X-rigging rings

IMG_8558.JPG
 
Okay buzzers, I'm making time to reply to you. I've been dying to respond, just so much to do. Can't stay up late though, big nasty uprooted tree to do tomorrow at 40% lean and lots of tension and pressure points due to it laying on many other trees.

I will talk from the beginning, just like I did at the show to many of you.

I have been using these rings for almost a year now at work. I was using them as re-directs in rigging but also as my top or terminal rigging point. For most of the time, my top rigging point was a SINGLE ring! This is not going to be an acceptable practice and will be cautioned against this in the instructions. (Due to the bend ratio and what we learned in shock load testing)

BUT, this was important to learn from. Because a single ring is going to get more heat and be harder on the rope. When I first started using them, I thought, well, they might work okay, but I bet they will get too hot....

I was amazed.

They are aluminum, highly polished, then HARDCOAT ANODIZED. Don't think of it as a coating, it penetrates into the aluminum and also adds some thickness. It makes the surface as hard as hardened tool steel.

It is so incredibly low friction and perhaps since hardcoat is non-conductive, it does not get very warm.
On normal rigging, when I touched the ring right after a run, it was slightly warm.
One time, I had another spar tip tied. The rigging point was a single ring. I notched it and the guys cranked it toward the rigging point with the grcs. I then had them raise it all the way to the ring. I then climbed up to the ring. Once I was there, I told them let it run really fast to the ground and slow to a stop before hitting the customers yard. I think it was about 12 to 14 inch diameter and 15 to 18 feet long, Liriodendron tulipifera log. The run to the ground was likely around 65 feet. They did as I asked; it could have been a little faster. I grabbed the ring lightly and it was warm, I firmed my grip and then after about 5 seconds I’d release my hand because it was a little uncomfortable, I would squeeze again, and say to myself again, “okay, that’s a little bit of heat”. That blew me away, I knew right then, this was something big. If that was a steel biner or clevis, I would have been burned. People tell me temperature that is uncomfortable in 5 seconds is probably 120 degrees. Now remember, that was using ONE ring with tight bend ratio, a fast run and decent weight. Polyester slings can become damaged or weak in temperature of 194 degrees and above. Our ropes have NOT been getting glazed either.
I gotta go, it’s almost 11pm.
I want to talk about bend ratio and three rings as a rigging point, plus talk about using a block and ring together as top rigging point. I’ll say this right now. BASKET FORM! And both can be set from the ground and retrieved from the ground, SAFELY.

I gotta stop writting for now.

Prices and availability will be set VERY SOON!
I will contribute more to this thread this weekend.

Thanks,
 
also, I have a blog up (I'm learning, but the navigation around the site is irritating me)

It will likely be where I will show the various slings available and the prices. And how to order.

I linked Xtreme Arborist Supply domain to it.

Oh! And I've tried to change youtube to allow mobile devices and for some reason it said I can NOT change it.
 
The X-Rings would get my 'WOW!' award for the show.

If the Hitch Hiker would have been unveiled there it would have been a toss-up between the two ;)

David has taken the ring/ring false crotch that we've been using for a long time and jumped it up a few orders of magnitude. Setting and retrieving the rings or ring/pulley setup remotely really enhances their use.

It would be easy to get temps using something like this:

Cheap infrared thermometer
 
I like the concept . i want to use them . My two concerns are that the heat might hit the eye of the sling and you have to feed the line thru them . We'll see , can't wait to use them . My feed back will be honest and work true .
 
The rings look very nice!

Well done X!

Question is ..what is the price!!!

This product is competing against a tried and tested method,that is using pullies.

Most people already have blocks.

As we all know, blocks do a great job, and the only reason I would replace my block is that it is worn out.

The x rings would have to be significatley cheaper than a block to purchase in favour of a a block.

A Block far out ways a ring with its capabilities.

X ring is a great product but its got to be priced right and optioned .ie. not sold compulsory with spliced slings.


PS. I reckon the rings are a great product
 
Chop, I really like that kind of thinking. And you are dead right.

BUT ...
Don't think about the rings replacing your block but cooperating with it.



I can see a system that gets your block to punch way above it's weight class and makes it remote install/retrieve ... !


I am so excited about David's X-Rings, I can't wait to get my hands on them.

I dont see these as competimg with blocks. Blocks are heavy and have no friction. I do reckon though if they are only sold with splices, the first thing ill do is hack off the splice and play with my own configurations which would be a shame. Ive alteady been thinking about how i want em done which is somewhat different than how X had them spliced and rigged at TCIA.
 
Why didn't you go with a captive ring? I'm thinking about the thimbles that dmm is putting out. It seems like they would add a bit more security and splicing options if the rings could capture the rope.
 
The secret weapon is a removable floating false crotch. Picture a ring 'n ring friction saver made out of hitch chord that can be installed on an access line via a VT or the like. Having the large ring/small ring set up in conjunction with a VT type knot allows it to be retrievable.

Oh, I thought it would be more sexy than that.

You could make one then hang nudie pictures on it. That would sexy it up a bit.
