【発明の効果】
以上のように本発明のワイヤロープ接続方法によれば、複数の第１ストランドのうちの一部を残して第１ワイヤロープの端から所定長さだけ第１ストランドを切断する工程と、複数の第２ストランドのうちの一部を残して第２ワイヤロープの端から所定長さだけ第２ストランドを切断する工程と、残った第１ストランドと残った第２ストランドとを沿わせて重ねる工程と、第１ストランドおよび第２ストランドの端で、重ねられた第１ストランドおよび第２ストランド上に金属スリーブを被せる工程と、上記金属スリーブを円筒面を有するダイスにより圧着して、第１および第２ストランドとの間に形成される空間内に上記金属スリーブを圧入充填させて、第１および第２ワイヤロープを互いに締結する工程とを備えているので、ロープ接続部を容易に形成でき、得られたロープ接続部は外径が小さく、充分な引っ張り強度を持ち、ロープ端部の変形も生じることがない。[0025]
【Effect of the invention】
As described above, according to the wire rope connection method of the present invention, a step of cutting the first strand by a predetermined length from the end of the first wire rope while leaving a part of the plurality of first strands, and a plurality of steps Cutting the second strand by a predetermined length from the end of the second wire rope leaving a part of the second strand, and stacking the remaining first strand and the remaining second strand along a line Covering a metal sleeve on the overlapped first and second strands at the ends of the first and second strands, and pressing the metal sleeve with a die having a cylindrical surface to form the first and second in the space formed between the strands by press-filling the metal sleeve, since the first and second wire rope and a step of fastening together, rope connection The can be easily formed, rope connection portions obtained outer diameter is small and has sufficient tensile strength, do not occur deformation of the rope ends.
