the wire having a first end and a second end; a wire terminal linked to the first end of the wire and linked to the rope; and a counterweight linked to the second end of the wire; wherein in a resting position the rope is completely rolled around the turning roll, the wire is disposed within the hollow tower, the wire terminal is at ground level, and the counterweight is in contact with a bottom surface of the structural support, and wherein in a maintenance position the rope is unrolled from the turning roll, the wire is disposed outside the hollow tower, the wire terminal is in contact with a top surface of the structural support, the counterweight is at the ground level, and the wire-climbing lifting device is attachable to the wire.
