You don’t have an ‘8’ you have a compound 12 to 1. You have a simple 3:1 pulling on a simple 4:1. Compound systems are products of the simple systems. So a simple 3:1 pulling on a simple 4:1 the product is (3x4)= 12.
It looks like you have 3 to 1 ratio ( aka Z rig) pulling 4 to 1 setup. If that is true then you have 12 to 1 mechanical advantage, instead of 8 to 1 ratio.
It's 3:1 x 2 If you tie st the load it is 4:1 The way you did it the 4th pulley is a redirect. Tie at the load and the number will always be even. Tie at the anchor and the number will always be odd. Just by switching where you tie can gain you an extra advantage. Always tied to the load if possible. Other than that very nice gear!
He makes a video on compound pulley systems and don’t even know the correct MA he’s getting. It’s a 3:1 pulling a 4:1 which makes its a 12:1. It a common 3:1 z rig setup, he needs to include the 1 unit of tension coming up from the base pulley to the prussik, that line is still helping pull the load.
It’s not just a CD because it doesn’t terminate at an anchor, but instead adds 2 units of tension to the haul line. Add the 1 unit of tension from block at the base of the pole and you have 3 units pulling on the 4:1. Giving you a TMA of 12:1 at the load.
Right when you put a block with the moving part on the hulking part you multiply the advantage. If they get a book on rigging they will also learn the correct names for the rigs and gear. Then when they go t a store to buy some thing they will get what they need and not dumb looks like their dumbass deserve.
It is a 12:1, that pulley anchored in the middle of the rope gives a 3:1 mechanical advantage (google up "z-rig"). A 3:1 multiplying a 4:1 gives a 12:1.
In SmarterEveryDays video on the compound pulley section he only had 2 units of tension working on the next set of pulleys. In this video there is 3 units of tension being applied to the rope beyond the prusik hitch, therefore you have a 3:1 system working on a 4:1 system creating a 12:1 compound pulley system.
I f-ing love learning new things like this. Very well explained and I liked that you named all the components and gave the weight rating.
Fantastic stuff! I had no idea what was going to happen and now I'm gonna go buy some pulleys so I can play!

This is exactly the kind of info I was looking for.. part numbers and all
I agree with John, it's a 12:1 compound system.

yup it's a 12:1
Absolutely spectacular
THANKSGIVING
10 billion percent it will work
There's a 10 billion percent chance that's a Dr.Stone reference.
It's 3:1 x 2
If you tie st the load it is 4:1
The way you did it the 4th pulley is a redirect. Tie at the load and the number will always be even. Tie at the anchor and the number will always be odd.
Just by switching where you tie can gain you an extra advantage. Always tied to the load if possible.
Other than that very nice gear!
who's after Dr Stone
It would be nice to have links to the items in the description.

so interesting, such a good and well made video!

It looks like an 8:1 with a change of direction, pulling to disadvantage. CDs don't add to the mechanical advantage.
It’s not just a CD because it doesn’t terminate at an anchor, but instead adds 2 units of tension to the haul line. Add the 1 unit of tension from block at the base of the pole and you have 3 units pulling on the 4:1. Giving you a TMA of 12:1 at the load.
10/10. Hands down!
This will help pulling up verizon lines in easements for 200 pair + cables.. i def could use it
Actually that is a 3:1 x 4:1 = 12:1 ratio system, not a 8:1
It's actually a 3:1 pulling on a 4:1, 12:1 compound system not 8:1

zaimponowal mi, juz wiem, ze w szkole na fizyce maszyny proste zaliczyl
That's a 3:1 "Z" rig. That makes it a 12:1 system.
This video blew my mind
there has to to be a simple and short easy explanation
Time to get excited!
Way cool!! Thanks
Didn’t even mention the transformer gin
Muito bom .muito bem elaborado...
Sorry friend but I think your haul-side system is a 3:1, not a 2:1.
Luvit ☮
I count a TMA of 12:1 in this system.
mucho ingenio exelente
I know riggers that couldn't rig a raffle quite a few
Everyone saying it’s a 12:1 system go watch SmarterEveryDay’s video on snatch blocks
It is a 12:1, that pulley anchored in the middle of the rope gives a 3:1 mechanical advantage (google up "z-rig"). A 3:1 multiplying a 4:1 gives a 12:1.

Those quick disconnect push pins, who makes them ?
12:1
Science!
Aonde eu acho esses equipamentos
This is man shit here! :)

You need to math better...
DO YOU EVEN PHYSICS BRUH??? oh wait, you DO physics bruh!!
All that for 5k lol
