Big slings for big tops

[xtremetrees]

I like how cranes use big slings and straps for big limbs and tops.
I used to loop runners to increase my confidence on turning big limbs over houses and such.
1. attach strap to target limb.
2. Make notch.
3. Attch strap above notch and biner to below notch strap. (ensure steel only and double up on limbs over 2000 lbs.
4. Turn wood and hold using thin notch.Once limb turns and holds re-notch above rigging and fell.(Straps are useful as security incase the wood wont go the way your turning it.Try not to fell limbs with gear.

When rigging tops and heavy loads, I ensure the straps and slings will catch on lateral stubs or I dont use them. Expect bark seperation when choking with slings. Dont leave stubbs for something to hang on.

Carabiners and 2000lbs limbs?

hmmmmm

I need pics and diagrams of what you do mate to understand... please get a camera they are cheap these days and most will do some sort of video.

I am confused, are you saying you cut the limb hanging it on a strap and ****** and then attach the crane sling? I am also confused by turning limbs over? I would usually attach crane slings so pick would have the minimal movement, no shock load, when hooked proper, pick should come away from the tree in same position it was attached, no turning or flipping.

Can a carabiner safely support weight like that ?

Guys

This xtremetrees were talking about here.

He does the big stuff, quick, so he says.

Now, he's still alive and we havent heard of too many things being smashed.

But we never get any pics of what he's on about. I dont get a lot of his posts and he certainly is extreme in his ways.

So, please all encourage him to show us what he's on about, otherwise for all we know it's some kid making up stories.

Page 62 of The Art & Science of Practical Rigging I believe is what he is talking about. Only he doesn't chuck he cuts it free after clearing obstacle. I use it some for light rigging but slings don't stretch and you can't always eliminate shock loading.

I'll vouch he's not a kid. We met last year in Alabama after Ivan. I didn't get to see his work in action but from what we talked about it seemed as though he new his stuff.
I'll agree his postings seem very hard to comprehend.

I would go with a clevis instead of a carabiner.

One can reduce shockload with proper hinging, it does not have to slam down onto the rigging.

I've done similar things when it is problematic to use the rigging line.

Picture this;

you take two slings; one over and one under your knotch. This would replace a block under the knotch. Youare using the conected slings to catch the load.

What I usually use this for is to reduce a tip over a house, then rig the two pieces out from the connection. One is tip heavy, hanging the other but heavy. Usually this is a GRCS pick.
