Cottonwood zipline

Hi

Noticed that in one instance the zip line was attached to the stem you were on... above your lanyard.. but your main line was anchored in another tree/stem. When reducing the final stem when you must tie in on that stem.. do you still use this zip line freefall method for smaller blocks. Suppose it comes down to your experience and judgement but after watching a talk at this years Arb show I was surprised at how much lateral force is produced by a speedline/zipline whatever. Don't want you to get snapped off...your videos are far too good.

You should always take every tree and situation at its own merrit, but experience is a big factor. I was always tied in to the same tree I was rigging off throughout that job. Side loading can be hard on the lines....so the line angle, tension and load size must always be considered and adjusted accordingly. Thered lots of little thing you can do to make your situation safer, like re-directs for example....same as conventional rigging. As for snapping the stem, well, on those particular trees I'd have to go some way to match let alone surpass the windloading those trees have had to withstand over the years. Side loading is never going to be the most comforting feeling when you're the guy in the tree, but you have to put it in perspective. Thanks again.

Thanks...

Had another look and now can see how you are using a redirected line...clipping below with the cut piece...so obvious now

Arran, just 2 guys pulling around a friction device. You don't need to go super tight with such high rigging points.

 

JRH, the carabiniers are just fine, steel twistlocks. Much heavier loads and tighter lines might show some wear....as well as making for a more dangerous operation. thanks again.
