Rapid Ascent Descent System - RADS - IRATA Rope Access Training

[@ShkelqimBejko-dd9xi]

Thank you for Lesson !!!

[@herphermits]

Been using my descender as ascending device since. My particular favorite ia my CAMP Druid & MadRock Safeguard.

[@TheRopeAccessChannel]

Awesome!! A like that safeguard!!

[@340wbymag]

I am new to climbing (recreational tree climbing and saddle hunting) and I like the RAD system. For my purposes it is a wonderful method of climbing.

[@TheRopeAccessChannel]

Awesome! If you have the time and limited gear and not much height to cover it definitely can be a great, easy and safe system. Am i right that with saddle hunting you literally hunt suspended from the rope in trees?

[@340wbymag]

@@TheRopeAccessChannel Not exactly... I do climb with the rope, and I may remain attached to the rope as a backup, but once at hunting height I utilize a small platform to stand on, and a tether to attach myself to the tree. That allows me the freedom to sit in the saddle suspended by the tether, or I can stand on the platform. The tether allows the freedom to move around the tree safely. There are some good videos and a ton of information about it on You Tube. Even if you don't hunt, it is an awesome way to hang out safely in the trees to watch Nature.

@@340wbymag That sounds awesome man!!

[@340wbymag]

@@TheRopeAccessChannel Why is height a big issue with the RAD system? I'd be more than happy to use that system to climb 200+ feet into an old growth tree. I know there are faster methods of climbing, but I am 71 years old and rather enjoy taking my time when I climb.

@@340wbymag I (and most rope techs I know) find that the rads system is good for a short ascent. But doing more than 10 meters it is more efficient to switch to ascenders. Rads seems to be less energy efficient due to the body position. But the upright body position of using ascenders for some people is more exhausting. It requires a bit more technique I think. And body type matters to. If the belly gets bigger the upright position of ascenders gets harder too. In the end in doesn’t matter and every one should use whatever techniques work for them👍🏼

Thanks for this video. How much efficiency do you think you lose by not using a pulley or Rollclip on your change of direction off of the ascender?

[@TheRopeAccessChannel]

If we are only taking friction into account and not the added efficiency of using a biner as a CD for pulling direction than a lot. I will be filming a test soon on that subject although the numbers are already out there. I talk about it in this video a bit : kzbin.info/www/bejne/qXqwd6mclKpoj5o But seeing that translate to numbers on a load cell might make it a lot more visual

[@xavier564]

@@TheRopeAccessChannel Thank you! I would love to see those numbers when you do film that test. Looking forward to it.

Hello! I have been following your channel for quite a bit now. Thanks for the content, we are all grateful So i am wondering if this system is a 2 to 1 or a 3 to 1. My assesor told me if the dead end of the rope is pulled by some one on the ground it is a 2 to 1 but it is a 3 to 1 if the charge is pulling. My acessor says it is a 3 to 1 because if you pull down 20 cm and ascend 10 cm, you actually pulled 30 cm because you ascend as you pulled. What do you think is the correct answer

[@TheRopeAccessChannel]

Now that is a great question and has been a topic for a long time.There are a few ways to skin this cat. One way is what your assessor told you. I like Richard Delaney’s explanation. It is a matter of perspective. If we pull down, we move and the pulley is stationary. At that moment we are suspended in three ropes and pulling down. Effectively a 3:1. If someone would pull the rope from the ground it would be a 2:1 with a CD. They are moving a load (us), we should view it from their position. I remember seeing someone who measured it and I can not remember where that was… Did that help a bit?

@@TheRopeAccessChannel thank you so much

[@TheRopeAccessChannel]

You are welcome 🙏🏻

[@richardleetbluesharmonicac7192]

My frog system is not fluid at all

[@TheRopeAccessChannel]

What is not fluid? Does the rope not slide through the chest ascender?

[@davidtelford4160]

Only good with new ropes, once they've been used a few times or have paint etc on them might as well just do it the normal way

[@TheRopeAccessChannel]

I disagree with that statement. Even with 2 year old ropes used offshore (they feel like 10 year old ropes used by many) this works perfectly fine with this technique. Especially for a short ascent where changing over to descender could be more effort. If your technique is good the RADS system is better than the regular ascent in descender.

[@davidtelford4160]

@@TheRopeAccessChannel oh yer if It was upto about 10 meters max, might as well leave your rig on, but for anything bigger it's just a pain, plus the crab gives a lot of friction. It wasn't a dig by the way, I'm just saying from my experience it's just sometimes easier to change over

[@TheRopeAccessChannel]

@@davidtelford4160 no offense taken my friend, I said it in the video (I think…😂) . Only for a short ascent😉.

To old to be jugging up to far 😂, love the channel by the way keep up the great work
