The "Longhorn Friction Shackle" is effectively a Friction Hitch and Soft Shackle in one, whereby the load bearing portion of the friction hitch can be open and closed to accept the load of an object which cannot be opened, such as a pulley. Related videos:

I hope this comment helps new viewers, as this has been improved indeed, more info available on the channel and for free. I can't imagine how much time and energy was spent, but the progress made deserves the applaud! From the Klemheist and Hedden to the Agile friction hitch, plus the Longhorn with a breakthrough tying process to the Longhorn Agile friction hitch, giving more options for the soft shackle. Superb!

Appreciate the support. The Longhorn Zenith is pretty handy as well. Cheers

@KeepItSwift Месяц назад

@jrbtc Yes, I'm also onto the Longhorn Agile bridge and Blake's tensioner, as soon as I assimilate them, will move on to the others. Definitely won't miss the Longhorn Zenith hitch 👍🏼!

Cool all These new ideas! Really elegant Hitch!

I don’t see you weight with full body weight then not seeing how the pulley advances you up the tree Need demonstration. Very interested. Love the channel

@doncook3584 this video was made shortly afterwards and is on the SRT playlist. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6tTmMyZz9MM.htmlsi=PE6Yh5GgO92pU0lD

Although I am not a climber I could see me climbing with this method as a safety device to be moved up as I progressed for a less experienced climber this could be insurance

@jrbtc 9 месяцев назад

I had a specific use for this hitch and it was demonstrated in the recent video on basic mechanical advantage and SRT Scenario 7. When it comes to redundancy, i prefer to engage that via a 2nd bridge... and it can be integrated with our footloop. See short: ru-vid.com4vZWCDcNYCY?si=BqpxIUElebdwZzo9

@glennreynolds962 10 месяцев назад

Why not girth hitch your pulley to your loop. It seems to be long enough and safer than toggle with tails

@jrbtc 10 месяцев назад

Good question. We can only affix a girth hitch if there's no rope in the pulley and if the loop is big enough. There will always be a rope inside the pulley when rigging a RADS system and we want the loop as small as possible.

@Dan-gs3kg 10 месяцев назад

You could replace the pulley with a metal pulley ring at this point

@jrbtc 10 месяцев назад

Yes but a pulley is much more efficient for transfer of energy than a ring or carabiner

@Dan-gs3kg 10 месяцев назад

@@jrbtc In terms of advantage it's 1.8:1 on a bearing pulley, versus ~ 1.75-1.7:1 on non-bearing pulley like a snatch ring. (The so-called metal pulley ring) Going through a carabiner is about 1.5:1, so not recommended from a standpoint of efficiency, especially when one considers the turn radius. (Perfect advantage is 2:1, for reference) I've not seen numbers on an offset snatch ring, but it's argued that it lowers rope heat/wear on loop since the line doesn't heat nearly as much as it passes. In terms of weight to move the bearing and non-bearing pulleys, it's apparently lower for the non-bearing pulleys. Though this is in terms of ~2# difference, and 5# absolute max. As far as how fast the pulleys move, bearing pulleys free fall, non-bearing pulleys move slower due to the up to double friction of bearing. All of the above as seen in car pulling videos comparing the products, ~1.5t; with the "weight to move" being done with up to ~50# load on the pulley.

@Dan-gs3kg this is fantastic information and I do appreciate it. From my own testing, on a small diameter object, another factor is the stiffness of the rope. Even the sheath design has an effect when using a carabiner. I am working on a non mechanical RAD SRT system that is smooth enough that i can climb using only one arm. A pulley in this location is helping.
