PROBLEM TO BE SOLVED: To provide an installation method of a spiral cable hanger which makes wound preservation of a linear coated steel wire compact, improves preservation efficiency and is extremely convenient for conveyance by not forming the spiral cable hanger in a factory beforehand but inserting the linear coated steel wire carried into an installation site into a support line tensed in an installation block while molding it into a spiral shape by means of a spiral cable hanger molding device on the installation site.SOLUTION: A spiral cable hanger molding device 1 is configured to lead a linear coated steel wire 2 into the device 1 and feed it out of the device 1 while molding it into a spiral cable hanger 3. The spiral cable hanger molding device 1 is provided on an installation site, the spiral cable hanger 3 which is molded into a spiral shape and fed out by the spiral cable hanger molding device 1, is entangled at one end side of a support line 4 which is tensed in a required block beforehand, and fed to another end side of the support line 4. 【課題】螺旋状ケーブルハンガーを予め工場で形成するのではなく、架設現場に持ち込まれる直線状被覆鋼線を、架設現場で螺旋状ケーブルハンガー成形装置により螺旋状に成形しながら、架設区間に張架された支持線に挿入することにより、直線状被覆鋼線の巻取り保管がコンパクトで、保管効率が良く、搬送に非常に便利となる螺旋状ケーブルハンガーの架設方法を提供すること。【解決手段】直線状被覆鋼線２を装置１内に引き込んで螺旋状のケーブルハンガー３に成形しながら装置１外へ送り出す螺旋状ケーブルハンガー成形装置１を架設現場に備え、螺旋状ケーブルハンガー成形装置１により螺旋状に成形されて送り出される螺旋状ケーブルハンガー３を、所要区間に予め張架された支持線４の一端側に巻き絡ませて、その支持線４の他端側まで送り込むようにする。【選択図】図５
