Buy SHACKLES that aren't shit

Not to bash on Trail Gear, but holy shit check out the differences in these shackles.
Trail Gear 3/4" Shackle WLL = 4.75T____5:1 Design Factor (this is the design factor for most US shackles)
CM 3/4" Super Carbon Shackle WLL = 6.5T_____6:1 Design Factor

That is over a 15 Ton difference in breaking strength.

Awesome, thanks

 

Yup

 

4.75T is pretty standard for a 3/4” pin shackle.

 

Nice plate!

 

6 1/2 Ton rated USA 3/4 shackles are all we recommend. Worth the extra few $$. Not worth risking failure when you need it and potential injury to yourself or bystanders.
Plus

 

Yes. And why not upgrade above "standard"?

 

No reason not to. Just you mentioned something about bashing Trail Gear. Even nice Crosby 3/4” shackles used by rigging crews are rated at 4.75T

 

I mentioned not bashing trail gear. And their shackle is a China shackle too, something I'm trying to avoid.

 

Yea. I was just pointing out their rating is typical of well respected brands, including Crosby. The biggest issue will be if you use the shackle with a snatch block. At about 20k, the 4-1/2T shackles will start to yield. The Chinese made ones will probably yield much lower than that. I’ve seen tests where the Chinese made ones were yielding around 12k, while the US made ones were closer to 21k.

 

Yup, having maxed out an 8000 pound winch and using a snatch block this weekend, that's a big deal for me.

Here's a pic of the 4runner we had to use the snatch block on and even then barely moved.

 

yeah but your thread title pretty clearly calls them "shit", lol.

Not saying I disagree, just found it funny. Given the choice I would 100% spend the extra few bucks on something that may be overkill for my needs, but I won't ever have to worry about failing. Especially when risk of injury is involved.

 

Trail Gear is, in fact, shit.

 

Going to have to double check that now but I swear our Crosbys at work are more than 4.75T WLL

That said we may have Chicago shackles and not Crosby.

Hrmm...

 

Seems to me that the Feds require a factor of safety of 4 over the labeled rating. That could mean a 4.75T shackle would physically open at 19T across the pin and hoop. That is more than the point where yielding takes place and ruins the shackle - it is the ultimate strength of the device. So the higher rated shackle could comply with the regulation and open at 26T but may or may not have an advantage in yield strength. The assumption is that the user will try to avoid a loading over the labeled rating - which should keep them away from the yield point.

 

Good point. One of the problems is during a hard recovery I don't always inspect my gear between each pull. Maybe during a jerking pull I started to yield the shackle into plastic deformation.

Also, do you know if the "feds" have any control over the China shackles?

 

The standard is here is anyone is interested: https://www.landmannwire.com/wp-content/uploads/2013/01/RR-C-271F.pdf

The part relating to shackles starts on page 15.

 

While I was working at a mine (Peabody Coal), we got a visit from MSHA (mine safety and health admin) inspector and he brought along a fellow from the Department of Commerce. They went through the warehouse bins looking for bolts and fasteners with specific manufacturers marks - known to be counterfeited by Korea. The identified material had to be removed from the bins and certified as destroyed by a licensed engineer.

 

i posted a video in this section not long ago. thread title is "soft vs hard shackles"

pretty good info

 

Didn’t see this thread prior to getting a set of cheap Chinese shackles, since then I’ve replaced them with a Crosby set. My buddy told me when it comes to safety while rigging and recovery don’t take a chance.
