Broken aluminum ring

[ QUOTE ]
Would these be the same rings that wesspur sells? They appear identical.

Just recieved a large Al ring from Wesspur. ID etched on ring is USR-46-A 31356 24KN. Item # is CLI911. Appears to be a very nice ring for $4.25. I intend to use it on my bridge. Also picked up a smaller sst ring at West Marine. It was $14.00 and is not particularly smooth where welded together. It's made in Taiwan, don't know rating.
 
Hmm...crisis or opportunity? I'm sure the tree supply stores will be quick to offer steel versions of all the adjustable false crotch system variations to keep up with demand. Just throwing it out there...
 
everybody should note that this was documented about 3 years ago and i believe there was a recall on these rings(not sure where the rings in presant question were manufacturerd) made by US Rigging........

my advice to all end users and suppliers is that you should discontinue any use/sale of rings not stamped with manufacturer's ratings and discard/return them to manufacturer.

not only should you not use them, they should be disabled to prevent anyone else from using(if not going to be returned for testing)
 
Unreal.

I used to think the Petzl small (fully marked) aluminum ring was a little overpriced at 15 bucks. I've changed my mind.

In the past I've sold unmarked rings from Kong, ISC, and CT sadly without much of a thought. At least the CT's are marked with 'Made in Italy'. TreeStuff has a few dozen unmarked rings from ISC that are going in the trash can in the morning. Will probably stock the forthcoming fully marked CT rings.

Ha ha ha ha ha! I think I'm going to barf! Why on Earth did you not respond to these two earlier threads?!! Is this honestly the first time you've become aware of aluminum ring issues, whether sold by Sherrill or not?

Thank you TLHamel for bringing up the fragile nature of some of these aluminum rings way back in 2007. I remember your post, but I honestly didn't worry about it too much.

Everyone is acting like they didn't even see your post on this first page. I guess cause some would rather not respond to that.

Now that everyone is talking about it again, I will turn in my aluminum ring friction saver and one on my bridge. Both bought from Sherrill.

Good job Tobe and everyone that is making a big stink about this. This time it should reach lots of people and might save a life.
 
I'll respond.....hammers do not test anything...

Dont make it sound like stuff doesn't get recalled. Lots of climbing gear has been recalled over the years

However, this is serious oversight by a manafacture or retailer selling crappy stuff.
 
he saw stress cracks in it before the hammer by the way.

We'll stop that now... no need to discuss that old thread all over again.
 
In 2007 I wasn't a treebuzz member, nor did I ever hear of a recall.

I'm making a big stink because it's a big f'in deal

and guess what?

I'll continue to do so until every climber I know has been given the heads up.

Who made the gold-colored aluminum rings Sherrill used to sell? There is no rating stamp or name on those.

Should those be looked at again?

I was wondering the same thing. I called them yesterday and was told, "they aren't made out of gold, they are made of aluminum."

Then I clarified and was explained that they never sold a gold colored aluminum ring. Hmmm..

They are all getting sent back regardless!

gold rings would not be very well suited for tree work, that metal is pretty soft and heavy. Also expensive.

I'm trying to round up my rings. I might end up having to do
a lot of re-splicing. Probably not as much as Nick though!


Has anybody sent in any rings yet?
 
What we need is good steel rings. Whatever shop starts selling them first wins. For a few extra ounces the peace of mind is undoubtably worth it.

we need Ti rings.

[/ QUOTE ]

Before I retired, and started rec climbing ~ 2-1/2 years ago, I worked in an industry that specialized (among other things) in fabricating / welding Titanium (Ti).

Ti has the same "general picture" requirements as Al.

The alloy has to be correct; the fabrication (machining, forging, welding, casting, etc) has to be correct; the testing needs to be statistically correct; the source path needs to be traceable.

IMO ..........
Al alloys are fine if the correct procedures are followed.
Steel alloys are fine .............

Airplanes use an awful lot of Al (and Ti).

want a Ti ring try USHBA

For record's sake:

All hardware that is used in the Teufelberger products that Treemagineers are involved with is produced by DMM in Wales. Also, on the more recent rings you will see there is an individual number laser etched into the coating allowing complete tracability of the component.

Working with producers we know and feel happy with, who produce under conditions we are familiar with has always been a key target for us. Obviously this doesn't mean there can't be problems or issues but it makes these easier to sort.

One core issue to this whole matter of failing PPE is continuous quality control, rather than individual testing. You could also batch test every nth karabiner or whatever, so long as you have a quality assurance scheme in place.
