<p>PURPOSE:To perform electric wire shifting work more easily and safely from a wire drawing metal wheel to a suspension clamp in wire tensioning work by installing a temporary arm above an insulation arm at the top level and by lifting an electric wire with a wire lifting hook attached to a wire rope put through a scaffolding metal wheel at the tip of said temporary arm. CONSTITUTION:A base portion of a temporary arm 31 is supported by a suspension support 28, the tip side of said arm 31 is extended to a position directly above an electric wire 6 to be erected or slightly outwardly from said wire, and said temporary arm 31 is attached to the suspension support 28 above an insulation arm 23 at the top level. Then, a scaffolding metal wheel 32 is attached to the temporary arm 31 at a position directly above or at an outer position of the electric wire 6 to be erected, and the electric wire 6 is lifted by a wire lifting hook 34 attached to the tip of a wire rope 35 passed through the scaffolding metal wheel 32. By doing this, for instance, the shifting of the electric wire 6 from a wire drawing metal wheel 25 to a suspension clamp in the wire tensioning work can be performed easily and safely.</p> |
