Great videos, as a woman about to participate in her IRATA level 1, I am finding all your videos very informative. Hope to get a head start on my training courses. Dankjewel!
I love this stuff. The MA of all of the piggy-back systems that you show in your video can easily be duplicated with simple, compound, or complex systems, often with fewer pulleys and rope grabs and with a single rope as opposed to two ropes. For example, I looked at your 19:1 piggy-back system and came up with a less complicated complex system that uses a single rope, 2 rope grabs and 5 pulleys (instead of 6) and produces a MA of 22:1. Can you figure it out?
A is a COMPLEX 5:1 MA B is COMPOUND 4:1 MA C is COMPLEX 5:1 MA D is a COMPLEX 7:1 MA If we talk about "practicality and convenience", A is the most preferred option for people in Public Safety (where i am with) and perhaps with the Rope Access community. It is easier to set-up and do fast resets! SOF plays a very important role with respect to "CONVENIENCE" so to speak. In our community, having an SOF is "GOLD". While your videos are extremely EDUCATIONAL, I think it would be more CLEARER to us your viewers to put this drawings into ACTUAL test to ease out confusions and revisit critical points that you have mentioned. My two cents!.. Keep 'em comin'
Thanks 😃🙏🏼🙏🏼 A and B are correct C and D not 😉 To be honest, B would be the only one I'd ever use. For me none of them are really practical.. Just plan ahead and make a simple 5:1 and limit the resets. No piggyback systems or complex for me. Those are usually for solving a problem that could have been prevented with a little better planning. Or if the situation is different then when the job was planned. Same goes for the SOF. Those are problem solvers. Great to have and often not necessary. This (and past) Grimpday I have heard teams say what a waste it was they carried an Aztek for 3 days and never use it. That said, I always have one in the van and used the Wingman the other day for solving a challenge. But there were 5 other methods possible to, this was the nicest looking one though 😉😂. To your last point, I wanted to keep this whiteboard clear in the beginning to grasp the principles. But in the second video I decided to film an extra bit to show how fast a 9:1 collapses and needs to be reset. Is that what you mean? Put more of those practical examples in? Or more like the video where I measured the Actual MA vs the Ideal MA? Maybe that might have been better, however I am running into a lack of time. This might seem like an 18 minute video, but editing only is about 18 hours, creating all the Vrigger files, extra filming and before you know it something like this takes about 4 to 5 working days to get done not including travel expense to get to the training center etc.. Otherwise I may have done that. And in my mind it looks clearer on whiteboard instead of a tangle of pulleys and ropeclamps. I definetely see what you are saying though and it makes sense. I am working on a at least two more video's. One to explain all the quizzes and one where I put some of the systems into practice to complete the picture. I think something you would have liked on a per video basis right? To get back to the quiz, for C and D, best thing is to right them down and start using the T method where you can see all the ones and twos (or 8's and 10's) travelling through the system. When you have written in out it is easy to add the separate numbers up. If you want the answers, you can find them on the website here: www.theropeaccesschannel.com/what-is-a-complex-pulley-systems-the-t-method-and-mechanical-advantage/ Thank you for your feedback🙏🏼🙏🏼
@@TheRopeAccessChannel Take your time brother. Since the illustrations on the white board were "theoretically well explained" having an actual video on how systems work based on the white board discussions, I think will be even more compelling and easier to understand just like when you explained about the FRICTIONS and PULLEY EFFECIENCY. Over the years I have learnt that a Pulley System acting "directly" on another Pulley System is a COMPLEX MA. Therefore, when you count the MAs on each system you just have to ADD them. Say 3:1 + 2:1 = 5:1 Complex MA. On the other hand, If you have 2 Pulley Systems separately connected to an anchor point that works together pulling a mass, the system shall be called COMPUND MA and this time both MAs on each system shall be multiplied. Say, 5:1 x 2:1 = Compound 10:1 MA. Personally, I think it is much better to start with the practical MAs (2:1, 3:1, 4:1, 5:1, 6:1) should you choose to finally make another video and perhaps highlight why it is SIMPLE, COMPLEX, and COMPOUND. In addition, I also think that the general audience should also be reminded that aside from understanding the basic principles of the MAs rope operators should also be guided with the context of understanding the difference of Theoretical, Ideal, Actual, and other terms when we speak of Mechanical Advantages.
