Re-direct question...

[sac-climber]

I often use a girth hitched nylon sling and carabiner for a quick re-direct when limb walking certain trees. My question is am I still within ANSI standards if its a screwgate biner? Anything attached to my saddle is auto-locking.

As I recall, has to require two distinct motions to unlock if its for life support.

 

[sac-climber]

So is unscrewing and opening the gate considered two motions?

 

[imagineero]

No. Just get a triact. They're only a few bucks.

 

[sac-climber]

Thanks guys....think I want to buy a rope wrench anyways so I might as well blow a few bucks on some more biners.

I use non-lockers for redirects, quicker and easier to one-hand, and since they aren't directly in your life support system, I don't see an ANSI issue. Just make sure you load the biners the right direction.

Screw gate biners are used in rock climbing why wouldn't they be certified for life support in tree climbing???

Rock climbing is not a job covered by regulations. You can use anything you want, clothesline rope, plastic carabiners, anything at all ;-)

You can't use pretty much any of the gear you use for rock climbing for roped access work, not even the ropes or harnesses. The descenders are also different, so no surprise that there is a higher requirement for carabiners too. I prefer tri lock, it's just that I've still got so many screwgates hanging around. I tend to use them for light rigging and misc tasks (a lot of those!) and not for primary life support. If you do use them for misc jobs like attaching a saw to a lanyard or whatever you'll notice how often they open of their own free accord!

Rock climbing is not industrial access, work positioning or tree climbing. The rope is there only as a backup.

Good point. Never though of looking at it that ones a job and ones a hobby.

On a side note. Try using a Munter hitch on the biner redirect (but has to be locking). Works better than just putting your rope through it.

What advantage have you found by using it?

 

[gorman]

When using a smaller limb for a redirect, it distributes your weight better and eliminates some of the increase of force on that point. It also doesn't act a pulley, pulling your tie in points together.
Try it. You'll get what I mean. This is mostly for smaller limbs agains.

 

[imagineero]

I gotta admit, I can't even picture what you're trying to say. Can you draw a diagram or something?

 

[gorman]

I'll draw a pic when i get home. I am talking srt in this scenario.

 

[imagineero]

Ok, I get it now. Adding SRT to it made it make a lot more sense. I would have thought the pulley effect would be pretty minor considering the angles are likely to be kinda small, but every little bit counts. I have a habit of redirecting off very small stuff too, and always interested in seeing how far I can push it when there are no consequences. I've redirected off stuff as small as 3/4", admittedly at a very small redirect angle. I'm on doubled rope for working, so I use a double sheave pulley for my redirect.

So I guess that gets me out of having draw a picture?

It's not just you, most the time thats all there is when you need to shift your load the most.
