Claims

[Scope of Claim for Utility Model Registration] In a wire extension vehicle equipped with a back tension device that can freely unwind an electric wire suspended from a brakeable capstan device with a required tension and that can freely apply back tension to the wire, the above-mentioned The back tension device is attached to the entry side of the capstan device, and applies adjustable and constant back tension to the electric wire, and at least one of the pulleys that clamps the electric wire,
1. A wire rolling wheel equipped with a back tension device, characterized in that it transmits either a pressing force that increases the resistance of wire drawing, or a rotational force in a direction opposite to the direction in which the pulley rotates due to wire drawing.
