X-rigging rings

You ain't seen nuthin yet!:loco:
hey TTF I went and looked into the properties of the Xrings after the rescue flame up and was pretty darn amazed at the integral strength of a torus shape and just how durable yet strong the hard coat anodising is with the ally.
actually agree with you if I do break a Xring before snapping the rigging or tree out then it will almost count as a miracle :reloco:
 
I love counting on miracles.:cool:
Don't break the tree ..don't break the sling..Don't break the line..but definitely don't break yourself in the process.. Even for crazy as you wanna get you ain't breakin the fuggin rings mate:banda:
 
I bent the edge in on one. It was used to pull split double leader together in a two to one. I dropped the spar sandwiching in the ring a bit. Tough enough and far less expensive than ruining a block.

Can you tell me more details as to what actually happened like impact wise ? What kind of pummeling actually occurred?
 
Double leader Chinese Elm approx 20"dia each stem, split around the 20' mark, peeled that banana, ring was anchor hitched to dyneema 9/16, wrapped around both stems then through the ring and tied off. So the one lead slammed and broke free from its point of attachment slamming against the the other lead in the fell. Job cost me the ring and an hour of fence repair. Lil yds and escaped Chinese Elm hedging and terrible pull angles. Think I still have it somewhere

I'm just catching up on some posts......
SRT climbing techniques, which were developed by vertical cavers in the 1950s and 1960s.
American caver Bill Cuddington, known as "Vertical Bill", developed the single rope technique (SRT) in the late 1950s.
Before you instruct your next rescue class you may want to check your history.
The first use of single rope technique with prusik and mechanical rope ascenders can be traced back to the exploration of the Dent de Crolles cave system in 1934. American caver Bill Cuddington developed the single rope techniques in the U.S. in the late 1950s.

Nice to see the arborist community catching up with us more than a half century later.
Who is this "us" that you speak of? Rescuers? Cavers?
Why re-invent the wheel? Take something good and improve on it, or at least show it to a different community that can benefit from it.
Most rope work have roots back to the sailing community, so I guess we are all catching up to them.

My thanks go to David for showing this community the X-rigging rings.
 
Maybe this has been discussed, but I don't really want to go through the 49 pages to find it.

When negative rigging with the THT, what prevents the rope from getting toasted on the bark? When using a block, or even multiple x rings, the rope it either protected by the sheaves or the rings are perpendicular to the trunk...keeping the rope off the tree. Where as, it appears the THT would pinch the rope between the THT holes and the tree because it is always going to be line with the trunk, causing a lot of wear and heat on the lowering line.

Good question. I guess the rings are like using a biner bark rub can happen but I've never had it be an issue for me. As for the tht that info and details are yet to be released but it is a question I wondered myself
