9:1 Mechanical Advantage

[@johngo6283]

Well, that last great tip about making an entirely second anchor for the second 3 to 1 that is 30 feet away is totally brilliant. Never heard that one before. Great idea.

[@threeriversforge1997]

Great video. As a blacksmith, I love showing these videos around my circle so guys can better understand how easily we can move heavy equipment in the shop. Too many have forgotten that ropes and pulleys even exist. Costly to set up, sure, but worth it in the end if you only need to move a power hammer or lathe.

[@royceanderson3389]

Thanks for your Service and your explanation of the 9 to 1 Mechanical Advantage set-up.

[@DickRoethel]

Love practical and simple ratios!

[@ianbrown_777]

Good that you explained how to get both travelling pulleys to reset at the same time. Never seen that mentioned before.

[@motionsick]

Dope. I just went backpacking and used a 3:1 paracord setup to pull dead branches off trees for firewood. Need to get a 9:1 setup now. 😅😅

[@jeffm9227]

Well done.

[@matthewsalvador9783]

Cool gonna move a shed doing this method... I could use the buddy system or my truck, but this method will show me what my limits are. Hehehe

[@davidsteinfeld9123]

lots of rope lots of pulleys not so simple but one man can​ do some enormously heavy pulling or lifting provided the skill sets are correct skill is everything. were proper technic is important to that's a biggy thank you for the knowledge the good stuff is always harder to find

[@markh16]

nice videos on pulleys! Are the Prusik ropes strong enough for all the load?

[@dangerstall]

Yes, because they are only taking a percentage of the total load in a mechanical advantage setup, and a prusik will slip if overloaded. They tend to slip at about 1200 lbs of force for a 3 wrap prusik hitch. Give or take depending on materials and diameters etc...

[@JS-zb1vv]

Depends on the load and force applied at the anchors gotta remember the force is applied in more than one direction

[@cjpirotelli8640]

Great Video! I have a question though.. what would the ratio be & what would happen if you made the 2nd redirection attached to a rope grab off the back of the progress capture pulley instead of the rigging plate?

[@dangerstall]

If I understand you correctly, I think it might make it a complex 11:1 . You would have to reset the pulleys so many times though.

[@cjpirotelli8640]

@@dangerstall Thanks Ryan! Yeah I used it today, not ideal but only had 4 pulleys in gear bag. Luckily I only reset once. Thanks again, really cool channel. Looking forward to more videos

[@eakramulmohammad3867]

Well done 9 to 1

[@jormaruohoneva1588]

OK :)

[@jbs-vu5mc]

What kind of pulleys are being used?

[@dangerstall]

Rock exotica Omni blocks

[@amoledor]

What pulleys are you using?

[@dangerstall]

Rock exotica Omni blocks

[@southern_merican]

i only see a 6-1. shouldnt you add both 3-1 together instead of multiply?

[@dangerstall]

When you put a 3:1 onto a 3:1 it multiplies and becomes a 9:1.

[@southern_merican]

@@dangerstall ok. Its been awhile since i messed with anything more than truckers hitch and a few others

[@bullitt5337]

you forgot your progress capture ;p

[@bullitt5337]

disregard that I missed the progress capture pulley my bad

[@TyShep06]

Progress capture?

[@dangerstall]

Is that a question or a criticism? As you can see there is a red prusik next to the first COD pulley. Unfortunately I never got around to attaching it in this video. It would go on the prusik minding side of the first COD pulley.

[@alfredoacevedo4437]

Why not use a block and tackle?

[@Dan.Chaytor]

Alfredo Acevedo gravity

[@JS-zb1vv]

This takes less rope in a resettable system. But this is essentially block and tackle

[@alfredoacevedo4437]

We just have to trust that it works? Why not just hang the stuff up?

[@Dan.Chaytor]

[@alfredoacevedo4437]

Why on the floor, on your knees, dude?

[@Dan.Chaytor]

[@garrettoetken8718]

Actually a 5to1

[@dangerstall]

Please explain to me how this is a 5:1? Also explain your background and what makes you an expert in mechanical advantage pulley systems for rope rescue. Thank you

[@troyhornback1719]

Steve racer says it’s a 4 + Garrett says it’s a 5 = 9:1

[@banryu79]

Wrong, it's a 3:1 on top a 3:1, so it's a compound 9:1 system

[@K9SolutionsLLC]

It's a 6:1 fellas. A 3:1 with a 2:1 compound. 3x2=6:1

[@dangerstall]

Please go learn the T method for calculating mechanical advantages and let me know what you think after.
