How to pass a knot in the rope - IRATA Level 1 Training

- Опубликовано: 2 июн 2024
- In this video you will learn how to pass a knot in the rope when ascending and descending. If we find a damaged spot in the rope we use the Butterfly knot to isolate that damaged spot. That way we can still use the rope safely to go back down or up to exchange the rope for a new one. Or sometimes ropes might just be to short and we need to tie them together. In that case we also need to know how to pass the knots in a rope. I will show you three methods of doing this.
Now for the attentive reader and viewer... What did you notice? I have been leaving little things that could be a point of conversation is a couple of the video's. Did you see??

Thank you so much. I have been struggling in training and you have made it so easy.
Thank you from South Africa 🇿🇦
This is so good to hear!! Thank you!
If you have any questions, follow the links in the about page and DM or email me.👍🏻
Thank you
You're welcome
Great
Thanks!!
Hello Alex, your videos are good. is getting more and more exciting. With you it looks so easy that you convert it to a chest ascender and ID and vice versa. Really exhausting for me, do you have any tips? The best way to position the Petzl ASCENSION is to pull it up with both hands, that's how I do it? Really heavy with one hand.
Glad you like them!
I would have to see you changeover to judge where the improvement may lie. I have just released a new video on the Changeover subject. Besides addressing an issue from the original one, I spent some time on giving some tips on making getting back into the Croll easier. Let me know if this helps 👍🏻
Great to see its done properly, so many short cuts these days on the tube all IRATA yet doing it different?
Thanks😃. Good thing is that there is not one right way. There are countless methods. Some may work for you, some for me. That’s why I like to give multiple option in training if the skill level allows it
is one of the alternate way to put the handascender on the backuprope?
Only if you load it statically and prevent shockloads at all times
Why don't you use your upper ascender to create a second point of attachment to place the Asap under the knot?
Good point. As I have said before there are different methods for everything. For one, an ascender can never be a backup, so there are more considerations then just placing an ascender above the knot. In this video I have the trainees gradually evolve and use new skills progressively. Learning to tie a Butterfly is one of those skills. Clipping into a knot is safer then using an ascender where you want to prevent a shockload at all times.
So for more experience technicians yes, very possible. In training for fresh up and coming L1's not.
Hope that clears it up
Question, so when you pass the knots only using 1 backup on the backup line, you clip the butterfly knot directly to your point A on the harness with a karabiner as this is the fall arrest point.
When you do the second pass on the back up line using an overhand knot in the buttfly knot bite to create a clip in point above the damage section, you clip in the cows tail which is attached to the main front ring on the harness where your decender is cliped on, not the fall arrest ring point A.
Is this a mistake or is it ok, thought the back up should allways be on fall arrest point A?
That is ok. And may also vary a little per region or industry philosophy. According to IRATA we can aid climb with our cowstails as backup. We are essentially doing the same thing here. The reason is that we never climb above FF1 and keep the potential energy as low as possible. Everything with a shockabsorber needs to be connected to an A-point though.
Does that make sense ?
Ah I see so because you are in FF1 or FF0 the fall distance is minimal so a absorber isn't needed, so no need to attach to the "A" point on the harness 👍the front ring is ok.
but if you end up in FF2 waste down for some reason you would need to use an absorber on the "A" point on the harness with your backup because of the fall distance and need the absorber to disappear the forces.
The cowstails are made from dynamic rope and there is some absorption properties. The reason I clip directly to the A point is to minimise fall distance. I would consider it a better practice. Even with a fall arrest device (like the asap) we never want to be in a FF2 situation. @@TheKlaus30
And in all honesty, we use the fall factor in the wrong way.. FF=fall distance/rope length. So when I am in 10 meters of rope and drop 40 cm in a "ff2" asap it is still only FF0,04. And for En 1891 a FF0,3 is acceptable. so having an asap low is actually not as bad as it is made out to be.....
Right, with that oil on the fire it is always better to keep that asap abouve the shoulder and minimise our fall distance..
Thanks for.the info 👍
Sir, i want to get into rope field what would you recommend? Like after doing what course I can work into multiple firm's
Check out the 5000 subscribers video from last fall. About halfway through I speak about this👍🏼
Rope access method is like a boon in modern world for working at typical critical height locations
Yes I think... I am not sure what you are saying
🤔 transfer to another rope i think is one other way
+Eagle pro Tv installations yes, absolutely correct 😃😃
