X-rigging rings

I have never taken classes on physics or learned by reading anything on rigging.

I just observe things and maybe rigging might come easy to me.

It might be my natural strong point, but I am subject to get things wrong I am sure. I am not a genius and don't want to pretend to be.

I'm just a tree guy that tries to do things smarter all the time, as the odds are stacking against me; the more tree removals that I do.
 
Oh, if you guys don't mind....

Call them X-Rigging Rings or else XRRs.

On the slings they can be XRR Slings.

Other rings at some point will be coming out and this will help to keep things staight by using the correct vocabulary.
 
Xman,

Got to take my hat of to you!

You are under the pump but you've come through with a good attitude and are answering everything that is asked of you, factually and honestly.

As far as salesmans go,I rate you, cause you were honest when pressed,and made good sense as well,straight away when questions where asked.

Tough it out X,.... we all know you'll do well!

PS. I base my rigging in trees the same way I see crane stucture, backload, backload, backload!

PPS. Backload!!!
 
If you think eucs stink after working with with them all day, try removing a camphor laurel on a day when temps are over 30 degrees celsius.

Those last, and biggest cuts,when you are using a big saw, and are close to the ground, really cook the oils and make your eyes sting like you woud'nt believe.
 
Thanks David. It makes sense to me now...

The point that fishing poles would only have one eye.... that made the most sense.
 
Another question, having watched the videos it seems that the single ring was pretty capable in of itself. Whats the reason behind having a 3 ring setup versus a traditional-style 2 ring setup similar to a ring-ring friction saver?

Another GREAT question.

A lot of you guys rope on a steel biner for medium and light rigging.

The single ring is much wider than any biner that I know of and yes, it is therefor way better than a biner for rigging.


If you are used to what a rope and biner can do, then sure, a single XRR could be used in that case and be way more safe and more friendly on the rope than a biner.

HOWEVER, everyone's skill level is different.

IF someone is going to mess up and break a rigging rope; I want it to break at the tie on the log.
I don't want our rings to be the location of a broken rigging rope.

That's why I'm officially going to keep saying "DO NOT USE A SINGLE RING AS YOUR TERMINAL RIGGING POINT. USE SINGLE RINGS AS REDIRECTS".

I will show in the next three diagrams (that I just drew up this morning) that I hope explains the bend radius of one ring, vs two rings, vs three rings on a sling.

In our severe drop testing, the rigging rope would break at the ring when using a single ring.

When using our tripple rings, the rigging rope would break at the marl tie on the log. THIS WAS A BIG DEAL!

The testing came first, then I comtemplated about it for quite a long time to figure out why.

I have been putting the three rings through hell at work, more and more so all the time.

I now beleive it is a stronger system than any block that has the SAME size diameter sling, but where the blocks sling is choked.

The tripple XRR sling is in BASKET FORM.

The weakest link in either the block with sling or rings and sling is going to be the sling. Not the block or the ring.

Therefor it will come down to what form you have the sling in.

Tripple XRR sling is in basket form.

Many people still choke a blocks sling.

The tripple XRR sling is now my favorite sling. I keep one on my saddle on large caritool all the time now. I like it because it's super strong, lightweight and I make it retrievable. Because it is lightweight, I don't feel the need to lower it with a throw line when retrieving, I just pull it out (in most cases, unless there is concrete or something). I have a heavy duty lowering tool on my saddle at all times. Which is great because i don't have to signal a groundperson and then haul up a heavy block.

Thanks Tom,

Everything just takes sooo much time.

I've spent three hours drawing those up this morning and posting, but I know it's worth it. And I can re-use them now, plus they will always be here for referrence and hopefully seen by quite a few.

I'm supposed to be finishing that video up for the XRR slings.

but I need to box up more rings and send to Rich.

That's what I'm doing next.

My tree service is really suffering, there are 17 messages on my answering machine and I haven't pushed play since Monday.

My tree service bank account is suffering too because we are short one climber and crane opporator if I'm staying in the office.

It's REALLY tough to juggle all this stuff and i just gotta keep putting out the biggest fire, when I wish I had time to do everything. I wish i had 5 more of me....
 
I was thinking the same thing. Guys ease up on all the questions until that video is done. Just kidding, it is worth it.

LOL... 17 messages... what a problem to have.

Tell mother to get that room ready, I'll be right out to fill in for you, at least until the video is ready.

Good thread, great product, and well done for making the concept available to arborists David. Looking forward to putting them to use.

If I'm honest though, the fishing pole theory, Ive never been sold on....because a tree is a tree and a fishing pole is a fishing pole. A rod must be and flexi and lightweight so you can cast, strike.....and not be adding to the weight when you're pulling in a fish.

If a tree takes a change of direction, is compromised, or I'm planning on going really heavy with the loading, then I'll redirect as need-be, or even as a backup in the event of the furthest rigging point failing. The crane photo and your adjoining tree diagram are good examples. I would think in most cases a tree endures far greater forces from wind-loading as it evolves and optimizes throughout its life than that from vertical loading/rigging.

The fishing pole theory, I dont know who thought of it first, is an option and worth bearing in mind, but I just dont buy it for rigging trees.

diagram 2, two rings. Same bend radius:

Physics says two rings are not the same as one and there are differences other than temperature.

The bend takes place over a longer section of rope with two rings Vs. one. The rope only seeing 90° of bend at each ring with even a small distance between the radii results in reduced rope stress similar to what is seen in larger Vs. smaller pully rigging.
 
I agree Reg, if the tree is bending like a fishing pole, you are doing something very wrong. Maybe when speedlining something like a counter line would be a benefit.
