Well done guys! I've been off-roading for 26 years and this was very useful information to know. Before seeing this I would have thought that there might be on occasions a need for hitting speeds of maybe 10 mph at least. I now see that going over probably 6 mph will never be needed. Luckily my rope is also 1 ⅛" thick too. I never foresee using it to pull out more than a 1 ton truck.
Kinetic rope is the best! I'm using Miolle brand kinetic rope, worked like a charm. Nice hi-vis color makes it easy to see and, more importantly, stay clear of during the snatch. Seems very well made and robust. I definitely recommend this kinetic rope. Worth my money 👌👌👌
Regardless though, now that we have a metaphorical measuring stick, with a heavier truck, just start at a lower speed. Most heavier trucks have larger engines with more torque so if someone follows his instructions, and initially just tries a straight traction pull, most 3/4 and 1 ton trucks have the weight (traction) and torque to just straight pull the vehicle out without needing momentum.
Great data ... and good advice ... thanks for running this test and reporting the results. What diameter and length of rope did you use? I'm guessing 7/8" diameter and 30 foot length. Would love to see the difference in load created by a different length of kinetic rope ... suspect that a shorter rope will create less load at each speed. If so, then the 20 foot ropes could safely use a little more speed than 5mph. Most of us are recovering with Jeeps, but it would be interesting to see what loads a heavier vehicle could produce ... that would be a difficult data point to obtain because of speed control.
Excellent video. But let me hop on my soapbox for a second. For anyone looking at a recovery strap, make sure it is made of NYLON if you are doing a dynamic recovery. I've seen too many people with straps that are advertised as "recovery" straps, but are made of Poly/Silk, or poly, or polyester. The thing to remember is the ONLY material appropriate for a dynamic recovery is nylon. Anything else doesn't have enough stretch and will give much higher shock loads. I'd love to see you repeat this video with a polyester strap and show how much higher the loads are.

Great advice. Start slow, and keep everyone away from the blight of the line of pull.
Seriously interesting. Well done for not just hating and showing nicely.
Loving this educational video. Hope you will do more of these. That was a real eye opener and a learning experience. Thanks John and Jaime
I can confirm all the info they provided
And second their opinions
Thank you
Great Video and information. Love to meet up and do more testing with you.
Awesome video, guys! Love the data! May have missed it, but what diameter of rope were you using?
Those load numbers have to get crazy with a heavier truck, even at those speeds

Kinetic energy should increase to the square of the speed (quadratically, not exponentially) so your linear plot looks great!
Absolutely, The numbers were very linear so are it’s make them very predictable at any speed. Thanks 😊

I used a 7/8 rope in this test. Thanks for the kind words.

Quite right!
Thank you.
What was the weight of the loaded Gladiator used?
Be nice to see a regular strap with the same parameters, does the shock load deliver higher peak force....
Good idea.
Great data set boys! Well done.
