    Abstract: A sling for industrial lifting made of a load-bearing core and a cover. The cover protects the plurality of yarns that make-up the core. Each core yarn is made of a number of core threads twisted together. The core yarns are twisted together where the twist is in the same direction as the individual core strands and a different direction than the twist of the cover. The present invention describes the method of twisting the core yarns together by inserting core yarns substantially parallel into a cover that has a twist opposite of each core strand. As the core strands are inserted into the cover, the twists of the individual core yarns interact with the twist of the cove, resulting in the core yarns twisting together.

    Abstract: In one aspect, the present disclosure relates to a high-strength prestressing strand having a seven-wire structure in which one core wire and six outer wires are stranded. An external diameter of the strand is from 15.0 mm to 16.1 mm, a total cross-sectional area of the strand is 135 mm2 or more, and a load at 0.2% permanent elongation is 266 kN or more. A relaxation value measured after a 1000-hour relaxation test is 2.5% or lower and a diameter of the core wire is 5.35±0.3 mm and a diameter of the outer wires is 5.15±0.25 mm. The core wire and the outer wires each have a composition of at least 0.90% carbon. The prestressing strand is manufactured by stranding the core wire and outer wires, giving a stretching treatment, and giving a bluing treatment at a temperature of 380° C. or more and 430° C. or less after or at the same time with the stretching treatment.
