Back On The Becket!!!

[rahtreelimbs]

I was at the Tree Climbers Jamboree last week and heard a few guys are climbing using the Petzel fixed micopulley. I know this is nothing new but has anyone experienced wear on the tress cord where it ties to the becket?

 

[Kneejerk Bombas]

I've also gone away from using the cord this way for the reason Brian discribed.
In the time I used it, I never had wear there. The becket is smoothly radiused and without any sharp edges.

I have been using this system for some time now and to be honest the only thing I like about it is not having to deal with a second fishermans not and the pulley the one side of my cord stays on the krab and i can just tie the knot slip the fixie around the rope and on the krab and I'm good it takes one less step,Iwill take a closer look to see if my hitch reacts as you describe

I the fixe is only rated at 22kn. If used just for slack tending it is fine used in this fashion. I would guess one could argue its compliance with ansi when its tied to the tress cord. Maybe if I see anyone use it that way in compition I can argue it and have them DQed accept you Jim, that would be like turning a family member into the police. I wouldn't be the climber I am today if I had never of met you.

 

[Kneejerk Bombas]

The pulley only takes half the load the climbing line takes, and even less if you consider hitch slippage, so that's an invalid arguement in worlds other than climbing competitions.

 

[Tim Gardner]

Would the part the cord is tied to have the same 22kn rating? Has anyone actually tested it? The reason I ask is because the 5,000 lb standard is there in case something goes wrong not for everyday use. My brother survived his climbing accident because his saddle held when a log got hung up on his gear when it came over.

 

[Kneejerk Bombas]

The pulley shouldn't need moore strength than the tresse cord, should it?

 

[TheTreeSpyder]

Ummmmm 1/2 the trees cord load(if balanced loading of legs), which the tress as a whole carries half your weight force on 2 legs, pulley is only on 1? But then the tress cord is a disposable item, that the pulley is expected to take abuse from many of tress cords lives.

 

[Tim Gardner]

Even if that part of the pulley could handle a 1,250 lb load, would the shape of it not weaken the rope?

 

[jkrueger]

I've been tying to the pulley with one end of the hitch cord since I saw Jims pics of his set up compared to Big John's, think John was also using that when we did a day off climb together.

Of course I don't do heavy production work like many of you guys/gals? so my experience of defered strength ratios isn't as critical. Oooops, should never have said that, the thought was I do not worry about something big hanging my climbing line and me and the line having to take the shock. The oops, is that when ever I say something definitive for my self here it happens contrary in a day or two.

I have to drop a large brach on an old oak tomorrow, it is 26-30 at the leader. As big as some trees. Dah, I've give it thought and even though I'll be working alone don't see any problem. Bless me, bless me.:angel:

Could not help the extra stuff connected to the hitch. Sorry, "Working Alone and Other Confussion", was a serise of books I once published. Gee, still doing it.

I think part of the prob is that ANSI needs to be more clear about what is permitted for the use of friction hitches. Can someone look that up for me. I'll try to check it out later tonight.

I agree with what everyone here has said so far, I first saw this a few weeks ago. I was questioning this whole idea, after a little thought the main thing that bothers me is that bend radius is terrible. This can't wear well on the cord.

 

[Nathan Wreyford]

As rocky said, good idea, poor performance. To some it may not matter. I like my rope to tend its own slack just with the weight of the tail.

I saw some of the Euro crowd using this in March. Since then, I have had a few of the competitive climbers show me a hitch that is better.

Rocky likes a 4:1 vt. Good performance What they turned me on to was a total of 5 also but instead a 3:2. It usually self tails when starting from the ground. Length is more critical with this than a 4:2. It is easy to get a configuration that won't bite.

I prefer to stay away from the becket thing. To each his own.

 

[NickfromWI]

I used the becket for a while, but it just seemed that the friction hitch was locking up tighter than it should. I left that idea after about 2 days. If performance increased, I'd stick with it, regardless of the bend ratio. That would be a wear point that you could/should inspect on a daily basis. You would see when it was getting ready for retirement.

That being said, I've been doing a 5 wrap, 4 braid VT lately. I kinda just tried it on a whim using some 5/16th cord. I am liking it a lot!

Have any of you gearheads found the mechinism that causes the becket tied hitch to grab too much?
If'in you could figure that out, youse might be able to figure how to resolve the issue. 'cus it is real nice having the pulley tied on the end of the tresse cord.

 

[Kneejerk Bombas]

So then a screwlink attached to the becket would take care of this problem, thanks.

 

[Kneejerk Bombas]

So we need to take the flop out of the connection between the fair lead and the binner...that'll take a little more thought... or duct tape!
Thanks!
