Protective cover for slings, ropes, cables and the like
A protective cover formed substantially of ultra high molecular weight polyethylene yarns and having first and second opposing edges connected by a high shear strength hook and loop fastener system. The high shear strength hook and loop fastener system includes areas of a plurality of high shear strength hooks along opposing edges of the cover and an intermediate disposable strip having a plurality of loops on both sides of the strip configured to be received between the areas having the plurality of hooks. The cover wraps around the sling so that a portion of the first edge and second edge overlap with the intermediate disposable strip to form the releasable connection. When the edges are released, the intermediate strip may be replaced, when worn, by a new intermediate strip with the remainder of the cover and fastener system being reusable.
1. A protective cover for a rope, cable, or sling comprising:
a fabric sheet formed substantially of ultra high molecular weight polyethylene yarns and having first and second opposing edges;
a high shear strength, renewable and releasable hook and loop fastener system releasably connecting the first and second opposing edges and comprising
a) areas containing a plurality of mushroom-shaped hooks extending along the first and second opposing edges;
b) an intermediate disposable strip having a plurality of loops on each side thereof and so configured as to receive the areas having the plurality of hooks; and
whereby when the cover is wrapped around the rope, cable, or sling so that a portion of the first edge and second edge overlap with the intermediate disposable strip, and the edges are pressed against the intermediate disposable strip, the high shear strength, releasable connection is formed.
2. The cover of claim 1 , wherein the plurality of hooks are mushroom-shaped.
3. The cover of claim 1 wherein the hook and loop fastener system has a shear strength of at least 36.0 lb/sq. in.
4. The cover of claim 1 , wherein at least some of the plurality of loops on the disposable strip break when removed from the areas of the plurality of hooks.
5. The cover of claim 1 , wherein the fabric sheet comprises
a first area of plurality of hooks along one edge of a first side of the fabric sheet, and
a second area of plurality of hooks along the other edge of a second side of the fabric sheet.
6. The cover of claim 1 , wherein the intermediate disposable strip has shape that mates with the first and second areas of plurality of hooks.
7. The cover of claim 1 , wherein the plurality of loops are selected from the group consisting of woven loops, knitted loops, or nonwoven loops, or combinations thereof.
8. The cover of claim 1 , further comprising at least a second intermediate disposable strip, the second intermediate disposable strip replaces the first intermediate disposable strip upon removal from the connection of hook and loop fasteners.
9. The cover of claim 1 , wherein the fabric sheet further comprises a thermoplastic film bonded to at least one side thereof.
