  • @2:00-2:30 You SOUND like Nick Swardson from Pretend Time in an episode about a sexy voice radio man talking about a disaster that was happening on a highway HAHA good job mate

  • good lad

  • Comment removed

  • For those of us aspiring to be monkeys!

  • to make a point regarding safety, rules dictate that screw lock carabiners aren't to be used, triple-lockers should be used especially where ropes rub and cause screw locks to unlock....two cents!

  • @Spartreeman A good point for Arborists, but there aren't any rules for Recreational tree climbing, except possibly the GOTC recommendations to AEE. For arborists, triple lockers are a very good idea, as they are busy with other things. Triple lockers are also nice for recreational purposes, but plain old screw gates are sufficient. Where we cannot keep an eye on the lockers, we use two screw gates. Also, we girth hitch our ascenders so there is no need for a carabiner at that point.

  • @CornellTreeClimbing where do you hold classes at?

  • @Zombiemage2 We hold classes locally in Ithaca on our land, the University's land, and some city properties every so often. We hold expedition courses in Costa Rica and in California. We also travel to offer lessons to groups in their own groves.

  • Hi at 6.04 What is that knot on the left hand side the orange one as i would like to try this system Could it always work on a plussiks and a blacks hitch I was to use that insted of the orange knot

    Thanks

  • @Gauge1channel The knot on the left in the orange rope at 6.04 is a Blake's Hitch. You can use any number of friction hitches in place of the Blake's Hitch, although some are better than others. A prussik knot, for example, could be used in place of the orange rope, but it would be slower going up and downright irritating going down.

  • @CornellTreeClimbing Thanks

    I thought it was a blakes hitch but wernt to sure from that angle I tried the set up this year at the APF show in the uk and decided it wernt for me at the time But know ive seen it again im going to give it ago

    Thanks again and i love all your videos ive been having a good look threw them all and pick up a few things

  • Well done videos... learned some great knots! :-)

  • Hi, Thanks for these videos.  I am a beginning tree climber and it is really great to see all of these techniques demonstrated. I disagree with some of the other posts in this forum who complain about the demonstration of unsafe/unrecommended techniques. It is important to know the DOS as well as the DO NOTS and I believe doing so actually creates greater safety awareness.

    Keep up the good work!

  • @zeynoleary Thanks for the kind words! I have confidence that our methods are safe. We've had an excellent safety record to this point. No climbing-related injuries at all in countless lessons, both domestically and internationally.

  • The best tree climbing videos out there! Thank you.

    One question on this video, right before you talk about how to tie the Blake's hitch he ties into his harness with a knot that i would like to use, what is it called and can you talk about how to tie it?

    thanks again

  • @TheLivingston2 Thanks! The knot that David tied in with on the red rope was a clove hitch. The advantage of the clove hitch is that it is easily adjustable. This is pretty handy as the length of the connection between your harness and the friction knot affects your efficiency. In this mode the clove hitch isn't likely to slip too much, but you could also use a figure eight on a bight if you experienced that problem.

  • Kudos for posting this video! I looked, this up because 35 years ago someone had shown me how to make some of these knots for tree climbing , and over the years I have forgotton them. It was a blast from the past to have seen these again! If you look at every tree climber site or mountian climbing site there is always someone who knows how to do it better or safer, and does'nt understand everyone is not using it as a training video. Why don't all of you go make a training video!!!! THANK YOU!!

  • Hi. sorry but you are promoting unsafe techniques.

    Unsecured footlocking, secured footlocking with a short prussik, don't you know that you should never hold above the friction hitch. You don't even back-up your ascenders. Many falls have resulted from these bad practices.

    Please don't teach tree climbing or at least get some training yourselves from a qualified professional.

    Hope you don't mind but I may use this vid and some of your others for training purposes "spot the bad practice".

  • @totaratree99 Actually, we just presented unsecured footlocking as a curiosity piece. We don't teach that in our courses. We also don't teach secured foot locking, although with this type of static rope and prussik it is very hard to knock it down. I think I should have said that more explicitly in the video - I think I might have said something like "not very safe".

  • Hi. nice vids. However you are promoting some unsafe pratices (and I'm only halfway through this vid).

    Unsecured footlocking - my goodness, ididn't want to watch. Then the secured footlock the prussik is so short! Do you not know that a climber should never put his/her hands above the prussik. Then your ascenders are not backed up.

    Many falls have occured through using the above methods.

    Please stick to mountain biking and cross country skiing!

  • After looking at Your vid, I got some new ideas, how to improove my method, although it is still different from Yours.

    BTW: I cannot imagine, how You are able to place a protection, without climbing the tree first? Hmmm. I'll think about it.

  • Hi CornellTreeClimbing, thanks for Your answer!

    This gives me some work to do with two dictionaries: english and knots :-D

    If I get it right, You do not use techniques, where the rope does NOT slide over the brach? It's always sliding, but You protect the tree?

    I climbed my first tree two days ago and it took me ages, but I am using a "non-sliding" rope.

  • I am surprised, that You do not seem to care much about the branches: the rope is not in static contact to the tree, but it is sliding over it und thus damaging it (oh, I just saw in the film, that You are even showing this).

    Do You feel, that small damage is acceptable? I think not.

    What technique do You use, if You want no sliding of the rope over the branch? I hope, I made understandable, what I mean.

    Thanks.

  • @wollmamaguckn Good observation. We use a total of four branch protection methods: the conduit style friction saver, the leather style friction saver, false crotches or various types and cloth padding. We intended to do another video series on Minimum Impact, but haven't gotten around to it yet. It is very very important, especially on thin barked trees. That was the point we were making at the end of this video.

