X-rigging rings

... i have a dream...

smile.gif
 
Okay, so I've been reading this thread on and off, and like nearly everyone else, i'm looking forward to using some of these soon.

The place where I see myself using them soonest is on a big dead pine removal I've got coming up - i think i'll be using a dead-eye long single XRR near the lowering device as a redirect, and another one up top as a block replacement.

Only thing is, I guess I don't understand how I can use the 35" triple-ring XRR as a terminal block, as it isn't adjustable, and it is suggested to be used in basket configuration.

I think I understand correctly because of bend radius, etc., that the terminal block needs to be the triple XRR, and I don't think there is an adjustable one being offered yet.

Can anyone answer this for me? My other option, of course, is the old block up top, but I like the lessened weight.

Am I missing something? Trying to eliminate the block up top completely, not putting it in tandem with the ring(s), if possible.

Thanks for any/all input, and great innovation David!

Meg is working on her doctorate in molecular pharmacology. Her PHD should be done this year so we are looking at which law schools are best to get the JD...

My dad never lived to see it but I followed his advice: I married a doctor AND a lawyer and learned a trade on top of it all. :)

Stay-at-home-dad/contract tree climber here I come!!!!!!!!!!!!
 
I am doing estimates right now just checked in on my phone I will explain later there are ways to make 3 rings and make them ajustsble and choking

I would not think a block would add much weight your tree removal though. just skip breakfast
 
Bix, if I may call you that...

I was thinking about that, but I will say I've never operated with a true vsl before. In the past, I've run big big pieces to the ground, same concept I think, and it seems like with another xrr redirect at the base of the tree to direct the vsl , it might be a winning combo. Moreso than just hoping to miss the Stein Dual or POW.

Any further input? Vsl is def a poss in this setting, not much to miss, but can't just throw chunks either.

Thanks for your help on this concept.

Oh man Nick, that would be awesome! My girls are older now, but I would still have loved to have been able to do that.
 
Winch. I use a VSL like this:

Piece of old rope at the base of tree with old crappy biner. Rigging line choked around spar under cut with a biner. separate piece of rope cow hitched to log you are cutting, clove hitch with biner in it, Clip biner to rigging line(VSL). run rigging line down spar to crappy old biner at base, munter hitch the rigging line to the biner. Groundie steps back holding rigging line tight, you cut piece falls, groundie can allow as little or as much 'bounce os you like.

You can even aim the VSL in matter of speaking, see this picture:

It works great and there is no loading the stem. You can pin pretty big wood in a very small space.

Chris, its not really whether you care about Ken Palmers patent so much as whether the Patent Examiner cares! :)

Palmer's Patent reads for 2 DIFERENT sized rings if I'm not mistaken, David has 2 of the same sized rings, so a good Patent lawyer IMO would be able to defend him. If I'm wrong than you're right, I may be more concerned ;)

Prior art is what I was suggesting earlier....proving a false claim, so to speak. Its amazing what you can find if you dig deep enough.
 
Thanks guys, appreciate the info. Probably the way I'll go, but still interested in xmans input when he has the chance.

I love the diagrams, much thanks.

one time i showed up to see a tree.

most of the tree was gone, a storm broke it out and someone else cleaned up.

it was a red maple i think.

one lower limb was left.

the limb was excessively long and thin, as it grew out from under the crown to get to sunlight.

It was crazy long and thin.

maybe 6" diameter at the largest and maybe 80 feet long.

the customer had gardens under it.

nothing could be dropped.

too thin to go out to tip and do by hand.

plus, i don't like chunking down little stuff, a flaw i have.

anyway, i probably should have walked away from it but i was younger and i have never walked away (another flaw).

i rigged it with multiple blocks the whole way.

the idea was to give some strength maybe, but mainly as back ups in case the limb broke somewhere.

in case of a break, you need your climbing line under the block sling and lanyard over the block sling.

in a break, the lanyard would likely slip off, the climbing line would stay put.

then slowly decend, because your rope rubbing on the blocks sling.

So, in my opinion, the fishing pole tech can add multiple back ups to keep the peice from going all the way to the ground and also the climber.

if you seriously think something might break, my advice, don't do that job... but some of us feel we must.

I was probably on 3 or 4 inch diameters for my first few cuts.

groundman ran the line to gentle stops and nothing broke.

I liked having the idea of the backups while doing it.

I think most of what you've got there is a false sense of security.

A friction device as the rigging point on the limb being removed would have resulted in a load of only 1X the weight of the limb plus shock. A block or your rings result in a 2X load. The climber hanging with the load after the last rigging point breaks off taking the climber with it results in 2X the climbers weight plus 2X the limb weight. Not good and the climber would have been far better off to have been tied in lower and going for a swing.

What has been discussed before and would work great is a racheting block that held a wrap or two of rope for friction, freewheeled in one direction and locked up in the other.
 
TreeCo are you talking about a belay spool or mini porty for the rigging point in the tree.

And in at that case, going half way up the limb and making the cut would work?

With more of the low friction XRR's along the lanky limb it could only spread out the load along that limb.

In this situation you are better off to set up a pull line on the piece you are trying to rig and then break it out with you safely on the ground.
I ahve done this. Set up rigging-make a partial cut-descend and snap or break out the piece.
Cheers
 
or set up a VSl with the limb tied to a descender of your choice(f8) and to catch and slow its fall with a control line. I guess you could shake the tail of the rope as well to slow it down more. This way you will have a true 1x the load on your Rig point. A lowering device in th tree like a spool wood still be 2x load.
Cheers
 
Or send up a 2x6 or 4x4 and straps to brace the limb at the weak point

Or rig cut the limb onto a spider web of ropes that catch it before it hits the ground

Or accordion cut to bring it close enough to the ground
so that the impact is small

Thats all the ways of done it. Any one else!

Once at a Vermeer rigging seminar the idea of using a sander and turning the wood into dust was tossed out with a chuckle.
 
Winch - as per," missing something?"
How about using two XXR Loopies X616S or X616L and the X6159S
Sling, all pictured in David's earlier post (#34320 on 11/23/12) this thread? Notice the inset photo has them put together.
