Why do you make this so complicated? I can do the same thing with 5 carabiners (doesn't matter if locking or not), 4 standard pulleys, and 2 gibbs ascenders (handled ascenders shouldn't be used in tensioning systems), or even cheaper, some 6mm prusiks.
The force at the ascender is 3 times what it is at the ropeman. If you swapped the ascender out for a ropeman, you wouldn't be able to get the rig as tight: the ropeman would start to slip. I have not tried using a tibloc or shunt, so you'll have to try those out yourself.
Yeah that makes sense. I had never actually used a shunt and only really saw how they work earlier today and Im about positive that its use in a similar setup would be pointless.
Have you ever tried removing the pulleys from the system after tensioning using a secondary line locker and anchoring the line while at tension? Ive heard of this but never tried it, was wondering if you knew what was up on it
good system man. i would just replace the traxtion pulley with a grigri and then it would make it stronger and WAY easer to de-rig. i walk a 350 foot slackline today using this method but with a grigri instead of the traxion pulley.

You could all just set up a SLACK LINE You just need a length of static rope (usualy hemp) You tie it off between your two static points with a simple one and half turns and two half hitches. The rope sags in the middle and is set just above the ground. If you fall you only fall a few inches. great practice for the dynamic line as discribed above. Does nobody out there understand the definition of the word SLACK!
with a line this long, it's very likely to sag to the ground and end up being less of slackline and more of walking on the ground. the description says even with all this, he still got 5 feet of sag in the middle, meaning the line has to be more than 5 feet off the ground, which can be dangerous. without the complicated pulley system, you'd probably have to have the line waaay up high to avoid touching the ground.
You can back it out by reversing the steps you used to tighten it. You need to pull on the system a little bit to release the traxion pulley.
A faster method, if you have extra rope, is to tie the rope to the slackline side pulleys and then pass the rope through a carabiner with a Muenter hitch as a brake. Then pull on the tightening system to unlock the traxion pulley. Control the release of the system with the rope and Muenter hitch.
what is the final mech adv? like 10 to 1 or some such minus a little friction? good lord. now that is a haul system. everyone's gonna put in their bullshit 2 cents anyway because there are tons of ways to build haul systems.
The slackline brothers pulleys give you 4:1. When you add the ascender and traxion pulley, you bring it up to 12:1. The ropeman and final pulley bring it up to 36:1. Actual advantage after friction I haven't measured.
you guys could make it quite a bit easier by making your setup a 6-1. It's what I use with about the same length of webbing. Just don't crank down hard after youv'e put the webbing under your first loop, do it again at the beener with the clove hitch. Makes your pull so much easier. Cheers and keep on slackin...
And then you blow an anchor and all of a sudden you have a shit ton of gear flying at you super fast... Hopefully the minitraction cam will hold under all that force. I would strongly recommend removing the SBI block from the line after you finish tensioning it.
I understand that, but, it's still not that hard to blow an anchor. Trust me ;-) Plus if there's even the slighest weak spot in an anchor with that much tension on it, it can make for quite the ride. At least you're wrapping it several times. If an anchor did blow you would have enough time to get clear.
is it the same for highlining?

The rope should be attached to the none anchored pulley... you get more mechanical advantage.

I'll set up whatever length line I want to, gosh.

what is the diameter of the static line used in your pulley system?

this is good for those who have money that can buy all this gear, not cutting down vid but you can do this with just 6 beeners and some knots

Could you replace the ascender with another ropeman, a petzl tibloc, or shunt?

Great tightening system. I have actually setup several times; however is there an easy way to take down, after all the fun?

ok... you set up a 100ft line with no tensioning system. let me know how it goes..

How much do we have to pay for all this gear?? 3 thousand dollars????
pirobin66 4 years ago
slackline brothers pulleys $191, traxion pulley $75, ropeman $38, petzl ascender $60, standard pulley $20, 100' static cord $90, 200' 1" nylon webbing $60, 200' 11/16" nylon webbing $50. Extra carabiners and webbing for anchors $200. ESTIMATED TOTAL: $784

hey, do you use standard aluminum carabiners or steels? seems that with such a long line, steels might handle it better.

1 inch tubular is rated to 4000 lbs. A single loop would be a marginal anchor for this setup, so we use 3 or 4 loops.

The Petzl Pro Traxion is a pulley with teeth and cam action to prevent back sliding.

thats a pretty sweet setup, not that i'll be using anything that long anytime soon... but the ides are great.
