PROBLEM TO BE SOLVED: To provide a wire rope sling, which enables a neck part of an eye to be well fastened, a thimble to easily be installed, and backlash of the installed thimble to be suppressed, and a manufacturing method thereof.SOLUTION: A flemish process in a wire rope sling manufacturing method comprises splitting an end of a rope R into a first strand group S1 and a second strand group S2, and combining these two strands each other from opposite direction to form an eye 10. A first splicing margin 11A and a second splicing margin 11B are formed by leaving the first strand group S1 and the second strand group S2 near a neck part 11 of the eye 10 uncombined for at least half of the eye circumference during the flemish process. A first terminal strand SE1 and a second terminal strand SE2 are formed by untwisting the first strand group S1 and the second strand group S2 from the end to the neck part 11 of the eye 10. Then a neck fastening process, in which at least a piece of strand of the first terminal strand SE1 and a piece of strand of the second terminal strand SE2 are respectively passed between a strand S comprising the first splicing margin 11A and the second splicing margin 11B, is performed.
【課題】アイの首部の締り状態が良く、シンブルの取り付けが容易で、取り付けられた前記シンブルのガタつきを抑制する玉掛索、及び、その製造方法の提供。【解決手段】ロープRの端部を構成する第一ストランド群S1と第二ストランド群S2とに二分し、互いに反対方向から組み合わせてアイ10を形成するフレミッシュ工程時に、前記アイ10の首部11近辺における第一ストランド群S1と第二ストランド群S2との組み合わせを少なくとも半巻分残すことによって第一差し代部11Aと第二差し代部11Bを形成し、更に、前記第一ストランド群S1と前記第二ストランド群S2の撚りを末端から前記アイ10の首部11まで解くことによって形成された第一端末ストランドSE1及び第二端末ストランドSE2の内の少なくとも各一本ずつを、それぞれ、第一差し代部11Aと第二差し代部11Bを構成するストランドS間に差し通す首詰め工程を実行する。【選択図】図1
