Very neat!!! who makes those green carabiners?

Super materiał, genialne proste rozwiązanie

I would want two backup ropes. Lol

Great video thank you

P.S. Thanks heaps for your videos they are excellent

Video shake is annoying

Is that a rock exoctica?

I've seen water levels but I really didn't understand how/where you'd need them...... traditional line levels or construction levels is all I've ever used or needed but I see here how the water level would work much better than trying to line level across from 2 locations up on a ladder... lmao, it would literally be a handful trying to do all that. Thanks for the share. Merry New Year

I think half the allure of mountain climbing is owning and playing around with all these gadgets. People love them.

In a complex system you have pulleys that move at different rates of speed relative to eachother. For example a 27:1 consisting of a clutch or MPD with 5 single pulleys and 3 prusiks. One 3:1 moves really fast, one moves at about half that speed, and the last 3:1 moves at a crawl. At least that is the easiest way i have found to explain it to people. It is fun to build one and then have the student lift a 650 lb stone with only one hand.

Brother I love this channel!! Have my rescue ops and tech classes coming up, and have been non stop watching your vids! Great content! Thank you and Merry Christmas

WHAT IS A THROW BAG

thanks! what brand of pulleys are you using and what kind are the red ones?

so if you have 9T going to the load, does that mean its 9 times easier to pull the load if you pull on the tail? Also if you have too many T would the rope snap, or does this help the rope snap less?

This is fantastic thank you I’ve been making 5:1’s with no knowledge of compound ma before yesterday and am stoked This is a fantastic demonstration

Good presentation. I would point out that you've employed a Poacher's Knot. The Scaffold knot has 3 turns rather than two.

thanks for sharing

Voodoo!!

👍👊🏽

It's funny that the knot you demonstrated as the "don't" knot, is the primary knot that we climbers use for tying the ends of rappel ropes together, so that we can rap a full rope length (on double strands so we can retrieve the rope afterwards by pulling one strand). It's known as the EDK (European death knot - confidence inspiring, i know!). Even though it's probably not as safe as other options, it's easy to tie and inspect, is only used when a dynamic fall load isn't expected, and only on a temporary setup that is checked immediately before use. I think the primary reason though, is the fact that as you demonstrated, when you pull it tight, the entire knot sits to one side, leaving the other side flat, making it easy more likely to ride smoothly over cracks and edges during retrieval. And arguably being stranded on a ledge after the first pitch of a multi-pitch rappel, and not being able to unstuck your rope is higher risk than the unlikely event that your freshly inspected EDK will come undone during static, low-tension rappel loads. For more permanent applications like prussik and cordelette loops, the double fisherman is what I've mostly seen.

I think I need this for theatre work 😜

I'm grateful for a video that is well and truly educational.good info that illustrates what these simple machines where intended to do,make it easier to solve everyday problems with limited resources

Great video. Clearly explained and demonstrated. Thanks for sharing.

You are amazing and teach so well. You have no idea how much I have appreciated your videos for rescue!

Where'd ya get those metal corner joiners ? I don't know what they are but did you order them or can ya buy stuff like that at home improvement stores. Pretty cool. peace Also, once you're ready to put this outdoors, will you cap the hole just to keep moisture out or is it not a consideration? thanks

Masterful, thank you so much! :)

Good video, helped me out greatly. Would you get the same results if you replaced the two single pulleys at the anchor point with a double pulley?

One of our backyard trees was badly damaged by an ice storm a few years ago, and it had to be taken down. I used a 3;1 to pull on a set of fours to pull some of the logs and branches around when we cut it all up for firewood. I am a small old guy and was able to move and manipulate some very heavy chunks of wood. I love pulley systems!

You have some money invested there! I am filled with envy! I have spent a bunch of money on similar hardware. My daughter is going to have one heck of a yard sale one day when I'm gone.

Your videos are wonderful! I don't believe anyone I know understands how pulley systems work, or how to use them, and I am utterly fascinated with pulley systems. I hunt every year, and I carry lots of rope and pulleys, just HOPING I'll have the opportunity to haul a big animal up a mountainside. I have studied the methods used to haul victims in vertical and high-angle rescues for a long time, and all of it can be put to use when hauling game or just moving heavy objects. It just fascinates the heck out of me.

What is this, why would you want one? Assuming one doesn't have a wood shop with a lathe and drill press, wouldn't it be much easier to just buy a dowel?

Still wondering how did you get down with no descender after you left the Clutch on the ground lol. Good video!

Interesting

Do you have model numbers of the clutch pulleys and regular pulleys?

I guess it is my dyslexia but this confusing to me because your drawing are up side down

Larger auger bits can break your arm w/ a more powerful drill, especially a Hilti Drill or similarly strong one. I once was up on a ladder extending my arms w/ a drill & a 3" auger ..... the drill twisted & lifted me up as I danged for almost 1 minute before I could get stable. I'm sorry, mine was an angle drill but you get the idea about the dangers of an auger, bigger is more so. peace

Neat! It works just like Rope Runner Pro but way cheaper!

It surprises me that so few hunters understand how to utilize pulley systems for hauling game uphill or for hoisting game for dressing or transportation.

You, sir, are the Bob Ross of rope work

WoW, I was using pulley's long ago but I wish I'd seen this back then. LoL, but as I'm older now I've grabbed this channel just in case I've got to do any heroic lifting. This method would make me LQQK good..... or better. peace

i love this video, it´s perfect. thanks PerryFire. super useful

Thanks for covering these products.

SO, may be expensive. What products are you demonstrating, and where can you get them? Enjoyed the video, which is very interesting.

If you are going to suck your teeth and smack your lips when talk. Please move the mike farther from your face. Other than that. Very informative video. How about one measuring the mechanical advantage gained by using a set of fours.

This guys awesome, thank you

How would you calculate the force advantage if pulling rope that attaches to itself and is tying tension around an object. For, say, a treenet, you attach pulleys to prusiks to both ends of a rope and pull them towards one another in order to lock that tension in with a knot. This means that both sides are loads and anchors at the same time?

Where can you buy triple sheave pulleys? I've been looking but can't find anything that looks like it could hold much tension.

Easy to understand and reneber demonstration. Thank you.

You need to focus your camera on the subject matter before posting this mess.

You answered all my questions. Thank you
