TRT

[treebing]

One difference with TRT and Dsrt is that with TRT if you cut any part of any line, you fall. so there is no redundancy built in to the system.

@treebing; So, Kevin, apologies if you've posted this before elsewhere, but I was wondering if you might be able to post an image in this thread of your setup using two Rope Runners? It sounds like you've figured out a way to fasten them together somehow, which is something I'd like to see.

As to the lack of redundancy built into the system, thanks for foot-stomping that piece of information for those folks reading this thread that might not have realized that fact.

I got excited by JohnnyPro's very first video of this technique, because of the obvious ability to adjust the tie-in point to anywhere along an axis, but I did realize that it all amounted to just one long rope.

I guess we need another acronym. DTSRT, maybe? Doubled Twin Stationary Rope Technique? This would require a minimum of two Rope Runners and four ropes, but to do it optimally, you would need four Rope Runners and four ropes. This would provide the redundancy needed to be able to avoid lanyarding in for every cut, plus it would provide maximum work positioning possibilities.

A lot of work to set up, but it might be fun to play with in a non-production setting. No one would be more likely to have access to four Rope Runners than the man who invented it himself. Maybe you could give it a go, during a time of no work pressure?

Thanks in advance for any responses you choose to provide, Kevin.

Eric, please make me one of your pulleys, it looks a c e !!

Hai!!!

@oceans said: " Slack tending takes care, because if the rope twists above the Bird...
...So when this happens, do you just have to stop in your tracks for a minute and work the twist out of the rope by sending it down through the Rope Runner and out of the bottom?

With your new flat pulley, does this cease to happen at all, or do you still find yourself getting twists on the way up?

I have to stop in my tracks because of the tolerance between the body and lower arm Bollard on my particular Runner setup. Because of my weight, I have to flip the lower arms around backwards to make a tighter rope channel. In stock form, it won't hold my weight without making the Bird feel too hard to release. I like a soft, modulated Bird feel.

Due to this narrow channel, a twist will not pass. It sure might in stock form, but I'll never have that luxury. It's just become something I'm aware of and manage.

The Pulley doesn't affect going up, just down. Fair question though with such an intricate device.

I'm on it!

no they are not fastened together, just like my dsrt setup. two bridges two swivels. they both clip to my niteize s clips on my didier chest harness. you just operate both at the same time unless you use one and not the other which moves the overhead unifying connection of the TRT setup in space

 

[oceans]

That sounds tempting

I was so into DSRT at the time Jonny introduced this with the Runner. I was concerned with the forces at the tie in points when "floating" the suspension points between two branch unions. I also couldn't get the Runner to hold my weight. After climbing with Paul in Japan, he got me real interested, especially with his anchoring. Once I got the Runner to hold my weight, I ran with it for a while and it has now become more of a go-to when it happens to work with particular tree types and work orders. I did have to dedicate a Runner to this system, though. It's a good tool to have in the bag.

Hold on, you are putting trunk anchor dangers into the mix here, Kevin. The chances of cutting a rope between the belay point and a top anchor are nil, unless you are a possessed chainsaw wealding maniac. TRT, my TRT anyway, works with a top anchor and this is crucial to get the most freedom.

What about all the climbers that have cut themselves out of trees while on DdRT?

 

[SoftBankHawks]

What about them? Surely you must tell me something?

 

[DSMc]

They were not base or trunk ties.

 

[SoftBankHawks]

...and?

 

[DSMc]

Their line was right in front of their face and still it was cut.

 

[oceans]

@SoftBankHawks , your sheave is ready for flight, good sir.

 

[TimBr]

Well, that was quick!

Any photos of the preferred canopy anchor with TRT set thanks

I think we all hear what you're saying Dave but one can't account for stoopid. Lol!
I think the assumption is that we are competent and the chat is about the rope technique and systems, not chainsaw technique.
Human history has shown that no matter how much safety, backup and redundancy one incorporates, some people will still be negligent.

Yeah, it occurs to me that when a climber like @oceans provides such a strong statement of endorsement for a setup or technique, that the man behind the technique may be on the leading edge of development of a climbing style few have ever seen before.

@SoftBankHawks, maybe once you feel you've got most of the kinks worked out of your climbing system, you could make a video and share your ideas with the whole climbing community.

If you feel you've worked too hard and too long to give the information away for free, maybe you could could consult with @Pfanner man to learn how to set things up to allow climbers to pay for access to the videos.

Free or for payment, I think you'll be able to reach and teach a vastly larger number of people through the internet than by in-person instruction. Not many folks can swing the expense of travel to Japan, as much fun as that might be.

Thanks for listening, and I hope my words cause no offense, because none is intended.

Hmm....I would hope that is true. Kevin was merely pointing out the advantage of two independent systems when utilising two lines and I found Paul's comment that the likelihood of cutting the line in a TRT system as " nil " to be more than a little inaccurate.

I use the much-maligned base anchor on virtually every climb. All systems will have strong and weak points. Safety and efficiency comes from knowing how to take advantage of the former while accurately assessing and mitigating the latter.