I concur with the others, 5:1, 4:1, 9:1, 19:1. Personally, I'd love more quizes; don't really do IG so would love if they stay on YT, but that's selfish. In particular, more similar to the example at 0:30. I remember seeing an example with one of those buried in a more complicated system, not sure I got it right, real tricky. I know it's all theoretical at this point, but that's personally where I have a lot of fun with this topic. They're like little puzzles for your brain. In any sense, really enjoyed this series. 👍
@@TheRopeAccessChannel Some people get up in the morning and do a crossword to wake their brain up. I like to calculate the MA of pulley systems with my morning coffee. 🤷😆
Great videos! I want to build a cargo lift in my barn to hoist items weighing no more than 450kg up 5m to the next floor. If I assume I want to use a 275kg brake winch (so the handle doesn’t spin out of control when lowering/raising) and want to minimize Input Distance (crank revolutions), what would the pulley setup look like? Based on your educational videos I think a single pulley fastened to the platform, the rope fastened to an upper floor beam with the brake winch up there too is all I need. This would also result in the minimum Input Distance. MA=2 Input Force = 275Kg Output Force=550kg Input Distance=10m Output Distance=5m Can I somehow reduce the Input Distance to reduce the number of hand cranks I’d have to endure? :-)
Not to my knowledge. In order to make it lighter you have make more revolutions. If you design it for less revolutions your input force has to go up. If that makes sense???
5:1 4:1 if you’re only pulling on the SOF’s, which I believe is what the arrow is indicating. 9:1 interesting way to employ your SOF’s 19:1 I think. 5 becomes 10, 4 becomes 8, plus 1… sounds reasonable.
@@TheRopeAccessChannel I’ve used B for knot passes and really liked it. I’m always looking for creative (but practical) ways of using a SOF’s. We have an extra long one (15m fully extended) thats used as a stand-alone kit for raises and lowers with little consequence (acceptable in my world) When the wingman’s arrive I’ll probably use those for standalone kits and shorten up our Aztecs for more traditional uses. (Pitching litters, knot passes, adjustable high points etc.)
@@paulnormandy6247 That would be a very good use of a SOF. And for me, I think it is very important that a tech (or operator depending on your locale) should know how to do it without. Most teams I know that have gotten a wingman have employed that for moving the litter from horizontal to veritcal and back. It is a breeze to release under load. Just this week I used it in the pouring rain lifting 20kg bat homes into place. It worked like a dream.Were other methods possible, yes and this made everything run real smooth!
Thanks this is very interesting, I would be so interested to see an indepth video concerning proper adjustment for a harness for comfort and safety. Petzl podium is in my industrial klimmen shopping cart for when I pass through europe, you think its a good idea for my skinny butt? I find the harness uncomfortable as hell haha.
The very first video I released was on harnesses. The questions you ask are answered there. th-cam.com/video/LsS2kfb90zc/w-d-xo.html But everyone likes their harness adjusted a little bit different. Play around with it. Also body type and harness model/brand need to match as well. If I am working suspended I always use a Podium or other work seat. For me there is no harness where I would enjoy spending more than 15 minutes in working suspended.... If a Podium fits my skinny ass, it should fit yours 😂😂
Hello, I have a question, hoping someone can answer and find the solution? I put a movable pulley on a weight , its decreased the force exerted , so divided are weight by two , and decrease its speed of movement . My question is , how I do to decrease the speed of an object WITHOUT divided are weight , I want to keep the starting weight but only divided its speed . Thank you to you.👍 ( Small pressure , I cannot add extra weight to compensate for its loss ... , ( I want to divide the speed and not the weight ...)
