Slackliners in the park play with 4kn. Longliners may see 8kn. Highliners see no more than 7kn in normal use. Trickliners play with 15kn!!! And 3ton trickline webbing breaks around 26kn so there is not much safety margin.
Thank you Olga Henry (@olga.henry), Dylon Lousberg (@slack.dylon) and Dillon Vance (@trampwalldillon) for helping with this episode. Thank you Davis Hermes and Joe Wachter for donating gear for this series!
We have a new free Trickline E-BOOK by Olga Henry now!

How much force is Dylan putting on this trick line?
We have a dynamometer on this ratchet trick line and then we're gonna get some
pulleys and pull the crap out of another trick line
and just bounce. When I say we, it's them.
We're gonna bounce and play while we find out how much force trick lines are
dealing with. Find out on this episode of How Not To
Trick Line.
No way! Hi, I'm Ryan Jinks and welcome to the park
where trick liners roam free. We have a line scale two and it's going
to tell us how much force this trick line has. Dylan Loosberg
and Olga Henry are going to play on this. We're going to play with tensions.
We're going to see if they... At what tension I'll be happy.
What tension she's gonna have. She apparently likes it tight.
Dylan was okay with it, you know, a little bit looser.
So when the line is being used by a long liner
it's at 3.5 kilonewtons. Probably gonna step it up by like 12
kilonewtons more. So we're now at 6.9 kilonewtons on the line and we'll see
how much tension one click of the ratchet will bring on.
Okay, ready? Yep. Again. 7.2 to 7.4.
Again. 7.4 to 7.6. So basically if we need to go to 13
how many clicks? I don't think it's linear. It's not.
Definitely not linear. It's not, it's not a full two.
The diameter of the spool that he's going around is
smaller over there and I think that might have something to do with he's not
getting a full two every time he ratchets.
Yeah. It's like one to one and a half plus it's on that side and I wonder if
that has an effect to it. Because this was just like right here.
The energy end I think settles throughout the whole line
and that's why another reason, one of many reasons, it settles back down
when you bounce on it. Yeah. These are regular.
What's a non, what's extra spicy? Wow. Oh get it to 14. You're at 13.99.
These are some gnarly forces. Yeah. Can a heavier person who doesn't
bounce as high? How much do you weigh? About 180. And how much do you weigh?
160. Wet? Wet. Gotcha. All right. Yeah. Let's see what an extra 20 pounds does.
I didn't even go on the scale.
Wow. All right so. So you're at 10.8, 11.5.
Just find your center and keep your center. You're at 12.5.
Oh god that's dangerous. 12.6. Is it polite to ask you what you weigh,
Olga? Is it polite to ask? No you can't. All right.
What was that experience like? It was stressful. Yeah?
Yeah I got it. You looked fine until you weren't.
That's usually how it goes. 12.7. So I'm 10.47.
Wait. You're satisfied? Like close to it. Oh you're a hard to
please woman. 13.3. You need to get to 14. All right.
So attention, Olga likes when Olga's tricklining.
Those are the forces we're playing with. We use kilonewtons because everything is
rated for kilonewtons. But since tricklines are rated for tons,
we will go to pounds here. This is with nobody on it. We are over one ton right now.
Over 2,300 pounds. Will you do one more bounce for us?
That actually, the resting tension didn't actually rise nearly as much as I thought it would.
Because we put a ton of tension on it, right? Yeah.
It was like sitting somewhere. We only put like 400 pounds worth of resting tension on it.
We're one and a half tons or 3,000 pounds right now.
We're going to find out what three ton webbing breaks at in our slack snap machine in another
episode. Yeah.
Yeah. 3,250 right there. 3,300. It peaks around 2,100.
So this is pounds of force now. And pounds of force is easier for
some people to understand if they're not used to newtons.
So now we're going to change the units while he's... Oh, that's... Okay.
So we're going to put peak force on... So at kilonewtons, kilonewtons is what a lot of
the gear is rated for. So your peak force right now is 11.7.
Nuh-uh. Yeah, you got 12.34.
So you're dealing with forces that are insanely high.
And a lot of webbing is like, what do you call that? Three ton webbing or whatever.
And you're basically at one ton. You're above one ton.
Will you do that again with pounds of force? Yeah.
So the same thing here, but pounds of force is 2,400 pounds of force.
The big bounces are getting 2,700 pounds of force.
2,700? Yeah, that sounds about right.
You're playing with one and a half tons and this shit breaks at three tons.
That's crazy. Well, they're called three ton webbings.
I don't know what... We're going to find out on Slack Snap.
Yes, let's do it. Yes.
Okay. So we now have a pulley system trick line. We just made an episode on how to rig
a trick line with a pulley system, and you can learn how to do all that in our other video.
So let's find out what forces are involved
with a pulley system versus the ratchets we've already looked at.
Yeah, I'm really curious to find out how much tension I can put on a trick line,
and then two people can put on a trick line, and then three people put on a trick line.
Pre-tension until you can't anymore? That's a pre-tension.
Okay. What's our pre-tension force?
Oh, it's actually very close to what we got on the ratchets.
Throw the multiplier.
But it's one person for pre-tension.
Yes. One person pre-tension. Let's do an all-go-to-one.
As hard as I can. It's actually easier when you put two feet like this,
and then you lean back, and then you straighten your legs. Let's look at the best way to pull on
that. So that's an all-go-to-one. One person pulling 5.70.
Let's see what I can do with this.
With a 15-to-1. It's a 5-to-1 with a 3-to-1 multiplier.
It's almost like the first tension we got on the ratchets.
Yeah. You're trying to get to 10 or 11.
Wow. 6.70 by yourself, right?
I'm going to help her.
Yeah. One, two.
I guess, should we pull out more?
Yeah.
One, three.
One, two, three. One, two, three.
Whoa.
Whoa. Two people.
So let's see what three people can do on a 15-to-1.
Wow. Wow. That's amazing.
12.3.
Wow. Olga might be happy.
12.3.
Dang.
It's too tight. That's the sound of too tight.
Okay. Well, I think when you're on it, it'll settle.
Yeah.
So it fluctuates between 11.8 and 14. So let's hit peak.
14.5. 14.6.
15.1.
15.55. You called it.
That's sick.
Yeah.
Give us a 16.
Did not go up. It did not go up.
Not at all.
What's also settling at the same time.
Yep. 15.8.
Wow. You called it.
Let's see what tandem does.
Wow.
It never went up. It never peaked higher because you're not on it at the same time.
And it has now settled to 11.
11. Wow.
You lost a full thousand Newtons.
So you are playing with 10 to 15, almost 16 kilonewtons when you are tricklining.
So be careful, back up your stuff and make sure you're using good webbing
because these are dangerous horses.
Please don't die or trickline.
Cheers.
