Abstract

The invention is related to a roundsling in the form of an endless loop consisting of a core containing at least two turns of a load-bearing strand material comprising fibres with a tenacity of at least 10 cN/dTex and a protective covering around said core, wherein the strand material is in the form of a braided or laid rope, the terminal ends of which are connected with a splice. The invention further relates to a method for constructing a roundsling comprising a step of winding a braided or laid rope on two reels such that part of the turns is on the reels and another part is between the reels wherein the part between the reels is supported, and a step of making a splice in the two terminal ends of the rope.

Claims (10)

1. Roundsling consisting of a load-bearing core containing at least two turns of a load-bearing strand material comprising fibres with a tenacity of at least 10 cN/dTex and a protective covering around said core, wherein the strand material is a braided or laid rope, the terminal ends of which are connected with a splice.

2. Roundsling according to claim 1 , wherein the load-bearing core contains between 2 and 7 turns of rope.

3. Roundsling according to claim 1 , wherein the fibres are high modulus polyethylene fibres.

4. Roundsling according to claim 1 , wherein the turns are all parallel and of substantially equal length.

5. Roundsling according to claim 1 , wherein the splice is either over or under all turns of rope.

6. Method for constructing a roundsling according to claim 1 , comprising a step of winding a braided or laid rope on two reels, thus forming parallel turns, such that part of the turns is on the reels and another part is between the reels, wherein the part between the reels is supported, and a step of making a splice in the two terminal ends of the rope.

7. Method according to claim 6 , wherein the splice is made over or under all parallel turns of the rope between the reels.

8. Roundsling according to claim 1 , wherein the strand material is a braided rope comprising at least 12 strands.

9. Roundsling according to claim 1 , wherein the strand material is a laid rope with a tucked splice.

10. Roundsling according to claim 1 , wherein the turns of rope are all parallel and of substantially equal length.
