    Abstract: PROBLEM TO BE SOLVED: To obtain a high-strength wire rope that has a low Yoriberi value (value determined by a reduced load at break of wire rope by twisting), is thin and lightweight and has high load at break. SOLUTION: The high-strength wire rope is obtained by subjecting a high carbon steel wire rod obtained by adding 0.1-0.3 wt.% of chromium to hyper-eutictoid steel having 1.01-1.20 wt.% carbon content to lead patenting to make the high carbon steel wire rod having 1,450-1,600N/mm 2 tensile strength and 20-40% drawing value of the reduction of area, carrying out a die wire drawing process at ≤150°C wire temperature at the exit of a die box, reducing the diameter, winding the wire on the correction roller and using wire having 2,350-3,000N/mm 2 tensile strength and 20-50 times twisting value as a strand.
