When I pulled a skateboard, I only put a twist in the straps on insulation loads or other loads that you could not put much torque in during securement. Without the twist, the straps got so loose on those loads, quickly. I imagine every flatbedder has their own methods that works for them but one thing is universal: load check!!!

Way back on the day when I was in the parasailing biz I used a 5/16 Spectra line that is 40% stronger than kevalar with a Wll of 9800 lbs.
Every once in a great while the bearing that the line feed ran through would seize . Running that line through there on that frozen roller with any tension on it and you may as well throw the line out even though it appears undamaged.
Slightest bit of heat killed it. Also you had to constantly trim back the part that was exposed to the Florida sunlight .
After 6 months I would buy another $1500 bolt of it as the UVs would break it down.
I would be more worried about UV degradation than hard spots from twists. -
I do twist just about all my straps and I do put at least 8 straps on 48,000 lbs.

In other words, the pressure on indirect securement is spread out across the securement device, if that makes sense. I'm probably wrong though lol.cke and God prefers Diesels Thank this. -
To visualize this, picture a 100 pound weight hanging from a chain, the load on the chain is obviously 100 pounds. Now picture running that chain through a pulley, so that you have to pull down on the chain to lift that hundred pounds. You now have the hundred pounds of the weight on one side, and on the other side the hundred pounds of force of you pulling on the chain to hold the weight up. So you have a total of 200 pounds downward Force rather than just 100 pounds. The first example is direct, and the second example is the indirect.
It's rather counterintuitive, because the tension in the chain does not changeLast edited: May 8, 2021
