Primitive Slackline Setup
Вставка

- Amazing line for beginners and intermediates. Also one of the easiest and cheapest setups out there. Only 4 carabiners, 2 rings and a 1 inch tubular webbing (20 to 30 meters for 15 to 20 meters of walkable line) are necessary for this setup. The knot that is shown during the video and that is used to attach the slackline to the tree is called a mooring hitch.
Exactly what I was looking for, a way to add more mechanical advantage to the more common primitive system. Thanks!
I have never seen anyone set up a line quite like this but it’s ingenious! I will never need to ask a random stranger for help again because of the mechanical advantage you have created with this.
I’ve also never seen anyone not use anchors and just create them with the slackline. Fabulous! Trying this out today!
there isn't mechanical advantage perse, if there are no pulleys is not really achieving MA, whats happening here is that all the progress you achieve is capture by the friction between the webbing. ;)
This system offers 15:1 mechanical advantage (although theres a lot of friction so its probably more like 7:1 with rope and a progress capture) which can put a heck of a lot of force on a line. This system is pretty cool, and would probably be great for small children or a single lighter adult, but the amount of force a normal size adult, or multiple, is way way way to much to maintain a decent safety ratio with this set up (welded rings, aluminum carabiners, 1 inch tubular nylon) I don't know for sure, but I'd be willing to bed money that the weak point in this system it probably the knots on the anchors, meaning in the event of a failure there would likely be a lot metal flying very quickly. I know this video is from 2015 and no one really rigs like this anymore but to anyone watching this looking to set up their first slack line, its probably quite a bit safer, no, it is a lot safer to use much less tension. I've heard some really awful horror stories about primitive systems failing and people getting hurt. As a good rule of thumb, its always ideal (but not realistic) to have the webbing that you walk on be the weakest part of the system, then the line lockers, then the master point, then and anchor sling, then the actually tree/what ever other anchor you are using. This way if god forbid something does fail, there is probably just webbing getting pulled toward trees. Its not realistic to assume everyone has line grips and steel biners and spansets (especially if they are watching this video) so its probably best to just get accustomed to lower tensions. Sorry to rant, dont mean to be that youtube comment safety freak, just wanted to put this info out there. Take it for what you will and do what you want, at the end of the day its super unlikely that this stuff will fail, it can just be bad when it does. Anyways, awesome video, and cool systems, I've never seen that carabiner handle trick before!
I appreciate this comment.
Do you know of a safer way to set up a primitive slackline?

I’m not sure your math is correct. Isn’t the system he shows a 6:1 mechanical advantage? 3:1 for the first z-drag then a 2:1 on top of that?
Thks ❤
I just got a primitive setup for myself. Thanks for the video, Martin!
Thank you for the videos on the most helpful videos out there
Genius! Best instructional video on this subject
Thank you so much for this very informative and helpful video!
please keep in mind that climbing carabiners are usually made from some kind of aluminium alloy and they have no true long life fatigue strength. So using them in a slackline setup might lead to break eventually. Steel would be better. Also be mindful of your load distribution in the carabiner.
It's definitely a good point, that's why I tend to use slackline specific carabiners (I do not use them for climbing!!). Those oval, non locking, aluminium biners are cheap & still very strong for the purpose of rigging a primitive slackline
Waaaay too complicated, seemingly. BUT so freaking genius in the same time!!!
Its cheaper doing it this way because other channels require you use either static line or other webbing as an anchor. Im glad I found this vid haha
Complicated??? More like how to take your simple set up and make it dope asf !
Primitive? This is so much more sophisticated than using a ratchet!
kind sir: I don't have fancy carribeaner or rings. I go with trucker's hitch. By itself, it has 3x mechanical advantage. But, instead of just pulling tension with trucker's hitch, I rig another trucker's hitch to pull on the tension line of the trucker's hitch. I get 9X mechanical advantage for my slack line tension. It works inexpensively. No need for expensive rachet or caribeeners.
Thanks for sharing
Genius!
Block and tackles work great don’t they
Wow Amazing
where can I buy that green slack line ?
your awesome
Since you use a hitch for the multiplying system, why can't you use a hitch for the very first carabiner you add to the line instead of a linelock + carabiner?
Does this work with 2inch (50mm) lines too?
Yes it would work the same but may need larger carabiners
Is it possible to make like 40-50meters walkable line in this way? How many carabiners and other stuff should i use in the "tension system" to make it possible? If its even possible. cheers dude :)

It is definitely possible, and I've done this before, with someone else helping me out!
It will however require 6 biners as a minimum (maybe have an extra 1 or 2 as handles), as you'll have to double up the "tension system".
Also, you'll probably want to have it at around a 2 metre height on the tree to account for sag.
+Martin Ham thx 4 the quick answer :)
+Gergely Igaz
let me know how it all works out for you :)
it's the first setup I used, and still love it for its simplicity!
Hi Martin! Sorry, I´m pretty new to this rigging method. I see that you suggest to double up the tensioning system for a longer line - how exactly would you place the biners in? I don´t suppose it will be simply doubling them up and looping everything the same way,,?
Btw, love your simple multiplying system, its so easy and smart bro!
Hi Michal,
In order to gain more mechanical advantage, simply repeat the same method that I explain at the 7th minute of the video, and add the first of the 2 carabiners, where I placed the red (8th minute). In theory you could do this as many times as you want, but the more you do this, the more tedious it becomes, and the longer becomes your tensioning system...
Let me know if you have any further questions or if you don't understand my crystal clear explanation ;)
How long have you been Slacklifing?? Every other video i have watched would not use their webbing as the main anchor around the tree, they used separate webbing as an anchor. You just saved me tons of money haha! Thank you so much!!!
Balance Community sells scraps of webbing (up to about 70 feet) for relatively cheap. I bought some of this webbing and then tied the ends of it with a water knot. Possible alternative to buying closed loop anchors :) Happy slackin'!

Chase Aldridge Good point!! Really good point! Thanks
what is the name of that knot ?
girth hitch it seems like
I believe it's a mooring knot
It's a quick release bowline knot
Interesante
Hey hey, a little less of the ‘primative’ guys. This is how we used to setup slack lines on non-climbing days before commercial slack lines arrived in the scene. Or am I being too ‘vintage’ or ‘retro’?
I would also say it’a far more ingenious using friction to hold the line than a simple ratchet.
