Two rope technique on a fir tree

[WildClimbing]

Hi all

 

I use a two rope technique (one primary, one safety) for filming work.

 

I need to install an anchor on a fir tree. Looking at this:

Not sure how this can be installed safely however without the risk of it sliding down because there is no 'V' shape to hook it over.

 

Any advice?

 

 

Thanks.

You will be better off using one of these and double wrap it.  It will bite against the stem if set right.

Thanks. I am installing a platform onto the side of the tree, and when I am on that not all of my tension will be on the rope. Does this mean that the anchor would then slip down?

 

I'll be in the tree for 8 hours at a time.

Can you please explain what rope system/technique you will be using

Hard to describe the name as it is a custom technique developed for the film industry I believe. But essential we run two ropes over a V shape in a tree, and anchor them to a near by tree. Then we climb up the two ropes.

 

However, I need to get up a fir tree that doesn't have a natural V shape in the branches so need to somehow anchor onto it whilst still able to have a primary and secondary rope.

So a suitably rated tape sling with a mallion rapide on the end will probably work fine, just double wrap and then girth hitch the tape sling around the trunk.  It won't go nowhere.

Hire a local climber for help , maybe you can both learn something from each other.

Sounds like the film crew technique is home made.
If you are planning on doing work in trees, simply do your tree climbing and rescue ticket.
It’s a simple enough course and you will learn how simple it is with the right kit and training.

Where are you based? Maybe somebody can help?

No, we have two ropes because one is the primary to climb and then we have a second as a redundancy. Because we have to be able to "forget" we are on ropes and focus totally on filming. So if you do make a blunder and a crucial mistake, like leaving something unclipped for example, we are caught by the duck on a second rope.
