Abstract
A wire rope sling made of wire rope having a core and multiple strands of wire helically laid around the core and cut from a predetermined length. Approximately half of the strands of wire are separated from the core and the remaining strands of wire, shifted, relative to the core, a predetermined distance and rewoven with the core and remaining strands of wire into a continuous loop. A splicing sleeve surrounds first and second ends of the approximately half of the strands and a continuous section of the core and remaining strands in a tightly engaged manner and another splicing sleeve surrounds first and second ends of the core and the remaining strands and a continuous section of the approximately half of the strands in a tightly engaged manner.

A wire rope sling made of wire rope having a core and multiple strands of wire helically laid around said core and cut from a predetermined length providing first and second ends, approximately half of said strands of wire having been separated from said core and remaining strands of wire, shifted relative to said core and remaining strands of wire a predetermined distance and rewoven with said core and remaining strands of wire into a continuous loop, the first and second ends of said approximately half of said strands meeting along a continuous section of said core and remaining strands, the first and second ends of said core and remaining strands meeting along a continuous section of said approximately half of said strands;
- a first splicing sleeve surrounding said first and second ends of said approximately half of said strands and said continuous section of said core and remaining strands in tight engagement therewith and a second splicing sleeve surrounding said first and second ends of said core and remaining strands and said continuous section of said approximately half of said strands in tight engagement therewith.
A wire rope sling made of wire rope having a core and six strands of wire helically laid around said core and cut from a predetermined length providing first and second ends of said core and wire strands, three of said strands having been separated from said core and the other three of said strands, shifted relative to said core and other three strands a predetermined distance and rewoven into a continuous loop, the first and second ends of said three strands meeting along a continuous section of said core and other three strands, the first and second ends of said core and other three strands meeting along a continuous section of said three strands, a first splicing sleeve surrounding said first and second ends of said three strands and said continuous section of said core and other three strands in a tightly engaged manner and a second splicing sleeve surrounding said first and second ends of said core and three other strands and said continuous section of three strands in a tightly engaged manner.
A method of making a wire rope sling from a wire rope having a core and six or more strands of wire helically laid around said core comprising the steps of:
- cutting a predetermined length of rope to provide first and second ends of said core and wire strands;
- separating three or more of said strands from said core and other strands;
- shifting said three or more strands along side said core and other strands, a predetermined amount;
- reweaving said three or more strands with said core and other strands to create a rope of three portions, a midportion which comprises said three or more strands rewoven with said core and other strands, an end portion of said three or more strands and another end portion of said core and other strands;
- bringing said end portions together by reweaving said three or more strands with said core and other strands to form a continuous loop, the first and second ends of said three or more strands meeting along a continuous section of said core and other strands, the first and second ends of said core and other strands meeting along a continuous section of said three or more strands;
- surrounding said first and second ends of said three or more strands and said continuous section of said core and other strands with a first tubular splicing member;
- surrounding said first and second ends of said core and other strands and said continuous section of said three or more strands with a second tubular splicing member;
- and
- forcing said first and second splicing members and the wire strands surrounded thereby into fixed engagement.
