- Arborist Tree Climbing Basics: Climbing Systems DdRT vs. SRT
These are the basic concepts of modern tree climbing systems that we use. Moving Rope System, better known as DdRT (Doubled Rope) and Stationary Rope System, better known as SRT. Not comprehensive by any means, I just want to give people a framework for learning these systems, so we are all on the same page.

I wish i seen this when i was a beginner ! Great explanation with the scaled down model ! Cheers Treemuggs !
simplicity at its finest! thank you my friend
Sooo helpful for understanding the basic ideas of each technique. The little action figure is hilarious! Thank you!
Thank you for this outstanding video. great explanation and the little scale model really helped see it clearly. thumbs up. subscribed. thank you
Excellent tutorial, one of the best I've seen. Thank you!
awesome video for beginners, explained in really simple and informative way :)
Been watching videos all day on this. The best and easiest to understand of the major differences and their disadvantages and advantages.
Best beginner and intermediate tree climbing and tree work resource on the interwebs by far followed by worksafe bc . Keep up the great work.
Best basics video on youtube. Nicely done!
OH MY GOSH James ! you're in for a surprise, upon return HAHA.. love it ! lucky guy james I had ti learn all what treemugs ( patrick ) is teaching over 10 + years . Im almost 50 next year LOL but SO super excited that knowledge of great tree techniques are here for view so folks get a idea of what is available in the tree care industry .. its amazing how almost daily I meet someone who never heard of SRT or what this mean .. I volunteer sometimes for new inspiring arborist who want to know about basic tree working skills ( just knots n stuff ) Joe
This was awesome. Really helped it “click” in my brain. Thanks for all the great videos you have put out!
Appreciate that! - Patrick
Thank you very much. Simple and informative.
Thanks for the video. Very straightforward and easy to understand.
Thanks for this video. This is perfectly clear to me now. Hope to have my basic equipment soon.
What a great demonstration and clear way to communicate! I nearly did a PhD in Education - This is great work!
thanks for making this video. Such a clear explanation!
Very nice video. Simple and explains concepts well.
Great vidéo 👍 good initiative.
Finally a basic explanation of DRT and SRT ! THANK YOU SO MUCH .
Glad it was helpful! - Patrick
Remarkable demonstration!!!
this is a great video and i greatly appreciate your effort!
Platinum Communications Thank you!
Great helpful explanation, Thanks
Thank you for the informative video!
wow this video was really helpful in understanding the different between double rope and stationary rope techniques.
Thank you! - Patrick
Great demonstration.
Great intro video!
Great info for the beginner (me). Thanks
Superb video. Simple explanations for a learner like me, many thanks.
Glad it was helpful! - Patrick
Lol I like the cool demo at the beggining
This was a great video
Helped a lot!!
Excellent
Go SRT! I climbed MRT for 20+ years. Rope walking rules.
That was great, thanks!
You're welcome! - Patrick
best eli5 of treeclimbing
you are the best thank you
Just doing my part! - Patrick
thanks
Well thought out video bro, ,,,,,,but,,, there is no mechanical advantage as you mentioned on dirt. Mechanical advantage would only apply if the moving part , load had rope advancing through it, .......technically you’re trying to pull the tree fork down on a 2:1 mechanical advantage but the tree is too heavy and you move towards it. The fork “static” is holding double your body weight. Nice vid
Finally, someone who excels at keeping things simple. Lots of videos on these differences but like most people who work at the Apple store, few have the concern, initiative or ability to rely basic concepts to the average Joe. Good job at not proving oneself smarter than the rest of us- even if you really are.
Not smarter, I'm just a tree guy! I'm trying to put out all of the stuff that I wish I could have found online when I started years ago! - Patrick
Great video as usual. One thing for beginning SRT climbers to remember is that with a basal anchor, the load on the crotch or limb that your line is running over will be increased considerably compared to a canopy anchor which is loaded only to your body and gear weight.
A video on how you get the rope up to the top, to begin with, would be really helpful for me. This is a great video on climbing technique, and I've seen a few good ones now, but I still don't know how the rope is initially getting way up there to the top of a tall tree. Could you do a video on getting the rope set up in the tree in preparation for climbing/rigging? I just bought my first house this year and I want to take down my own trees as well as be able to do it for friends/family.
