He spelled absurd wrong.

We'll let him slide on that one. I've been known to make a spelling or grammar error now and then, and I pride myself on being above average in spelling and grammar precision. Heck, if I read an old post of mine with an error in it, I'll edit it even years after the fact because it drives me crazy to make those mistakes...

I do the same for all the same reasons. The worst is when I don't catch it in time and it winds up in a quote.

That said, even though the ball point pen gives some idea of scale, it doesn't tell the whole story. I am out of the 3/16" stuff but I had the next size up so I made one out of that. Next to a normal soft shackle gives you an idea that it will be very difficult to tear up our normal sized soft shackle without the winch line breaking first.

Completely spaced that you had the Wizard line. Ordered a few soft shackles for the LJ to help make up for the time you wasted with me today .

Before I send them out, you know I depend on common sense and understanding from my customers, right? I use them as a utility item, they are disposable wear items that are meant to protect the important bits and they are economical enough (I hope) that you can abuse them and toss them when you don't like how they look. If you ordered a fashion accessory color, just know I'll swap it out for bright green so you don't lose them.

edit- you know you ordered 4 shackles, right?

Ha, yes and yes.

Red is acceptable but you would really like the green ones.

That's fine, as long as it's visible and not named after a vegetable.

You are in luck. Nuclear Neon Lime Green is a fruit.

Yup, also strikes me odd that they want f'in $70 for it.

I don't think we got the WLL thing worked out well enough to understand what I pick on and why. It has to do with the mixing and matching of industry rules and practices and that shackle is a clear illustration of why I pick on that so much.

If we apply the same rules they used on the shackle to the common 9500 lb rated winch, you will only be able to use it to make a 2000 lb pull. We'll overlook for a bit that most of our winch pulls are on the top two layers so not much more than double that anyway.

Point that I think most overlook is once you start applying a WLL, you have to use it for everything and whatever rule you applied, also has to be applied to each item you sell.

I also can't find the logic behind applying a 5-1 safety factor to something that isn't used in overhead rigging. Not to mention, there is a lot of overhead stuff with a 4-1 safety factor that is just fine. Why not 4-1 and at least get it so it is able to be used with our 9500 lbs rated winches?

The reality is those tags and numbers are generally for the number collectors and nary a smidgen of thought will be given to their use in real life once we've shown all our buddies that we collected some numbers. No one will NOT use that shackle on a recovery where a 9500 lbs winch is in use, I know it, they know it, and Warn knows it.

I assume the reason for the WLL requirements for overhead lifting is the potential consequences of a failure, when compared to what we do. Is that a correct assumption?

Yes, the overhead crane and rigging industry has very strict rules with minimum safety factors typically in the 4-1 or 5-1 range with very strict methods the manufacturers have to follow to be in compliance. IIRC, the safety factor is based on proof load and not maximum breaking strength. I can look it up again if it matters.

Point being again, if you put out a shackle with a WLL based on a 5-1 safety factor, then the same rules prohibit you from shipping a 9500 lbs rated winch with a 5/16" steel cable that breaks at 9800 lbs. You either have to install a clutch that limits pulling power to 1/5 or 1/4 of the line's breaking strength, or install a line with 4-5 times the rated pulling power or something along the lines of max breaking strength of 38,000 lbs for the line.

If you as a company understand the absurdity of either of those options, then you tag the shackle with a rated line use. USE with no more than our 3/8" Spydura line and since that line is roughly in the 18-20,000 lb break strength range, it automatically has a near double safety factor.

Actually ran across that yesterday on a Crosby sheet.

MBS/5 = WLL Then each one gets proof tested to 2.5xWLL:

The best part of the Crosby site, used a lot of their stuff over the years.

Yum I wonder if that fancy sand hollow hotel has a boil

That's not the recipe I use. It used to be linked at the header of the Crosby site. Now you just have to search it and it still comes up.

They used to put on a big boil in Houston for OTC (Offshore Technology Conference)
