Thank you! This is the best video yet on rigging twin wheel pulleys. Every other one wants to show me theory and use drawings or separate pulleys in tandem. Bravo! Ten thumbs up!
After the last passthrough, you need to attach the rope to the knot (or to a hook/loop you fashion) at the top of the first pulley instead. The way you did it, you are only using three pulley wheels instead of four.
Thanks for the video! However, if I'm not mistaken, the setup that you demonstrate would decrease your load by 66%, not 50%, since you're distributing the weight among 3 cords. So your 60 kg stone effectively becomes 20 kg. Furthermore, if, instead of tying off the knot on the bottom pulley (which is effectively utilizing only half of that pulley), you brought it back up and secured it to the support rod to which your upper pulley is attached, you'd be using FOUR cords to support the load, and your 60 kg stone would now be 15 kg!
Thank you for the feedback you are right. At least people can see how it's rigged and what you need to build it. Thank again fir your valuable feedback.
I didn't even know about Alan Rickman properly before you mentioned it . I blush ☺️ I have spoken to thousands of people in person tens of thousands not once in my memory did somebody , here in England point that out. So whilst you think you have no great voice you certainly have a good warband vocal memory. Voice qualities are so unique and I am sure you are being modest with your words about yours.🤩
Sorry, Felix, you got it wrong. You are only using three of the four pulleys so it's a three fall tackle, not a four fall tackle. 3:1 advantage, not 4:1. Because those washing line pulleys only reeve one side - the side with the eye - you need to contrive another anchor for the rope. You could run the rope up to the main suspension. It'll work just as well. Another point of order - you don't have to do knots tight, you just have to do them right. Without going back and watching like a hawk, I don't think the knots were up to much, either. The thing about a good knot is; you can untie it again, quite easily. A multiplicity of "easy" thumb knots (or Overhand knots) can be a knightmare to untie after any load has been applied. Sorry to be a grouch, but we Scout Leaders have standards.
I dont call it a four fold , i call it a double pulley but you are right about using the fourth roller, its an honest mistake if mine . I paid no attention to knots at all . If i had i would have used slip knots. I am not a knot nerd but as a builder i had to user 3 or four different types of knots suggessfully for decades.
@@felixbrunner5707 Yeah, I've found the same. 3 - 4 gets you just about everywhere you need to go, other than a highly specialized field, obviously. This is a really helpful video, thanks.
Your calculations are wrong. If you're using 3 ropes, your advantage is 3:1, not 2:1. Lifting a 60kg load will require only 20kg of force, not 30. It's a pretty simple formula.
thank you ! if i had any hair left i would have pulled it all out by now. video is easy to understand and works :) !
Glad to be of assistance x

Ok ill try that , did what was shown to me and what came natural.
@@felixbrunner5707 cool, glad to help. With some pulleys there is a bar below the wheel which you can use to attach the rope.
I had the same view... one is jobless now
Thanks for the video pretty helpful. I'm going to be building a bicycle storage system using pulleys has helped as a demonstration.
Thank you, just the rig I need for light to moderate duty in the garage!

You sound so much like Alan Rickman! What a cool voice. I envy you. Unfortunately, I sound like a dork. Upvoted!

The system you set up there would reduce a 60kg load to 20kg. 3 ropes between pulleys = 1/3 weight.
That is assuming there is no friction , so in theory possible in practice it's closer to half.
@@felixbrunner5707 good point
The internet's most popular pulley video
Thank you
Thank you for this!
Thankyou so so much!
thank you. got it.
nice thanks
Thank you
By increasing the number of pulley,the length of the rope used also increases.....is this correct or not..........pls do reply...🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼
Yes ....that's seems to follow naturally
@@felixbrunner5707 👍ok..thnku😊
You need to think about how hi you want to pull then multiply the hight by how many pulleys you have at your disposal.

Interesting
Triple pooly ko kitne MM ka rope chahiye??
This guy loves pulleys, hates laptops
The lap top is still in use, it has a strong lid and was perfect for colour contrast with the white rope. 😊
@matt ..... Well done for spotting that bone 😊
What is the size of the pully?
The rollers are about 6 cm in diameter

what are you doing on dry land??!!
Moved there 7 years ago , space for my upencoming teenagers being a main issue.
2:50 Sure it is 60 to 30??? Not 15???
Not it halves the weight from 60 to 30 it's A physical law.
@@felixbrunner5707 Thanks. Does a fiddle-block, with two-pulleys also give a 2-to-1 advantage, like your above demo ???
Oh my f****** god if it wasn't for this video I guarantee I was doing this s*** wrong
you lose one
Thread it through and you win one 🙂
