After explaining what I would use the strap for the sales guy called out an engineer. He explained to me that all the strap that they manufacture have a Vertical working load rating. Meaning that if a strap is rated to 10k it's break strenght is actually 6 time that at 60k. Not your typical ratings for tow straps that usually only 1/3 of break strength. So he said that for recovery I can actually select a strap with a lower rating than what I would need because the break strengths are so high. He pointed out that they have a 4 inch strap rated to 11,500 pounds, however the break strength is 69k pounds. He said that in my application he would safely say I could recover a vehicle weighting 30k pounds with that strap and not worry about a failure. He also told me that the ratings and break strength they label the straps with are just the numbers they release to the public. He said their actual test show much higher tolerances. I guess they like to over engineer and CYA.
After everything was said and done, they are going to make me a custom 4 inch by 30 foot two ply recovery strap. It's not cheap, but at this point I am getting exactly what I want. Everything from the color, type of loop, stitching, protective codura coverings. You name it, I can get it.
Just one more thing. In case you wondering about this company. They manufature the slings and straps used to get the Space Shutle on and off it's 747 and mated to the rocket boosters in the VAB. So if this company is good enough for NASA and the Space shuttle, it's good enough for me.
