Zip line install

[arborworks1]

I need some help and information on zipline work. I have a botanical garden that I am working on getting a canopy tour setup for them. Its still early on in the deal.

I have a good idea about the working and installation procedure, just some tips and hardware recommendation would be good.

Have you looked at the new Sherill catalog? Might be some ideas in there. I found some really cheap, strong rope that replaces cables that I like. I will try to find the name of it, might be duravet by Samson. What components do you need help with?? Back up everything!!!!

Good luck.

I'm wondering if I should run two lines one above the other and link the pulleys together as an ultimate backup. One line is taking all the weight the other is the safety. Also the anchors in the tree has got me questioning myself.
That is a pretty good sideload placed on a tree, and this is going to be in a swampy environment, I'm thinking that guying the tree back would be a good safety measure as well.

ACCT....cover you ace on those set ups....Zip lines in the ropes course industry have the highest injury/ death rate. Not to scare you but..........


zip lines installed come under sorta product liabily-t shat. If the masses will be riding, ...I would be ware

I have some of this line and love it for zipp lines. CHEAP AND STRONG. Bear to work with as it is as stiff as cable so you cannt tie knots in it but is low stretch and doesnt flatten out

Yeah definately guy the tree, we were going to do a job and had to zipp everything over the house . Was about a 500' run. I ran all the no.s and it is amazing the forces a 200lbs piece can exert over that kind of run One thing I can tell you fo sure is dont over tighten the zipp line as the force on the line is worked out by some formula that involves the load being devided by the sag. So if you tighten the line and the sag becomes 0 then the force is infinate!!! Sooo dont try to take all the slack out

Hope you getting paid big for this........

Actually I'm not even sure that this is going to pass the gardens higher ups, they have been throwing the idea around for long time. Just getting a picture for the proposal.

In Denmark it is mandatory to put a second line in for safety, whenever you make a zip-line for people.
I have set some up for the forest service and having to do double back-up on everything is a bitch. But then losing a passenger would be a lot worse.
It can be a little tricky to get the grade of fall right if the line is run without the pullback line acting as a brake.
You want it to work for a small kid as well as for a fat dude, so the grade has to be such that the kid doesn't get stuck midway and the fat guy doesn't break the sound barrier and dies from the shock.

I say kill the fat guy
