Remote| removable| retrievable| redirect system?

MTS247

Any one got any good removable redirect systems? I've seen one on this forum that used a prussic knot, i forget who posted it but id like to know about your experiences.

There's the "retrievable M rig" which Scott Prophet I think came up with well publicized since @2003.

I'll see if I can get some pictures up soon, I take it what you are after is a redirect where the climber doesn't have to return or change his high point to get it out of the DRT loop.

I might go down the park and get some examples for you, no rocket science here.

I think it was quercus that had a nice looking prussic type redirect but i can seem to find it again

Sorry about the drawing but my camera is busted.
I think you get the idea.

You mean something like this??

I use it, and it's ideal in many ways. You can attach it anywhere, saves a lot of friciton and is retrievable and can be installed from the ground.

Im still trying to work out how that works

Eric Frei

Ooops, knew I forgot something, I'll get around to it one day.

MTS, that's an ART rope Guide, climb on them as your high point and you'll never look back.

This video shows one and using installing retrieving etc.

i know what it is, but can it be used as a redirect? that can be removed while in the tree

Eric Frei

No, neither can or should the cocoon pulley unless you have two of the bloody things.

You also need swivelling pulleys so you dont have to feed your rope through, however lets say you use a dual pulley girth hitched to the tree then it's not going to be retrievable although a great redirect.

Hard to explain, need pics or video showing.

Ill get some pics up soon of one im working on that uses an ascender

MTS247

Ok so its not a working pic but i think you get the idea.
The rope on the right is the climbing line through a double pully, ok so lets say you have finished with the redirect and want to keep working in the other side of the tree you just pull on the string and the redirect will come out and slid down you climbing line, just remember it will be coming down at a fairly quick so you might want to put a quick litle hitch in your line above your prussic.

Oh yeah the string is tied to the cam of the ascender

Innovative but I think it's risky.

And also having another bit of string is just another PITA to have up the tree. Using the tail of the climbing line is better, it's there and not an extra, that's the tail beneath the friction hitch you climb on.

But hey, more ideas the better.

Risky please explain? remembering that all removable "redirects" will "remove" when the "tail or line" is pulled, i like this one because you have to pull 1.5m of rope before it will release. the other ones that are knot based only require i slight tug and they are undone.

The tail of you climbing line could be attached to the string. but the weight of the climbing line could activate the cam, but only when there is no weight on the system.

Im looking for somthing to use in a comp so it has to slide down the rope rather than hit the ground.

MTS247

Close up.
I'v seen some redirects used in comps and they all have their problems and this one is no different, and when using them climbers should be aware that they could come undone, and just so there are no mistakes this is not a main attachment just a system to "redirect" the climbing line.

Maybe a microjuster would be better in place of the ascender

Have u seen the ropeman ascender? same thing just smaller ( may not be suitable for comps)

You can also use a prussic. the string is attached to a small clip above the prussic and will slide out when pulled

sorry no photos yet



only problem is that can create a loop that branches can catch and pull on redirect or rope might not be long enough

PTC

How often does the ring get stuck?

willem

mts247, your right i made a mistake. The device isn't a good redirect for two ropes. And yes you have to pull the rope through to get it out. But as a high intie point it's great.
Never seen the redirect you made but I will keep an eye open for such a system.

PTC, untill now I haven't had the ring getting stuck. But every time you retrieve it is exciting. The reduction of friction is realy great certainly when your climbing big trees and have to go up and down a lot.
Also great when you don't have a good anchorpoint you can tie it around a bib branch or the stem and pull it thight.

Eric Frei

OK

I sketched something up.

You have your original high point up to the right.

You then get the terminal end and thread it through a FS (little hole first ) and click it off to your saddle as per the normal way you climbed. Put a biner (DDM Revolver) to your saddle so the new loop of rope for the redirect hugs your saddle.

This should work using the old prussick, you shouldn't fall into the "V" but if not happy with this system whack another prussick shown in green into the system.

This way you maintain the high point and can retrieve the redirect.

To retrieve you tie a knot (as per normal) in the left hand terminal end, pull it through the big loop and of course it doesn't go through the little loop and wella, as long as you don't drop the rope you get the FS back and have maintained the original high point.

Thanks for that i never thought of using the termination end

Nice! I will just use a second rope naturally if it a removal or a big thick barked tree, or if not I will just use a sling and pulley and climb my fat ass back up there to remove it, LOL.

The trick with the FS with the two sized rings has never worked very well for me, the rings don't like to pull through the crotches.

Your system only requires pulling through the rope, I like it! Definately some risks to consider though.

This is what we call a double loop system, I used to climb with this system one rope with two eyes and a prusik on every eye. Nowadays I climb with a the same rope but only use one eye together with a flipline. But I always carry an extra biner and a prussikloop with me. When I get into a situation where i need a second anchorpoint or lets called it a redirect I hoist up the other end and make the second anchorpoint with the other eye and the prussik.

PTC

Thats the "M" rig. Very usefull, but different to a redirect.

fosheezy

heres a pretty good retreivable redirect system. The false crotch contains a biner and pully on the rope bit with the prussic, and a biner or one of those fancy pully biners on the rope with your splice or knot.

Attach the end of your lifeline to the high point side of the biner like in the pic with whatever (as long as your splice or end knot catches on it), these small carabiners do the trick pretty well.

When its time to pull it out just let it rip and pull the end of your lifeline in with all the gear attached.



easy peasy.

Great, close however here's some tips.

Where I have circled in red that "whatever" has to let the knotted rope or a rope with say a retrieval ball attached go through.

The rope then goes through and gets caught by the little clip just to the left. Now the redirect is free, in many instances your lifeline could shake it loose and it would come down to you.

However, assume it doesn't.

Sure you can pull your lifeline back to you but by but by having a short bit of "rope/whatever etc" to that other side of the redirect device you will pull it out and to you as well.

This way you can retrieve the redirect without climbing back to it and maintain your high point.

Thanks for the picture.

hahaha yeah "whatever" is my code for "im lazy so heres the jist and figure the rest out". spot on with the attachment of the end-line to the pully though, i cant imagine it getting very stuck with the ability to whiip the line around and clear obstacles when it slides down the rope. would probably add one in a very branchy tree i guess. word up.

Eric Frei

I know, just we aint the only ones who read this stuff, so it's really necessary to not only dumb it down but make it idiot proof.

Next some dude gets it stuck up in the tree and calls you names because their brain wasn't capable of connecting the dots.

I used to say to a ground guy, when I tell you to put your boots on do I also have to tell you to tie your laces? You'd expect when they drop the trailer on they connect the lights etc too, but mate ... I've even had them come off the towbar coz the latch was still positioned up and luckily the chains were attached but the rear of the ute got a pounding.

I think some of this has to do with finesse or something else that I do not have. Even my throwline will somehow get wedged up if I have so much as a simple overhand knot left in it. Even if the crotch I am pulling it over is smooth it will fall into another one underneath it that isn't and get stuck.
