How Strong are Twisted Ratchet Straps?

I'm testing the myth that a twisted ratchet strap loses 50 percent of its load capacity by putting a twist in it. So I build a test rig to find out the truth. I test everything from 1 twist to 10 twists. I even test knots and water soaked straps. Exploding them produced some pretty shocking results!

      Just wanted to add this method of mine to this pinned comment; Just use the tail end of the strap and tie it around the tensioned straps to help prevent them from vibrating in the wind. That is if you have enough length left after fastening down your loads. I might even make a video for everyone to see how I do it.

    The one with no twist, 1 twist, and 4 twists could have easily been strength variation from manufacturing. It would be a good idea to test several straps at each level and then take the average.

    I'm really surprised at this test. I use a lot of ratchet straps, and always thought the weak point would be the metal bar that engages the ratchet wheel. Not a single failure was there, that part is obviously stronger than I thought. I use the 1 inch straps up to the 4 inch trucker tie downs, and never twist them. I mostly tie down cars and motorcycles and never over load them. I now have greater faith in these straps. This was very interesting, thanks for the post and keep up the good work.

    The twist crease makes me wonder if it'll reduce the life of your straps faster, though if it's vibrating less it would probably even out with the flat star's wear.

    The concerning part is that where the twist was it was getting hot, and it looked like it started melting. This might reduce the longevity of a twisted strap, and reduce its strength over repeated use. Worst case this heating might weaken it during load which could cause it to break at a very inopportune time.

    The twisting or knotting takes the ability of the rope to stretch away, it's already under tension at that point.

    I'd like to see an average over ten straps for each of the test modes. I'd also like to see the difference between one, two, three, four, and five twists at the length you were using. Some modelling in MathCad predicts twisted straps are more durable until any part of the strap touches another part of the strap. At the point they touch they create a weakened spot. That is consistent with your testing. Underload, the weakest part is where the strap touches itself. I suspect at the length you tested the strap will be strongest with three twists. Subsequently shorter lengths would reduce the number of twists to two, then one, then none. Longer lengths would be strongest will more twists up to a point where the spool contact is the weakest part. Ghostbusters was right - never cross the streams!

    well facts put hot air to rest . as a crane operator . a strap rating with a straight lift is the full rate listed . a cradle or basket lift doubles the capacity. when the strap is used as a" choke " one end is put through a loop and and a strap encircles the lift , that is the weakest configuration good job and that cost some bucks to make that video .

    Good experiment and demonstration, in addition, there can be variations of material that can give slightly higher or lower results from the 10000 Ib breaking strength, hence 3330 Ib working rating will give the margin of safety. The wet condition give a low result is interesting.

    • sixfootbear

      5 uur geleden

      Does it? I pull as much slack as I can through the slot in the barrel then increase the load on the strap by tightening the ratchet as much as I can.If too much strap comes through that tightening I release the ratchet and start again. After a short time driving I stop and check all the straps tightening where,and if, needed. My boss calls me a perfectionist.I disagree with him.

From hauling metal, decking and sheetrock, to shingles and commercial roofing products; those ratchets do what they're made to do. I agree with your assessment of the single twist reducing the flap and noise from a flat strap. I don't ever leave the yard without checking my straps are tight and twisted. Kudos!

    You're generating heat at the ratchet strap (and even more at the knot). That's creating a weak point. Do this again but with a constant flow of cold water on the ratchet and you should see an improvement.

    Yeah uh so coming from a trucker we put only a half twist in each strap on each side of the trailer for two reasons. 1. Deflects wind. 2. Allows strap to become more rigid and maintain its level of "tightness" Twists dont add strength. Even Swift drivers know that shit.

  93. phoenix21studios

    1. this wasn't scientific at all, you have to do multiple tests on each set ups to get an average. 2. the twists are not "bites" (bends in the rope that change its direction) but if you notice where the strap DOES break, its near the bite which is where it is reduced by 50%.

    So i may be late, but I'll ask anyway. If one twist added strength over control, but a wet straight strap slightly lost strength under control, is it safe to say that a twisted wet strap would be as strong or slighlty under the strength of a dry straight strap (control) but have less strength than a dry twist or would things be inverse because of the moisture/wetness?

    The test I think you could add would be to take the strap to 3000kg and then let it cool. Then take it higher. As you've noted the failure appears to have some relation to heat. I'd imagine when they test these in a lab they will do a shock test but they'll also do a test over a longer period. It goes without saying it is never wise to operate a strap or load device anywhere near the safe working load
