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.

  • One test you didn’t do !!!!! Try multi use strap we don’t just use the strap once and buy a new one we usually use it over 10 years ? Thanks

  • The twist can control vibrational forces while being transported so is important.Im sure there is engineering on all this somewhere.

  • This all depends on how the stresses are distributed and concentrated especially at the knot which introduces eccentric forces along with tension and bearing forces.

  • maybe the strap is defective at the same location...…. if the test is done with a shorter length or longer for the strap, the result and the break of the strap may be different.

  • Fantastic experiment. For me, the take-away is that the limiting component is the ratchet itself, which creates a stress concentration in the strap. One ratchet may have very different performance to another - but a twist in the strap is not worth worrying about.

  • You should add some engine oil and a little fresh grease and some old dirty grease, all the truckers I know after the first use that’s the condition of those straps some even have hydraulic fluid along with the oil and grease! That being nylon petroleum products do affect the fibers strength! Just as gasoline or diesel!

  • Hello. OK, this good not to encourage myth. Interesting tests would be : 1) How to sew straps together if you want longer ones? Or if you want to sew them to something, a heavy capacity bag for instance 2) Test "good-looking" sections of broken straps (far from broken part) that people would like to re-use for economy... Can not broken straps be authorized for re-use ? Because heavy load bags are marked "do not re-use, destroy after use".

  • I'd guess that the twists reducing road noise also reduce stress on the strap during travel. Humming suggests resonant frequencies, implying more stress than you'd expect simply from wind velocity alone.

  • So, what I’m seeing is that 1 or 2 twist won’t really make a notable difference to the strength but don’t go over that and make sure to never leave a knot in the strap

  • You should make a strap that eliminates the ratchet. Similar to a tow strap. And test the break point of that (since it kept breaking at the spool)

  • My dad hauled flatbed for years, ONE twist in a strap keeps them from vibrating going down the road, vibration causes the straps individual strings to break.

  • Mechanical resonance can produce vibrations strong enough to destroy the object in which they occur. SO putting one twist in a strap may actually increase its strength when traveling . I have had straps vibrate till they broke, so now I always put a twist in my straps. I would like someone to test and show how vibration resonance can destroy a strap.

  • great stuff, obviously. but... i wonder how much variability there is in a given bunch of straps? just for the fun of it, it would be interesting to repeat one or two of the tests, say zero and a couple of twists and maybe the wet strap, 3 times. i think it’s (slightly) better methodology.

  • In my wildest stretches of imagination in the early nineties when the "world wide web" was in its infancy, I never envisioned a video of a guy testing burst strength on ratchet straps. Fireball, you are amazing! Thanks for this entertaining AND instructive video. Nothing like the scientific approach to silence those who criticize or doubt without the data. Gotta love the Internets!

  • The results of no twist, one, four, ten and wet strap are pure example of measurement error. Your measurement equipment probably have no less than 2% measurement error. Compare results. Except 10 twists all of those measurements are into +- 2% error

  • I used to get crap from a few friends when I strapped my kayak to the top of my van. I would put a couple twists in it to stop the vibrations. My know it all friends said my straps would break. I think they were overestimating the stresses a streamlined kayak was putting on the straps.

  • Great experiment! But this test is only useful for "static loads", I would like to know how much each different sample stretched, because it looks like the more twists in the strap the less it stretched. Obviously the more the strap can stretch, the more "tough" the strap will be and more resistant to instantaneous loads, for example hitting a pothole or sudden stop would cause a large instantaneous load on the strap and a more stretchy strap would be able to "dampen" the impact, therefore making it effectively "stronger".

  • Interesting video, next you could try to repair and reuse those straps to see how well they hold up. Option's I can think of: 1. just re-use the longer end. cut off the tear and reconnect the hook and ratchet. 2. some sort of super strength glue 3. knot the ends together 🤣 4. sew the ends together with some good overlap. Not sure if there are special stitch patterns that would help. 5. melt the ends together? 6. weave the ends together. This one might be a huge pain / impossible. I know for sail-plane flying you can re-weave the ends of the winch rope if not using steel cables. However that is for much lower loads and they tend to slip apart when wet. 7. combine methods? melt and sew? glue and sew? I expect they will all fail much sooner than the new straps but it might be interesting how much worse they perform.
