Choked Biner Rigging

[TreelineNH]

I used an IC big dan on all limbs. When you are doing limbs there is hardly any shock load to the system. When I negative rig I use knots. This is faster anyways since I use rigging rings.

see what I see and feel?

Eww! Looks like the back has been bent inward. Quite hard to understand how that'd happen. Good thing you caught it before it was major issue.

This steele biner has been used very little, it was a gift, it's only 25kn, but I only use if for limbs, nothing big at all, it's never been shock loaded, see what I see and feel? Noticed it after using it today on very small dead Maple limbs, yes I choke them, but I'm pretty consistent about making sure it's not side loaded. I could have missed this from the previous job, but I check them before each use.

Is that spine bent?!
From choking little dead maple limbs?

I have less and less interest in steel biners. Aluminum really seems more abuse resistant, and I couldn't tell you why. It seems counter-intuitive. I just know that I manage to beat up steel biners that I use for rigging within a year to where the gates don't work right or they have visible deformations.
I am still using all of the aluminum biners that I got a couple of years ago for beating up. Buncha rock climbing quick draws and stuff.

I did break the gate on an xsre when i was pulling a dead stick with the throwline. It took my whole body weight bouncing on it for a while, and I've played with it without the gate. No deformations yet.

Slings , chokers or knots . No carabiners. Make it a safe practice and you will never have a blown out carabiner . Period !! No more dynamic load worries . Especially if you have employees .

agree with a half marl above the choked biner - I do that all the time
if you wanna see what can happen if you are just choking the rope off straight through he biner then go see my post in awakenings called got my arse whupped.

Yeah, it's got a very slight bend in it, I couldn't believe it. I wrote off to the manufacturer.

If they say anything besides that you weren't using it as directed and it isn't their fault, I will be surprised.
They might surprise, but there are so many warnings on those things that I really feel they have no reason to care, and they might actually be justified.

Those things come with a folded up book tied to every one, and almost all of it is "don't do any stuff".

I don't do big rigging with biners and don't personally feel great about it but.....

Is anyone able to make out that broken biner manufacturer posted by Chewbacca? If I'm not mistaken that is a type sold at cut rate prices and I would suspect it is produced in a country where dubious metallurgy is fine enough for whomever is gonna buy this thing.

Also for anyone interested in the use of biners in bigger rigging August Hunicke's latest video "5 Bucks" shows about 8 cycles on one.

I went and found the thread where they broke a steel biner.

I've posted previously that I use steel biners in rigging. Again .... I do ..... but for very light duty work.
Ie. When lassoing the tip of a small branch to keep it from hitting a window or out of lines ..... It's quicker for me to use the weight of the biner to my advantage. Then clip it on and run it. GM pulls branch up and clear. I only do this with light weight stuff requiring no friction control to lower on a pulley.

I use them all the time on my 1/2" rigging setups. Occasionally use a big, 70kN one on the 5/8" setup, but not for negative blocking.

But then, I don't Daniel Murphy half the tree in one shot...