  • basejump I hate to break the news to you, but the majority of trees in this world are climbed by folks in flip flops.  I use to think I could climb a tree fairly well... then I paid a kid ($0.10) to get me a coconut and marveled at his unaided technique at literally running up the tree.

  • Me again i just wanted to ask is the blakes hitch technique with the two split tails possible with spliced eyes? and whats an ideal length for split tails (as i am ordering them cut to length)?

  • Never put a hand above the friction hitch. In competitions you'll get DQ and in a panic situtation you can grapbon to the hitch from above and make it release and go DOWN.

  • @trepaarboles I'd go a bit farther and say that the single prussik method with footlocking although very fast, is not one we recommend for recreational tree climbing. We always climb with more than one connection to the rope. In that case, where you put your hands is irrelevant. Even with one prussik, our 5mm cord on a static line is very difficult to knock down.

  • could you tell me whats a good low price type of rope to get for a beginner.. bearing in mind i will be using these drt methods.

    Should sliptails be made from the same type of rope and have the same diameter?

  • @danthelambboy Sure. There are many arborist climbing ropes available. There are differences and everyone has their favorite, of course. We use New England Ropes Safety Blue for our climbing lines, and Safety Blue Hi-Vee (the orange and white mix) for the split tails.

  • assuming you dont have a knot at the top of the climb (ie the rope is just slung over a branch) what safegaurds do you use in case one of the ascender cams fails during the double rope technique? Any way to incorporate the full circle rig or do you have to just tie both ends to the base of the tree

    I've read of accidents in which twigs jammed up a cam and down they went..

  • @uyuni123 We really don't use the twin ascender method at all. The weakness is as you point out - There is no backup for a single cam failure. You can tie the ends of the rope off, but then you've eliminated the possibility of using the doubled rope mode. Another problem is that the ends of the rope can easily become different lengths, creating the possibility of rappelling off the end of the rope!

  • thank toy for the info!! Now I can be a Greatest Mexican Tree Trimmer!! LMAo!

  • you great

  • Very Informative video. Looking forward to more of your postings. As a working climber in the tree industry it's good to see a variety of techniques used and taught by others.

    Keep up the good work!

  • c'est la technique de chez Hévéa France cela fait presque 10 ans que cela existe mais en France ils mettent fausse-fourche du sol (abime pas l'arbre) et la main au dessu du noeud (malade même si le noeud bloque bien ) de plus un noeud sur deux brins sans contre assurer faudrait pas dans la montée se tromper et ne prendre qu'un brin !! descendrais bien vite. ce n'est pas une critique mais un constat entre grimpeur tu sais bien la communication est indispensable à bientôt.

  • good video and devices. thanks

  • maybe you should start trying the shunt out, i like it over using *Prusik loops*. i think its safer too, but you only climbing trees, so the shunt might not suit you.

  • Comment removed

  • well im a rock climbing, and i never thought of doing this before. looks fun:) going give it a try soon! but on the rocks:P

  • im talking about the very first thing he does

  • Sorry, but it's really bad what you showing in this video, no cambium saver, one hand above the prussik knot, not locking rope and no back up on the petzl ascender (really dangerous), doesn't matter if you make different and safer during the working days, but looking at this this video many beginners can think that this is right!!!!if you wanna show something like this you MUST be perfect and professional, you're giving a bad message, sorry

  • We do use cambium saving devices - see our other videos. Part of the point of this video was to show how easy it is to damage a tree.  We'll post another video on minimum impact. As for the hand above the prussik issue, our 5 or 6mm prussiks lock up so? hard on the climbing rope that if would be very difficult to knock it down accidentally. In any case, we don't use the single prussik or doubled ascenders method in class because, as you point out, there is only one connection to the rope.

  • c'est vraiment dommage d'abimer un arbre juste pour montrer ce qu'on ne doit pas faire?? (désinformation) montrer tout de suite la bonne technique. bien à vous et que vive les arbres !!

  • @CornellTreeClimbing you mugs. dont climb trees. unless you know what you are doing.you teach bad methods. you have no respect fof trees and peoples safety. you give arborists a bad name. no one climbes trees in sandles :-D use aduqiet footwear

  • @basejump911 Wow - That's quite an indictment. As I've said many times before, we are not Arborists. We don't cut / trim / anything or climb trees with obvious hazards. In years of climbing we have had no foot related incidents or injuries. If you would like to discuss our methods further, I suggest you contact us directly.

  • Thanks for the video. It is an aid that helps to flesh out my book learning.

  • That's really cool that Cornell teaches tree climbing. I am surprised however that a kid smart enough to get into Cornell would want to spend his/her life in a tree with a chainsaw!

  • nice climbing techniques. some were new to me

  • I really must criticize you for not using cambium savers. These are standard equipment for arborists and rec climbers and are available in a variety of types. See the offerings from Sherrill and New Tribe.

  • We do use cambuim savers. Though we did not feature them in this video, we have several mechanisms for limiting tree impact. Perhaps we will compile them all under the title of "minimum impact."

  • I just think you should be using them consistently in all videos. Since you are associated with Cornell University I have to hold you to a high standard.

  • Comment removed

  • Your climber is putting his hand about the prussick that is a BIG NO NO - also to desend - You use a figure eight. Where is the climbers helmet? where is your friction save on that Sycamore - that POOR tree did you burn it?

    Why are you all body thusting?

    I love the UNI - thanks morgan also nice keens

  • We generally don't use a single prussik secured foot locking method - demo. I don't think we would call grabbing the prussik a "big no-no". Anytime one down-ascends with a prussik it will be necessary to grab it, for example. We generally use a tube style descending device in preference to a figure eight, as that style is less prone to inverting into a girth hitch. We did damage the sycamore - disappointing, but we felt like we needed to show how easy it is to cause that damage.

  • Great video.
