Super Quick 3:1

Fair enough. I was thinking the fact that it is light in weight, and useful for more than one purpose (as an actual life-support rated ascender, for example) might be mitigating factors.

Your primary and probably correct focus is to have the smallest, lightest, most quickly deployable 3 to 1 mechanical advantage system it is possible to devise, is what it sounds like. (Edit: Tyler posted the comment above while I was writing this post, and before I had the chance to post my comments, which is why it sounds like I'm repeating the obvious. We in fact were working simultaneously, and in isolation.)

This is an interesting objective to have, and I look forward to seeing where this thread goes.

I love this: I use it as a bridge adjuster and it easily doubles as a quick 3:1. It doesn't have the sharp teeth that the tribloc has and is just so much more better. It works well with a Rock-O.

Hey, Tyler! It seems like John probably came up with the best solution. It's hard to imagine an ascender getting much smaller than the device he mentioned.

One thing that concerned me was whether or not it was midline attachable. From the product description on Amazon, it appears the device may have swing cheeks that do make it midline attachable.

I'm not sure if either TreeStuff or Sherrill sell this item for some reason. I did not find it in either place with a quick search.

Here's the link to the Amazon page.

Tibloc has a bad rap, primarily associated with people using it standalone for vertical ascent in the mountaineering world etc. The teeth are no more aggressive than a Pantin foot ascender or any Petzl toothed cam ascender. Which also have a bad rap for picking strands. For use as a quick 3:1 return from a limbwalk I think it can work. In a 3:1 the Tibloc is just holding the redirect, in a shock load scenario it takes no load, your wrench or multi-cender device and rope takes the load. If you understand how to use it, put it on and take it off the rope without picking the rope it should work but... It's not exactly convenient to push it up the rope for your next pull on a 3:1 return. A Microcender would be excellent, it's small, relatively light and quick on/off the rope, no teeth to snag fibers when you're taking it off the rope.

I see a lot of you use a micro pulley in your MA. Do you really think this is making that much of a difference at the end of the day? Pulling up my body weight plus a saw on a 3:1 built with a hitchclimber and a Rock-O has never seamed like a chore. I switched to SRT after DdRT for years on natural crotches most of the time, so any MA just feels like pulling slack through the system to me.

Tim I secretly linked the photo of the Roll N Lock in my other post, to the treestuff listing http://www.treestuff.com/store/catalog.asp?category_id=193&item=12216
It's in with the rope grabs. And Yeah, I couldn't find it on Sherrilltree either.

This was a great point, and something that I had not really considered before. The only time any force gets exerted on the 3 to 1 is when you are actively pulling yourself back up, and that amount of force seems fairly minor.

Thanks for this post.

Hey, Tyler, please forgive my confusion here. When you used a Hitch Climber pulley with a Rock-O carabiner for a 3 to 1 mechanical advantage, what was holding that assembly to your climbing rope? The way I would picture it happening, you'd have an eye to eye piece of hitch cord going from biner to rope and tied into some form of climber's hitch. Then you'd be left with the Hitch Climber pulley hanging down, through which you'd pass the tail of your climbing line, thereby establishing your 3 to 1 mechanical advantage, with a fairly large diameter pulley giving you an assist. Otherwise, all you'd need would be the biner and hitch cord.

So, what am I missing here; I'm having a tough time picturing it, for some reason.

Thanks in advance for any response.

Tim and Moss, I figured there wouldn't be too much force on the tibloc in this application as well. I don't plan on using it as an ascender, just a "rope clamp" or "mechanical knot". I am a production and competition climber so I am trying to make a simple, fast, light system I can deploy and hang up in as few motions as possible.

Tim, I use a VT hitch with a rope wrench and oceans tether connected to a hitchclimber with a rock-o.

Tyler, so that is your standard SRT setup, which is only a 1:1 ratio. Earlier you made mention of using a 3:1 mechanical advantage setup somehow.

This is your quote: "Pulling up my body weight plus a saw on a 3:1 built with a hitchclimber and a Rock-O has never seamed like a chore." This 3:1 would have to be in addition to your standard Rope Wrench setup, if I'm thinking correctly. It would sit above the top of your Rope Wrench setup, and the tail of the rope that left the underside of your Hitch Climber pulley would need to loop up and through a biner or pulley that is held in place above your Rope Wrench/Hitch Climber SRT rig. It is the extra two legs of rope that go up to the higher pulley and back down again to your hands that creates the 3:1 mechanical advantage. The question is, when you say you created a 3:1, did you in fact have another pulley sitting above your Rope Wrench?

I guess my most basic question is, how were you making your Rope Wrench setup change to create a 3-1 mechanical advantage configuration?

Apologies if I seem dense, just trying to understand. Thanks for your patience with me.

@Tyler Durden , when you say you're looking for small and light, etc, I can totally relate to where you're coming from. In light of this, I have learned a few things over the years in countless attempts to get there. I think one of the best lessons learned was that VERSATILITY can translate into what you're after.

If you had 5 single function tools on your saddle, you could be better off with 2 or 3 versatile tools. It's absolutely key to me. The thimble prusik can wrap around one or two legs of line, it can be purposed into a component of other on the fly uses, and in English Prusik config, it can be loaded either direction. No mini-ascender can do what a thimble prusik can, and all without the worry of potential rope damage.

This is always just my $0.02, so take it with a grain of salt. I carry 2 with me on every climb, not including the one on the working end of my lanyard. Love that rope tool!

I just had to go along with Paul's sentiment on spelling, but also change "Tibloc" to "thimble prusik" because I prefer it so much. I wasn't sure how many would actually get my joke.;)

By the way, choosing one of the smiley faces from the screen of a mobile phone is somewhat nerve wracking. I'm usually afraid I've chosen the one giving the finger instead of thumbs up!

I think you are hilarious. And you definitely win with the thimble prusik. :fuckyou: The one thing the prusik can't do is work as a bridge length adjuster. I need to get the official thimble prusik to see just how right you are. I have a homemade one and I also have the sterling adjustable loop with the soft tighten-able eye sort of feature.
I have the Roll N Lock with me always as a bridge adjuster and I love it, but that doesn't make it best for everything. I think it is bester than the Tribilock though!:rayos:

And this is what I think of you -> (y)


...:) what was my intention? so very unclear...:sisi::endesacuerdo:
 
Most of the time when I want a tail tender for SRT I tie a slip knot in my line then clip a locking Revolver biner. It's rare that I ever make this setup with tension on my climbing line. When it is under tension I use a cord/webbing sling to tie a Klemheist and choke a Revolver.

Tibloc translates into 'rope shredder'! I use mine on the pull-down for my Big Shot. Before this use it resided in the Ascender/Descender bucket for years!
 
Tom, more so than any Petzl toothed cam ascender? It's clearly terrible as a standalone ascender but as a supplementary device that doesn't see any more load than say a Pantin, is there a difference?
