Double Line Rope Walker

[ QUOTE ]
Very nice system,

How would you set it up for SRT?

[/ QUOTE ]

It's basically the same really. Except the lengths are tweaked to fit the double line system, you don't use a chest box and there's no over head ascender used. And too, for ease of getting in and out of the system both grabs are non-locking.

In a sinlge line setup everything is geared more fail safe, and has locks,, because you don't have a friction hitch to act as a back up.

Watch the West Coast Get together video and at the end you'll see some single line walker systems being used.
 
Chris,

Be sure to route the bungy through the saddle ring to keep the pull on the pantine in lead with the line. Otherwise it'll get pulled off. Typical of the pantine, but too, one of the features that make it so easy to put on and take off the line. It's just a matter of tweaking it to fit your setup.
 
Thanks for the tips Jer. I'll have to try them out.

Bye the way, I saw the clips of the Working Climber series 2 rigging dvd and it looks like its going to be awesome. Can't wait for it to come out. Will it be this winter through Bailey's?
 
Great stuff G.B .. I tried it this am w/my HC pulley and it worked awesome , the middle hole on the HC i installed a sm biner to keep the bungee cord on line .. Will be using it on some long climb on two palms this coming wk ..

Thanks a lot ,

Later from SO-CAL

Chris, Series Two will be out in a few weeks. Hopefully sooner because I'll be at Providence and would like to have a few at the booth to hand out.

Treebing, before modern cams, grabs and connectors came about all SRT climbing systems were accomplished using common friction hitches and everyday knots. Interestingly a climbers bag of tricks in the old days didn't clink and clank like today.

The advancements in climbing gear has made it possible for a person to climb rope without having to know a single knot. But even still it never hurts a young climber to be versed in the the old ways as well.
 
Well, I didn't expect a casual pop in to the Buzz bar to provide such quality information.

Thanks Jerry - I have been meaning to apply myself to an ergo solution to re-ascending a doubled line. And this looks just the ticket to save me the bother. Thanks again.

Also great to see you in the trees.

Have you tried strapping the second pantin to just below your left knee? Seems it may be less prone to tangles and easier to clip on and off (I'm thinking attach the bungee cord to the pantin with a hook - the bungee stays on the line without probs when limb walking, by clipping the dangling end out the way somewhere?). Just a passing thought.

Best regards

Hi, Palo

Haven't seen you for a while. Thanks for the tips. Mods are applicable to the system, now doubt. It's just a matter of taking the time and working with it.

Glad to see you about.

Jer
 
Great system.

I am wondering if Pantin on the right ankle just takes getting used to using, or if it is always prone to coming unclipped at the wrong time. I use mine some, but can be frustrated by it. Wondering how well the floating one (left side) does for staying on the rope? Maybe I'll try to have both free float. Anybody else tried this?

Can a prussic with minder pulley be used on SRT similarly to how it is used for life-support on foot-locking, except it would not be above the hands/ advanced by the hands?

Anybody use the CMI foot ascender or Kong Duck for this left leg, or in general. I think that I'd rather try something different, as I stated above, I find the Pantin to be somewhat frustrating. I do try to use the proper motion for advancing the Pantin, but it seems a bit unnatural. Maybe just getting used to it.

Thanks for the video!
 
Yes the Pantine does take some getting use to. It helps to look down at it to see, and understand why it un-clips. When you pull your leg back away from the rope when raising your foot the Pantine will dis-engage.

I used the pantine on the bungey side of the rope walker only because it was an extra in my kit. The Petzel basic could work too. Any small rope grab could.

Yep. I've got the CMI right and left foot ascender, but I don't like them for only 2 reasons. The foot strap is adjusted on a toothed cam. The toothed cam causes the webbing strap to fuzz. It fuzzes so much that it can not be practical to use. The second reason is that they are large. Other than that, they never have popped off on me while using them on rope. --As you know, that is critical.

Gerry, Just caught this last night and thought what a boon for an old fat climber. I have all the stuff to set it up and was wondering about the ankle straps. Is this something you had made or is it available from a supplier? Appreciate all your knowledge and contributions.

Today I make my own ankle straps. In the past I bought them through several different outlets. Karst Sports and Inner Mountain Out-fitters. Really though since it's a non-PPE application the strap needn't be any more substantial than the one that comes with the Pantine.

Post a pic of your setup when you get it working.
 
Gerald, I gave your DDRT rope walker a test drive last night. Did a 55' climb on it and it worked great! I found that for me, smaller steps is less tiring and produces significantly less stress on my knees than more aggressive steps. I set it up with a cambiem saver instead of a ring to ring friction saver, so it could be even better with the friction saver.

It's not as gear intense as one might think. I did do one thing differently. I used a Petzl Fixe to tend the friction knot, I know - yet another piece of hardware, but it did something unexpected. It keeps the down rope in an efficient mode even when the feet push the rope outward, like when climbing in free air. Seems to be worth the pulley.
 
BTW, while I am by no means an arborist, I have done lots and lots of experimenting with SRT rope walking. Some systems I've tried are trivially simple - two handled ascenders and a tether(s) from the ascenders to the saddle. I've tried 2:1 setups on the legs and some others. They all have one thing in common - if you can keep your toes against the tree, climbing is almost easy. If you get in free air, you'll tire so quickly trying to support your upper body with your arms that you'll see it just isn't going to work.

I also have tried the Mitchel system which uses a chest harness to support the upper body. That system does work in free air, but it requires a lot of gear, foot loops, tethers, fairly complicated set up and it's not a utopia when it's right, but it is efficient. I don't see that it's very practical for tree work - just too much surplus gear to deal with once you switch to DDRT in the canopy.

But, this configuration Gerald has come up with works. You don't wind up with a lot of surplus gear to deal with, you're already in a DDRT set up, the Pantin kicks off easily when you're ready to free your feet, and the other ascender is high enough to easily disconnect.

Someone mentioned attaching the second ascender to the knee and that is a method used in caving circles and can be seen illustrated in the book, "On Rope". However, I like the bungie configuration Gerald is using, it seems less constrictive to me.

And of course, that's just my 2 cents worth.
