In this video we look at using snatch rings, X-Rigging rings, blocks, and pulleys to create different mechanical advantage setups for tree work.
Efficiency ratings:
5/8" CMI Block - 91.2%
X-Rigging Beast Ring, loaded "snatch" style - 79.5%
Schtumpa snatch ring - 75.2%
7/8" Steel shackle - 62.5%
DMM Steel Carabiner - 59.8%
2:1 Pull Testing
CMI Block - 2.0 : 1
X-Ring - 1.86:1
Snatch Ring - 1.71:1
Trucker's Hitch 3:1 setup
with Snatch Rings - 2.35:1
with pulleys - 2.88:1
Spanish Burton 4:1 setup (2:1 on a 2:1)
with Snatch Rings - 2.88:1
with 1 X-Ring and 1 Snatch Ring - 3.02:1

That was a very impressive, time-consuming experiment. It is men such as yourself that are the pioneers in advancing tree work to be safer, and more efficient.

Great, informative vid, Patrick! Thanks for the testing numbers. I've been using "Snatch-Rings" for a couple of years after smashing a block against a rock. I work in a lot of 'hardscape' - pavement & rocky ground. So, the cost of the Soft-Shackle should, also, be figured into the gear-at-risk if damage occurs. I make my own Soft-Shakles which further reduces the cost of gear-at-risk. I *only* use "Snatch-Rings" in situations where an expensive block might get damaged. I use "Snatch-Blocks" in all the other locations where they are 'safer' from damage; Z-rig, anchors, redirects, etc. That way I only sacrifice efficiency in the location(s) where damage is might occur. Again, GREAT VID - thank you sir!

Nice video. Spanish Burton is what I use in my vehicle recovery kit. The size of the rope has a lot to do with the efficiency of the rigging ring. Looks like you were sometimes running a 5/8 or 3/4” rope in a rigging ring meant for a 1/2” winch rope. If the rope has to Squeeze itself in and out of the ring, that probably has a lot to do with the friction loss. Looks like the X Ring has a lot more room for the bigger rope. Thanks for sharing, gives me some ideas about what to expect from my kit.

Yep Snatch rings are awesome. I have a few of them with soft shackles.

I use a dead-eye beast ring for this purpose 🤙 works superb

I don't recommend using snatch rings for rigging in the tree. I tried it in a negative rigging and the rope jumped out of the ring. It ended up melting a groove in the anchor sling.

Yeah that is definitely what would happen. The rope jumped out of these 2 rings more than once while setting up these tests.... - Patrick

I was thinking the same thing. If the pulling rope gets a mind of its own, it might fall out of that groove. If your lucky, you could still re-climb it and fix or omit it. If it pops out when it’s show time… Because of the risk of crushing gear, I don’t add that 2:1 pulley on the peg, but if I thought I needed the extra force multiplier, I think I’d rather just use a ring sling and write it off if it hits hard.

@@jtr109 My setup was negative rigging on a beast ring. It was girth hitched on the eye of a 5/8" tenex sling. The increased bend radius was good, but the 1/2" rigging line jumped out of the groove. No major problems beyond that learning experience.

@chrisw5742 7 ай бұрын

they make rings with little rubber rope holders that make it so the rope doesn't fall out.

Great video, very informative. Would have loved to seen the x-ring tested in the same way but swapped where they are choked with the load line going through the center like we use them as a redirect. No doubt it’s worse due to the tighter bend and higher friction but how much worse because that way they won’t jump out of the U- notch 👍🏼👍🏼

@brandonswan9247 6 сағат бұрын

Have you tried to lubricate the ring with some sort of oil to decrease the friction thus increasing efficiency?

@chrisdaunhauer1757 Жыл бұрын

Great content as usual. Thanks for the effort. My question is HOW would I know that I have "smashed" any of my rigging gear to the extent it should be condemned (?) If a errant chunk lands on a ring or pulley (of any level of quality or cost), is the mere absence of bends or cracks in it enough to maintain my confidence in it ?

Wow, you did some great testing on those x/snatch rings/blocks. It's interesting to see the efficiency of each vary so much. I'm just looking into doing some climbing & down rigging now that my son is old enough to be the down guy. Do you have a video that you recommend for climbing. I've seen some of your fishing 🎣 pole techniques on rigging which really dumb it down for me.

I would love to give you the opportunity to understand about a mechanical device that I have invented that is by far the strongest on the market #zrunner is the mechanical device that is midline attachable made out of stainless steel and it has all of the configurations needed for SRT and DRT climbing scenarios.
