Great stuff guys - thanks for all the effort - in return I time stamped all the wonderful info - hope its useful for learners
0.:48 Overview of Webinar - to talk about moving rope techinques - in particular parts of the Hitch Climbers Guide to the Canopy www.treemagineers.com/pdf/hitch_climbers_guide.pdf
2:58 Hitch Climber Pulley 4:45 Basic Hitch Climber (CE climb) set up
• uses DMM Duralock Ultra O's (benefits and how to use 1:41:50)
• Tying CE climb type hitch (Valdotain 4 over 4) 5:39 (clarifying which hole to tie in on Hitch Climber Pulley, later at 22:17)
• Minimizing twist in line using hitch 8:40 (countering twist in use 1:09:35, 1:41:41, 2:17:10)
• Adding a grommet to the carabiner to stop hitch eye slide 16:15
• Carabiner nose orientation is upwards for quicker clipping 16:40
• OVERVIEW of the force presentation 17:38
(redirects and deflected ropes, loads on multiple tie in points, basic lanyard use and attachment, ‘Add-in’ Prusik 1:10:09, V rig (or M method) 1:43:15 , Add-in Prussik with V Rig)
• Load measurement 19:50
Redirect angle force variation
• 90 degree redirect -> 141% load (peak force) on anchor point 20:20 & 24:57
• 120 degrees - the so called ‘magic’ or ‘critical angle’ -> i.e. theoretical optimal angle to get equal peak
force to load (tension) i.e.100 units tension = 100 units peak force (assuming no friction) 25:35
• Angle of peak force on anchor points (bisect) 27:28
Deflexion forces
• 90 degree deflexion -> reduced to 70% on each anchor point (½ of redirect angle force) 30:30
• 120 degree deflexion -> equal force to weight on anchor ps. 34:00
• 170 degree deflexion -> increases to ~ 6 x the suspended weight 35:57
Demos of sound and unsound loading from redirects and deflection forces
• 90 degrees redirection 40:50
• 120 degrees deflection 45:00
• Intro to subject matter to be discussed on the tree over next few hours (Multi anchor point basics, Add-in prusiks, V Rigs, Add-in prusiks with V Rig) 49:55
• ABCD’s to consider before climbing (Anchor point, Belay, Connections, Decent) 50:28
• SRT ascent 51:30
Lanyard use
• Tying on with lanyard with pulley saver 54:02 & 1:01:50, CE lanyard make up 1:02:55 (distal hitch with Pinto pulley)
• Use of locking vault 54:25
• Use of lanyard forward and side D’s 55:45
• Use of swivel (getting even wear) 1:0:22
Basic way to tie-in with 2 anchor points 1:01:20 - options are lanyard or second system or making use of the end of tie-in line
Using of a multi sling ring to make built-in slack tender 1:04:47
Add-in Prusik using a thimble prusik to create O Rig for easier ascent 1:10:00
• Minimizing wear points on swivel 1:15:45
• Materials used in friction hitch cords (prusiks: aramid for heat resistance & polyester for grip) and bridges (dyneema & polyester)1:17:35
• caution with using multi sling as hitch if moving around a lot as the polyester melts easily 1:19:30
• Climbing to set up another anchor point on another lead 1:23:45
• Virtues of Add-in prusik and alternative lanyard compared to double ended lanyard, 2nd lanyard or foot-lock prusik 1:28:05
• Adding extra prusik to enable disconnecting eye splice and gathering of the end of the line to effectively make another lanyard [using 1.3m multi-sling to create 6 cord (bidirectional) prusik]. 1:30:24
• Another use of Add-in prusik - using end of line with throw bag to reach higher crotch 1:35:40
• Virtues of the 4 action gate anit-rollock Duralock carabiners 1:41:53
• V Rig (or M Method). History 1:43:10
• Limb walking on V Rig
• setting up anchor point for V Rig with pulley saver with Pinto pulley 1:58:45
• setting up V Rig eye splice thru anchor point 1:59:25
• finishing V Rig by adding Hitch Climber Pulley ‘RAPIDE’ (with roller bearings) to reduce friction when using with
Add-in prusik. 2:0:30
• Trolley crossing by hand-over-hand in V Rig 2:11:15
• Retrieval of anchor point pulley saver and undoing of V Rig 2:15:50
• Using Add-in prusik for a redirect 2:18:10
• Setting up V Rig again with Add-in prusik and Hitch Climber Pulley 2:22:22
• Traverse using the Add-in prusik as a progress capture i.e. to hold position 2:25:30
• Changing traverse direction by switching the Add-in prusik to the other side of the Hitch Climber RAPIDE
• Using Add-in prusik to retrieve the anchor 2:30:45
• Counter balance rescue 2:38:15
• creating stitch plate i.e. friction to deal with added weight - add Ultra O into forward D (using bite of rope thru 40mm anchor ring clipped to carabiner) 2:42:38
• Materials used in friction hitch cords (prusiks: aramid for heat resistance and polyester for grip) and bridges (dyneema & polyester 1:17:35
oubled Rope Techniques
This is one of the 1st videos I watched while teaching myself to climb, 4 years ago. I've come a long way since then. Glad I started watching all these skilled Arborist😁
Enjoyed it! Taylor, it was a great refresher, and you came through well, despite the video/audio problems. Not being able to see detail on the setups, I went back to your Multisling videos - which helped my understanding of the details. Nick, this is a great forum for TreeStuff.... If better audio/video/broadband equipment is available, please invest.... Looking forward to the next one... maybe Mark Chisholm/Stihl?