To capture a relatively low crotch, you use a weighted throw bag and some small light slick line. Once the weighted bag is thrown or launched through the fork, it falls back down bringing the small cordage with it. You then tie the slick line to the climbing rope, or a friction saver device, and pull one end while the other end is hauled and fed through the fork. Personally, I've set really high overhead lines with 100lb braided fishing line tied to an arrow with three lug nuts duck taped on the front, but that stuff does tangle up quick if the tree is hairy.
@@truckermike5853 Thank you!
You're welcome, Muggs actually did a more demonstrative video on this that you might like. czcams.com/video/ZbK_a2TsEIw/video.html
KUDO for the explanations ! The only thing I would have you to address is the advantage (dis-) of one over the other in the scenario of... climbing higher when you reached your first canopy point in order to reach a higher fork point.
Is there a big enough difference between the two that makes one significantly better than the other?
Hey bro💯
good schooling
Why use a biner on the srt canopy instead of just pulling the rope through the butterfly?
Would using pulleys and or cambium savers help with redirects using DdRT? I am leaning toward the DdRT with a Hitch Climber setup, but understanding how both systems work is extremely helpful. Thank you.
Just get a rope wrench and you can switch back and forth. I've been climbing for 23 years and I put off switching for way too long. Rope walking rules too. So worth it. Try set once and you'll be sold.
But yeah, you could just use a sling and a beaner and put a redirect anywhere. Even easier with srt.
So in the canopy anchors, you can use both of ropes to climb?
No, 1 side for climbing, the other side for retrieval.... - Patrick
@@TreeMuggs_PatrickM Thank you!
It’s important to note that the carabiner in this video is not to scale
Thanks for this!
Why isn't double rope, non-moving one of the stand-by techniques? As a rock-climber, this was on of the go-to ways to climb a rope.
I'm talking when the rope is draped over a limb/anchor, both ends hang, but then you climb both strands with your friction-hitch around both strands (a sort of hybrid between these two)?
What climbing setup were you using to climb a rope like that? - Patrick
@@TreeMuggs_PatrickM Well, it's been awhile, so to be honest, details are fuzzy... but I remember using a prusik for the harness attachment. Feet varied: I believe either foot wrapping or a sling tied into a klemheist. Perhaps it was too slow
grazie molte . poi c'è da affrontare il discorso di recupero in caso di emergenza. che se la fune è predisposta bene . può essere già utilizzata come recupero di emergenza . grazie molte
would you say that the introduction of SRS to tree work has left the DRS looking 'terminally' ill 😊
Thanks for the video. Can you climb srt with just a prusik and pulley instead of the mechanical stuff? Iv not seen anyone do that. Your model was close to what im talking about, just add a micro pulley.
You need to add a rope wrench above the hitch to climb SRT, otherwise your hitch will just lock up on descent... - Patrick
@@TreeMuggs_PatrickM makes since. Thanks so much for the reply. Stay safe out there.
Which one do u prefer
I climb mostly SRT but I do still use DdRT from time to time... Thanks for watching! - Patrick
Good video. Thanks!
@kurtthearborist
Treemugs your videos are awesome so thanks for your time and expertise! However there is no mechanical advantage with DDRT! A 150# person is still lifting 150# and that doesn’t consider friction at crotch. The weight at the crotch is now 300#. Thanks again!
the only people who would claim that doubled rope doesn't have mechanical advantage are people who have never tried it.... hang a pulley on your anchor point, put your climbing rope through it, and try it out..... you'll be amazed at how much lighter you feel pulling your body weight up. Then try the same thing with a single leg of rope (srt)...... big big difference 👍🙂 - Patrick
2:1 mechanical advantage for sure. Each side takes half the load.
@@TreeMuggs_PatrickMWhen you're at rest on a ddrt, yes, each side takes 1/2 of the load. But in order to ascend 1 foot, you still need to pull 1 foot down on the descending rope. There's no Mechanical Advantage. A 1/2 MA happens when you have an anchoring point at the top and a moving pulley on the load, then you pull UP the rope, so each 1 foot you pull up, the load lifts 1/2 foot. No moving pulley = no MA. In order to ascend solo on a 1/2 MA you'd need to anchor your rope at the canopy, pass it through a moving pulley on you, then pass it through a fixed pulley at the canopy (just to redirect it down), then you can pull it down in order to ascend.
Is there really a mechanical advantage?
I answer my own question; at 3:35 there is no mechanical advantage. The rope looped over the crotch is really a redirect.
“And said, Naked came I out of my mother's womb, and naked shall I return thither: the Lord gave, and the Lord hath taken away; blessed be the name of the Lord.”
