Working Load Limits - Straps and Shackles
I'm looking to get some basic recovery equipment and am confused by the various strength ratings of the key components: shackles and straps. I have found some fairly inexpensive 3/4" d-shackles with a WLL of 14,000 lbs. I don't know whether to get a 3" wide recovery strap with a tensile strength of 27,000 lbs and a breaking stength of 21,600 lbs or a 2" strap with tensile of 18,000 and breaking of 14,400.
If the old adage "a chain is only as strong as its weakest link" is true and the d-shackle WLL is 14,000 lbs, is there any reason to get the stronger 3" strap? Am I correct in equating the working load limit of the shackle to the tensile or braking strength of the strap?