I got tired of no explanations so i tried to understand it and here is my attempt A The black line is a 2:1 pulling on orange ropes left side making it a 2 and its right side is one making orange a 3:1, and it goes to the clamp. Then tension from black is one on one aide and one on the other making it 2 one’s 3 and 2 is five so 5:1 B This kind of ridiculous You have to realize that the black rope end is nonsence. Its just rope automatically being fed out the pully and no evidence for pulling it is given yet its a cd anyway. If you notice the orange rope is clamped to black, the only pully that matters therefore, is obviously orrange. Add the tensions on the inside and you get four C It’’s still four but if you noticed, the black to orange on bottom right is clamped is four just like the first, you label that; then you label the other attachment as four. Since this pulls on black, you have fpur and one side (the left) and one on the right, which is 1,making it five. Then 4&5=9 9:1 D The absolute maddness begins. It was madness before… So the black rope is a 2:1 load on the left. orange rope. The only way is see this working is if the bottom orange to black clamp is 10 and the top is 8 and the other side of top black rope (right) is one. The only way i can think to explain it is to look at the circle thing as botha multiplier and the difference between it and the versions of the other ones. The other circle things were with it being pulled down where this is like in a where its being pulled up but like in a. Where does the tension from c come from? You. Your pulling down In b, the wall eats your input If you think of it now aa physical objects being pulled on, not just multiplying power it makes sences The pullies are being pupled where the walls were canceling extra nonsence and only letting the line energy in. So in D you can not forget that the circle is a power multiplier, and also, the physical wench is being lifted by 2 unts of force like in A, where before you added one, now you add the multiplication. Onsence but you cant forget the lifting of the 2:1 of the black winch on the winch itself making it its gadged multiplier pluss its lift from the 2:1 black winch None of this lifting crap effects the top, only the multiplication factor so it pull 8 times downward, but that rooe is attatched to you so you are asding one cd because now we care about rhe cd in because its complex now
So pn D to clerify, botha ends are 8 from the circle multiplication with 2:1 being multiplied, but 2:1 is physicall pulling on the physical part of the bottom circle thing, so you get because its 2:1 into the 4:1 circle multiplication insanity 2:1 is physically pulling on the wheel. None of the top 8 weel is being pulled on by the weel but the other aise of the rop has one extra input at litterally the end of it added on. So you pull and twice your strength goes into a 4x multiplier device, where 2x your strength as another multiplier device and this powerers an 8x arm in front of yours, but since your pulling on the second arm bellow you, you get to add your doubled strenght as it feeds into the bottom arm, but you can’t double it becauae you aren’t leveragting double to the top end with it, only into it normally as the top end isnt leveraged. You have the other arm pulling the weight directly and your double devoce is physically pulling up on device that is clamped, so its helping, but only that end.

I’ve recently started following a few arborist groups on FB trying to get a better understanding and the rigging and devices you guys use. Do you have any channels or groups that you would recommend?
@@paulnormandy6247 august huneyke(misspelled that for sure) aka monkey beaver, game of trees, guilty of treeson, these would be my top suggestions, if you want to know about the rigging, game of trees just put out a nice video of it, also climbing arborist has some really nice videos.
Right on👍🏼. I get that. To me they are also just for the fun of it. Although I have used B and C to move logs up 30 cm on to a tramway over a creek down hill to where the truck could come get the logs. But I admit not much use in 99,9% of arborist work.
@Paul Normandy I liked Daniel Murphy on YT for his skills with felling trees. Not that much on rigging though, mostly cutting techniques. Last time I watched something of him just be 5 years ago, so maybe that changed…
Great videos and thank you for your efforts to help further my/our skill sets. Do you have another video or link which further explains how to calculate using the T-Method? As I type this I think the answers is z-rig video ? Thanks again
Not yet! In the Z-Rig video I sort of use the same principle. But there is not that much more to it than what I explain here. However, seeing the comments on several platforms made me decide to make a dedicated video for this. That will come soon
@@TheRopeAccessChannel There is lots of information on Static vs Dynamic but almost nothing on Rope Sizes. I live in Ouray Co and search for old mining claims and use Rope Access equipment & techniques but at times when weight is an issue for long hikes I use more traditional climbing equipment, 10mm allows me to somewhat cross over. I assume your audience might be more Rope Access BUT if you could cover both would be great.... In this case SIZE MATTERS Regardless, Thanks for the videos
Thank you for this video ! How, I just purchased vRigger few weeks ago... Sadly without any reduction coupon ! Is it possible to find the Linescale you've created on it ? I would like to create the Petzl Reeve soon, so if it interests you, we could make an exchange ! ;-) Have a good end of year !
Hi Julien, I made the LS3 myself. If you send me an email, I can see if it is possible to send it. Not sure if it is possible, but let’s find out👍🏼 connect@theropeaccesschannel.com
Is there a pulley system that will work where there is a change in direction? Imagine a wall that meets with a corner to another wall that has a 45degree angle. The belts of the pulleys only work in a straight line, but what can we do if we need our pulley machine to pull a load along a structure that has curved surfaces?
Great videos, as a woman about to participate in her IRATA level 1, I am finding all your videos very informative. Hope to get a head start on my training courses. Dankjewel!

