PROBLEM TO BE SOLVED: To obtain a pull wire extension system in which enhancement in the safety of pull wire extension work, enhancement in reliability and enhancement of economy are made compatible, and to obtain an extension method of stringing.SOLUTION: A pull wire extension system includes: an auxiliary line 10 constituted relatively thinner and lighter than the pull wire, and connected with the pull wire when it is extended; a weight 20 connected to the vicinity of one end of the auxiliary line 10; and a multicopter 30 provided with a support mechanism 32 for supporting an annular body 22, i.e., at least one of the weight 20 or the auxiliary line 10 in the vicinity thereof, and capable of flying between a first tower and a second tower. The support mechanism 32 has: a movable hook 34 (remote separation mechanism) capable of separating the annular body 22, supported by remote operation, from the multicopter 30; and a stationary hook 36 (automatic separation mechanism) capable of separating the annular body 22 automatically from the multicopter 30, when the auxiliary line 10 is pulled with a predetermined tensile force or more.SELECTED DRAWING: Figure 4
【課題】呼び線の延線作業の安全性の向上、確実性の向上及び経済性の向上を両立させる呼び線の延線システム及び架線の延線方法とする。【解決手段】呼び線よりも相対的に細くて軽く構成され呼び線を延線する際に呼び線に接続される補助ライン10と、補助ライン10の一端の端部近傍に接続される重り20と、重り20又は重り20の近傍の補助ライン10の少なくとも一方である環状体22を支持する支持機構32が設けられており第1鉄塔と第2鉄塔の間を飛行可能なマルチコプター30と、を備え、支持機構32は、遠隔操作により支持している環状体22をマルチコプター30から分離可能な可動フック34(遠隔分離機構)と、補助ライン10が所定張力以上の張力で引っ張られた場合に環状体22をマルチコプター30から自動的に分離可能な固定フック36(自動分離機構)と、を有する。【選択図】図4