Now that's a versatile pulley! Looks like a four pack with prussiks and caribiners will do nicely...Thanks for the rope, spurs, saddle, hitch cord, spur guards, stickers, and safety glasses. Your service was tops!
Thanks so much for this video, really good stuff
You would think treestuff could afford better av equipment. Everytime I watch one of these the videos are extremely choppy and resolution is horrible
I am new to this but I really enjoy your instructions and the information you all give along with the laughter you give. Being I am new I an learning and at the same time I don’t know nearly what you are talking about. Any suggestion for books to read would be greatly appreciated. I live in Florida and there is just not much information to work with. I also like you not using foul language.
Tree climber companion, all kinds of good information easy to read and all the basic knots
Thank you Taylor! Wonderful info
Taylor, could you go into your ascent system, looked very simple and effective. Thanks.
Nice technic at 1:37:00 seems to be useful. Thanks for sharing!
I've watched this a few times, definitely some great bits, I'd love to go to hdqtrs but being in so cal, that's a bit of a trek for a single father...
Thank you for paying respect to the veterans on their day! Very classy paying respect unlike some of the low class overpaid whiners on tv every Sunday!
Very good information...poor Quality video and Audio ...thank you for your time !!!
hello its paiige here i just was ging t enter the contest if its still running the other letters are CDEFIKNPQRSTUV is the other letters in the english alphabet
what is the size and length of the prusik cord
Looks like 8mm hitchcord
What are kilo newton's.?
Oh cool. Thank you for the video.
@ 1:30:00 how do you tie up your Prussic when it’s not in use?
Good rig thank you for all that info
Thanks for all of this😃
Taylor glad you saved nick hahaaa👍👍👍thanks treestuff.com
The topic of this video is really interesting. Yet the sound is terrible and causes an headache. Please let someone redo this video with proper sound. Maybe the image quality can be improved too. And try to get a nice flow in the video for the viewer too. A bit less unnecessary nonsens like viewer questions and weird competitions and more focus on what we are teaching the arborists. They must learn and should not fall down because of bad sound, bad image quality and disturbing viewer questions and competitions.
Success!
Thanks for the feedback. This was our first time filming outdoors when we shot this 5 years ago.
El sonido es muy malo pero la información muy buena
At the 6m mark. Sorry Taylor Hamel, I love you, but according to Richard Mumford, that's actually 3 wraps. ruclips.net/video/9jEG8-KjDHY/видео.html
Damn I want that green one ☝️ gimme gimmme gimme 👐
Good content, bad video and audio quality -
When your trying to learn something the game show bs is just a distraction the rest was great thanks
I didn't know Henry Rollins climbed trees
@1:33:00 lmao! 😂😂🔥🔥🔥🔥💯💯AF!
Just so as video by like me
Wow you are the slowest tree climber i seen so far
Thanks lightning
Yeah that’s cool dude I’m bout wise to ow I to oroo but open up itit and and opuooooooououooooooooooooooooooooooooiooioo
eno
Hey I have an idea on how to increase sales, lets hire someone with the gift of gab to get into a tree and show off all the products we have for sale. And maybe the climbers who feel like they have to have all the pretty toys will forget about the basics of production tree climbing will put all their hard earned money into our bank account in exchange for all our overpriced products. SHAZAM!!
are you still salty?
Dack lmao
He's a DMM rep? I was wondering that while watching TBH and it crossed my mind he's likely affiliated (if not outright owning) dmm, but - and I'm just learning so don't flay me here - but I guess I thought that DMM, Petzl etc were seen as good and "pushing the industry", that's the thinking I see so much, I'm new so I'm erring on the side of caution and only getting name-brand, rated gear but it has gone through my mind "why on earth should a little hitch climber cost this much it's just a lil chunk of metal?"....Interested in your thoughts on this as your reply leads me to think you kinda shun dmm in-general and that's a new POV to me that I'd love to hear expounded upon (I own nothing by dmm, but in placing my first order their hitch-climber or the Pinto were going to be my go-to for MRS - still unsure if I'm going that route or skipping it to get ascenders and do SRS)
Yes, Taylor is a rep...Original comment referred to DMM being overpriced... Are there less expensive options, yes. In DMM's case, you get what you pay for , innovation wise ,build , design and material quality... Not to mention, Taylor is a nice, down to earth guy.