👍🏼
A = 5:1
B = 4:1
C = 11:1
D = 21:1
I got tired of no explanations
so i tried to understand it and here is my attempt
A
The black line is a 2:1 pulling on orange ropes left side making it a 2 and its right side is one making orange a 3:1, and it goes to the clamp.
Then tension from black is one on one aide and one on the other making it 2 one’s
3 and 2 is five so 5:1
B
This kind of ridiculous
You have to realize that the black rope end is nonsence. Its just rope automatically being fed out the pully and no evidence for pulling it is given yet its a cd anyway.
If you notice the orange rope is clamped to black, the only pully that matters therefore, is obviously orrange. Add the tensions on the inside and you get four
C
It’’s still four but if you noticed, the black to orange on bottom right is clamped is four just like the first, you label that; then you label the other attachment as four.
Since this pulls on black, you have fpur and one side (the left) and one on the right, which is 1,making it five.
Then 4&5=9
9:1
D
The absolute maddness begins.
It was madness before…
So the black rope is a 2:1 load on the left. orange rope. The only way is see this working is if the bottom orange to black clamp is 10 and the top is 8 and the other side of top black rope (right) is one.
The only way i can think to explain it is to look at the circle thing as botha multiplier and the difference between it and the versions of the other ones.
The other circle things were with it being pulled down where this is like in a where its being pulled up but like in a. Where does the tension from c come from?
You.
Your pulling down
In b, the wall eats your input
If you think of it now aa physical objects being pulled on, not just multiplying power it makes sences
The pullies are being pupled where the walls were canceling extra nonsence and only letting the line energy in.
So in D
you can not forget that the circle is a power multiplier, and also, the physical wench is being lifted by 2 unts of force like in A, where before you added one, now you add the multiplication. Onsence but you cant forget the lifting of the 2:1 of the black winch on the winch itself making it its gadged multiplier pluss its lift from the 2:1 black winch
None of this lifting crap effects the top, only the multiplication factor so it pull 8 times downward, but that rooe is attatched to you so you are asding one cd because now we care about rhe cd in because its complex now
I am feeling A is incorrect though. Maybe a 2:1 on a 2:1 and then that change in direction is added
So pn D to clerify, botha ends are 8 from the circle multiplication with 2:1 being multiplied, but 2:1 is physicall pulling on the physical part of the bottom circle thing, so you get because its 2:1 into the 4:1 circle multiplication insanity 2:1 is physically pulling on the wheel.
None of the top 8 weel is being pulled on by the weel but the other aise of the rop has one extra input at litterally the end of it added on.
So you pull and twice your strength goes into a 4x multiplier device, where 2x your strength as another multiplier device and this powerers an 8x arm in front of yours, but since your pulling on the second arm bellow you, you get to add your doubled strenght as it feeds into the bottom arm, but you can’t double it becauae you aren’t leveragting double to the top end with it, only into it normally as the top end isnt leveraged.
You have the other arm pulling the weight directly and your double devoce is physically pulling up on device that is clamped, so its helping, but only that end.

@@TheRopeAccessChannel There is lots of information on Static vs Dynamic but almost nothing on Rope Sizes. I live in Ouray Co and search for old mining claims and use Rope Access equipment & techniques but at times when weight is an issue for long hikes I use more traditional climbing equipment, 10mm allows me to somewhat cross over. I assume your audience might be more Rope Access BUT if you could cover both would be great.... In this case SIZE MATTERS
Regardless, Thanks for the videos
Thank you for this video !
How, I just purchased vRigger few weeks ago... Sadly without any reduction coupon !
Is it possible to find the Linescale you've created on it ?
I would like to create the Petzl Reeve soon, so if it interests you, we could make an exchange ! ;-)
Have a good end of year !
Hi Julien, I made the LS3 myself. If you send me an email, I can see if it is possible to send it. Not sure if it is possible, but let’s find out👍🏼

Is there a pulley system that will work where there is a change in direction? Imagine a wall that meets with a corner to another wall that has a 45degree angle. The belts of the pulleys only work in a straight line, but what can we do if we need our pulley machine to pull a load along a structure that has curved surfaces?
I’m sorry, I don’t understand what you mean. If you send a drawing maybe that will clear it up
Thanks for the video.
I have a question, where do you get the graphics of the pulleys, carabiners and devices?
That makes me think you didn’t watch the whole video… It is literally in there , I show it exactly 😉.
Thanks!
Thank you Gordon🙏🏻🙏🏻🙏🏻
