Cord attachement to Fixe

This came up in a thread over at arboristsite.com
and since I didn't get a straight answer, I'll try here as well.
I've seen some people attach attach one end of their
hitch cord directly to the end of a Fixe pulley with a
barrell knot/dbl fisherman, instead of both ends to the carabiner. See attached image.
Some benefits would be less stuff on the carabiner and
less chance to loose the pulley.
But, is it really ok to do this ?
Would such a setup pass the gear check at a competition ?
Would it be ok with the OSHA (or whatever your govermental
inspection agency is called) ?

Government inspection agency? Is there such a thing?
In regards to your question...I don't see why one would do such a thing. However, I haven't tried it yet. I will do so at work tomorrow. I will report back tomorrow evening!

there are two reasons I would not tie a knort to that part of the fixe: 1) unlike the nice round surface of a carabiner that end is just a flat piece of metal (a big no no given that bend ratio kink type issue)2)tying one end of your system thu this part of the fixe would put part of your hitch cord (sometimes) in direct contact with your climb line, and as you descend that one spot would recieve a lot of wear. overall, I would consider it to be an unsound method.
 
I have been using this system for over 4 years now with my split tail spliced to the Fixe and have not had one problem! I am using 9mm Samson ultra tech (approx. 7000lbs rating) spliced with a double locking brummel. In a dynamic system only 25% of ones body weight is on one any part of the system. The becket on the pulley has a really good spread and does not have sharp edges. A carabiner has a sharper bend radius then the becket on the Fixe. We contacted a Petzl rep and after looking into it he said there was no problem with this application of the pulley. The rating on the pulley applies to the becket as well. I am using this one until early next year when it will be sent into Samson to be pull tested along with an unused system, I will post the results after the test.

Jason,
Please do not knock something that you have not tried, set up the system and have a look at it before you dimiss it.
 
Craig, what friction hitch do you use, and which part of the pulley to you mean when you say "beckett?" I assumed what hillbilly was talking about was the eyes the carabiner goes through. I tried that today. I had one side of the friction hitch tied to the pulley, tied the knot, then just put the other eye on the carabiner as usual. I was using a 3/1 distel. 7/16 Yale UULS on 1/2" XTC. First, it was a pain getting the rope onto the pulley, and second, having the knot tied that way made the distel stay way open! It never locked up on it's own. Great for slack tending, but useless for everything else. I'd have to see how someone is using this setup successfully so that I could understand the benefits. For now, I give it a thumbs down.

Nick,

I use a modified V.T. for my friction hitch. Here is a photo of someone elses rig I pulled off the net, the only difference with mine is the length of the rope, type of rope and mine is spliced.

Ohhhh! Now that's a whole nother story! (Is "nother" a word) If you look at the pic, you can see where I was tying into. You can imagine the pain of getting the carabiner through that tiny hole when there is a rope in it already! Ok, I'll try this tomorrow to see what I think. I'm sticking with the distel, though.

Wish me luck!

"Government inspection agency? Is there such a thing?"
You tell me.

Sorry if I was unclear about the attachment point Nick.
The pic Craig posted is what I meant.
While this rig is probably strong enough, it has
no rating for this use. The 22 kn rating applies when
the pulley is loaded thru the carabiner holes and over the
sheave. So, would it pass the gear check at a competition ?
I know there are some gear inspectors browsing this forum
that could perhaps answer.
Looking forward to hearing the results from the pull test
Craig !
 
Iv'e been told that the setup that Craig showed is legitimate in the TCC. It would be best if the word from Petzl were printed and brought to the competition.

W-O-W

So on friday (the 4th) I set up my distel to use while removing a Honey Locust. I don't know what it was, but everything was working so smoothly! Just when I thought it couldn't get any better!

The biggest complaint with the distel is that you often have to re-dress by flipping over the top part that get's curled back the wrong way. For some reason, I only did this a few times and it was out of habit, not out of necessity. I'm going to leave it like this for a while. I just may splice some of this 7/16th's UULS directly to the pulley...who knows!

Re: W-O-W

Nick,

I am glad all went well and that you like the system. I have yet to find another system that beats it, thats why I have been using it for the past 4 years.
 
Re: W-O-W

I think the becket is load rated. It is not just some extra hunk of metal, it is there to tie a rope end to, for creating a 2 to 1 set up. If you look at it you will see it gently bends to form a radius, and has nicely rounded edges.

Craig, that's my photo you stole off the net. I won't charge you my normal 25 cents, each time someone clicks on it, because i think it was you who gave me the idea to use this set up, over at the ISA message board about 3 years ago, right?
 
Re: W-O-W

Mike,

That is correct, I remember dropping you a line on the use of the set up !

I did'nt have a photo of my own but I remembered seeing one somewhere. Anyways, how are you liking the system?
 
Re: W-O-W

"It is not just some extra hunk of metal, it is there to tie a rope end to"

I can't see it, in fact I can't find that information anywhere.
Good idea but I don't think Petzl designed it for that purpose.
 
Re: W-O-W

Sorry Tom, I don't have such a thing,
what I said was that I "would like to see it".
I might just write a mail to Petzl and ask about
this use. I'll post the reply here, when I get it.
 
Re: W-O-W

I spoke with a friend of mine at Petzl today. He said that the rating for the becket is @ 5000#. He could not comment on this particular use "officially", but said that the issue would probably be rope shear.

Rope shear would be most probable at 2500# or so (I was told that there was some testing done on this), so it would be highly unlikely to happen with a climber's weight. All things considered, it might even be imposible?
 
slipping knot

I'd like to think that the friction hitch would slip down the host line before the beckett actually sheared the rope. I wonder where a distel slips at?
