发明名称 Sling protection pad
摘要 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.

主权项 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 in the cut protection area to bind the inner ply and the outer ply together in the cut protection area, the strengthening stitching being applied in rows systematically across substantially the entire cut protection area to prevent the inner ply from separating from the outer ply and to generate web compression between the outer ply and the inner ply in the cut protection area, causing the inner ply and outer ply in the cut protection area to move as one piece, wherein the combined cutting resistance of the outer ply and the inner ply in the cut protection area is increased, each row of the strengthening stitching is applied within ½ inch of each adjacent row of the strengthening stitching; a second outer ply 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; wherein as the lifting member is engaged, the lifting member protection pad is moved against and generally conforms to the edge of the load.
