Reeving Tackle Blocks

Reeving two triple sheave pulleys for mechanical advantage.

Really appreciate this ! Borrowed the 6 pulley block and tackle, but had no way to figure out how to use it. Now I'm ready to go lowering 5 - 120 pound blocks from an old chimney down through the living room ceiling. Thanks again.

[denniscurless]

Done correctly, learned to do it this way and used at my job for the next 41 years.

[rowgler]

Thank you, good to know. It's better when they run smoothly.

we used to pull 3 to 5 tons of ship offshore by using this method. Big ships were pulled offshore by using another method manually. It reduces manpower to pull heavy objects.

I tried to memorialize this in words for quick reference: Revisions Welcome:
Left Block, Axle Vertical, Becket
Right Block, Axle horizontal

[Inboard is near, Outboard is Away]


Thread Tag End in following sequence:
1 Left Block: Outboard Middle-Inboard Middle

2 Right Block: Inboard Low-Inboard High
3 Left Block: Inboard Top-Outboard Top
4 Right Block: Outboard High-Outboard Low
5 Left Block: Outboard Bottom-Inboard Bottom
6 Right Block: Center Low-Center High
7 Becket


Great Reel. Thanks!

Ok, so this is a force multiplier correct ? If so how do you calculate the amount of pull before the rope fails. N other words, can’t he rated rope strength be multiplied by the amount of pulley sleeves ? Anyone ?

[erikaslt]

Becket is basically a clove around the rope. Also helpful video. But much more helpful if the blocks were hung.

[JohnTrucker-ds]

did this but I cannot get the pulleys to pull apart or lower to the ground to hoist something. Any ideas?

[pdloder]

Why are the blocks perpendicular to each other?
Why start in the middle of one?
Lots of why's.

Thank you so much, I have been wanting to know the proper way are corect way to do this, I thank you sir very much.

[transfersystemsptyltd]

Excellent practical video - thank you.

[dennisdanich]

Thanks you did a nice job and solved a problem for me 😀

[treegasmicthearborist]

what brand are these or could you tell me where i could buy these?

[bowlineobama]

I confused when you said top and bottom. Which is the top and which is the bottom?

[michaelsnell]

I started building a block and tackle system with 4 pulleys in each block. How would that differ?

[edwardjones]

Thanks much, I think I'll put little arrows and numbers on each sheave :)

[liquidpaint]

You gives us the better part but you definitely needs a camera person

[TheCompanion-gxbz]

This video stinks because the explanations are not clear and the camera cuts off the knot tying.

Using my wife’s account, to leave a comment. Horrible camera work and a very weak job of describing how to do that. When you want to describing how to do something in an instructional video. Maybe try and imagine your audience like it’s fourth graders so you can dumb it down. Sorry to be so harsh, but that was a waste of five minutes.
