Abstract

A rope includes a main rope segment, a branching position and an end connector segment, wherein the end connector segment includes a first rope-branch, which includes a first rope-branch-eye, and a second rope-branch, which includes a second rope-branch-eye, wherein an attainable maximum first effective length of the first rope-branch is higher than 120% of an attainable maximum second effective length of the second rope-branch. The rope allows for alternative favourable manners of connecting the rope to other ropes and to other types of external objects.

Claims (19)

1. A rope, wherein the rope along a longitudinal rope direction of the rope towards a longitudinal rope end of the rope successively comprises at least a main rope segment, a branching position and an end connector segment, wherein:

the branching position is a fixed position along the longitudinal rope direction,

the end connector segment is formed by all parts of the rope that, as seen in said longitudinal rope direction, are extending from the branching position up to the longitudinal rope end,

the end connector segment has two, and only two, branches of the rope,

said two branches of the rope are consisting of a first rope-branch and a second rope-branch, which at said branching position are branched off from the main rope segment,

the first rope-branch comprises a first rope-branch-eye and the second rope-branch comprises a second rope-branch-eye, and

an attainable maximum first effective length of the first rope-branch is higher than 120% of an attainable maximum second effective length of the second rope-branch.

2. The rope according to claim 1 , wherein:

the rope comprises a first plurality of strands, a second plurality of strands, a third plurality of strands and a fourth plurality of strands,

each strand of the first plurality of strands and of the second plurality of strands is continuously extending at least from within the main rope segment to within the first rope-branch,

the first plurality of strands and the second plurality of strands are spliced end-to-end back into each other, thereby at least partially forming said first rope-branch-eye,

each strand of the third plurality of strands and of the fourth plurality of strands is continuously extending at least from within the main rope segment to within the second rope-branch, and

the third plurality of strands and the fourth plurality of strands are spliced end-to-end back into each other, thereby at least partially forming said second rope-branch-eye.

3. The rope according to claim 1 , wherein said attainable maximum first effective length is higher than 150% of said attainable maximum second effective length.

4. A method of using the rope according to claim 1 , wherein a link structure is used to interconnect the first rope-branch-eye and the second rope-branch-eye, so that the first rope-branch, the second rope-branch and said link structure together are forming a rope-eye at said longitudinal rope end of the rope, wherein said rope-eye is suitable for connecting the rope to external objects.

5. The method according to claim 4 , wherein said link structure comprises a link in the form of a shackle of hard and/or soft materials, or wherein said link structure comprises a chain of links.

6. The method according to claim 4 , wherein said link structure comprises a chain of at least two shackles of hard and/or soft materials.

7. The rope according to claim 1 , wherein said attainable maximum first effective length is higher than 200% of said attainable maximum second effective length.

8. The rope according to claim 1 , wherein said attainable maximum first effective length is higher than 300% of said attainable maximum second effective length.
