Abstract

A flexible lifting member protection pad includes a cut protection area with strengthening stitching which cooperates with an inner ply and an outer ply to bind the inner ply and the outer ply together in the cut protection area, such that the inner ply, outer ply and strengthening stitching act and move as one piece to increase the combined cutting resistance of the cut protection area. The strengthening stitching is distributed or applied systematically across substantially the entire cut protection area. This configuration allows compression to be generated across the inner ply of the cut protection area when the protection pad is moved against the edge of the load, whereby the inner ply of the cut protection area resists being cut by the edge of the load.

Claims

1. A flexible lifting member protection pad for insertion between an edge of a load to be lifted and a lifting member, the lifting member protection pad comprising:

an outer ply;

an inner ply;

a cut protection area, the cut protection area having strengthening stitching which cooperates with the inner ply and the outer ply to bind the inner ply and the outer ply together in the cut protection area, the strengthening stitching being applied systematically across substantially the entire cut protection area;

wherein as the lifting member is engaged, the lifting member protection pad is moved against and generally conforms to the edge of the load, generating compression across the inner ply of the cut protection area, such that the inner ply of the cut protection area resists being cut by the edge of the load.

2. The flexible lifting member protection pad as recited in claim 1, wherein a second outer ply is attached to the outer ply, the second outer ply having essentially the same dimensions as the outer ply, the outer ply and the second outer ply include perimeter stitching.

3. The flexible lifting member protection pad as recited in claim 1, wherein the inner ply has smaller dimensions than the outer ply.

4. The flexible lifting member protection pad as recited in claim 1, wherein the strengthening stitching is Kevlar thread.

5. The flexible lifting member protection pad as recited in claim 1, wherein the strengthening stitching is applied in a zigzag pattern which extends across substantially the entire width of the inner ply to form the cut protection area.

6. The flexible lifting member protection pad as recited in claim 1, wherein the strengthening stitching is applied in a parallel or substantially parallel pattern which extends across substantially the entire width of the inner ply to form the cut protection area.

7. The flexible lifting member protection pad as recited in claim 1, wherein each row of the systematically applied strengthening stitching is applied within ¾

inch of each adjacent row of the systematically applied strengthening stitching, wherein the application of the strengthening stitching across the entire cut protection area prevents the inner ply from separating from the outer ply, causing the inner ply, the outer ply and strengthening stitching to move as one piece increasing the cutting resistance of the cut protection area.

8. The flexible lifting member protection pad as recited in claim 1, wherein each row of the systematically applied strengthening stitching is applied in within ½

inch of each adjacent row of the systematically applied strengthening stitching, wherein the application of the strengthening stitching across the entire cut protection area prevents the inner ply from separating from the outer ply, causing the inner ply, the outer ply and strengthening stitching to move as one piece increasing the cutting resistance of the cut protection area.

9. The flexible lifting member protection pad as recited in claim 1, wherein securing members are provided proximate the cut protection area are used to attach the flexible lifting member protection pad to the lifting member.

10. The flexible lifting member protection pad as recited in claim 9, wherein the securing members extend between the inner ply and the outer ply and are secured therein by strengthening stitching.

11. A sling protection pad for insertion between an edge of a load to be lifted and a sling, the sling protection pad comprising:

at least one outer ply;

at least one inner ply;

strengthening stitching applied to a portion of the at least one outer ply and the at least one inner ply to form a cut protection area, the strengthening stitching binds the inner ply to the outer ply in the cut protection area, the strengthening stitching being applied systematically across the entire cut protection area;

wherein as the sling protection pad is moved against the edge of the load, the ate least one inner ply of the cut protection area is compressed, such that the at least one inner ply of the cut protection area resists being cut by the edge of the load.

12. The sling protection pad as recited in claim 11, wherein the at least one outer ply is two outer plies, the two outer plies having essentially the same dimensions.

13. The sling protection pad as recited in claim 12, wherein the inner ply has smaller dimensions than the two outer plies.

14. The sling protection pad as recited in claim 11, wherein each row of the systematically applied strengthening stitching is applied within ¾

inch of each adjacent row of the systematically applied strengthening stitching, wherein the application of the strengthening stitching across the entire cut protection area prevents the at least one inner ply from separating from the at least one outer ply, causing the at least one inner ply, the at least one outer ply and strengthening stitching to move as one piece increasing the cutting resistance of the cut protection area.

15. The sling protection pad as recited in claim 11, wherein securing members are provided proximate the cut protection area are used to attach the sling protection pad to the sling, the securing members cooperate with the at least one inner ply and the at least one outer ply to prevent the sling from engaging the load.

16. A flexible lifting member protection pad for insertion between an edge of a load to be lifted and a lifting member, the lifting member protection pad comprising:

a cut protection area, the cut protection area having multiple plies of webbing bonded together using strengthening stitching applied through the multiple plies, the strengthening stitching is distributed over the entire cut protection area, the cooperation of the strengthening stitching and the multiple plies of webbing cooperate to generate compression across an inner ply of the multiple plies of the cut protection area, such that the inner ply of the cut protection area resists being cut by the edge of the load as the inner ply engages the ends of the load.

17. The flexible lifting member protection pad as recited in claim 16, wherein the strengthening stitching is Kevlar thread.

18. The flexible lifting member protection pad as recited in claim 16, wherein each row of the applied strengthening stitching is applied within ¾

inch of each adjacent row of the applied strengthening stitching, wherein the application of the strengthening stitching across the entire cut protection area prevents the inner ply from separating from the outer ply, causing the multiple plies and strengthening stitching to move as one piece increasing the cutting resistance of the cut protection area.

19. The flexible lifting member protection pad as recited in claim 16, wherein securing members provided proximate the cut protection area are used to attach the flexible lifting member protection pad to the lifting member, the securing members cooperate with the multiple plies o prevent the sling from engaging the load.

20. The flexible lifting member protection pad as recited in claim 16, wherein the inner ply has smaller dimensions than the outer ply.
