False Crotch (Friction Saver)

[StewartTreeCare]

should i connect a pulley to my false crotch once i reach the pointr i set it at? I climb with the PI line 11.7mm. or would the two metal rings be gentle enough on my line?

I use both systems depending on how I feel. If you have never used a pulley for a DRT system you will be blown away by how much of a difference it makes. Generally I prune from a false crotch pulley system and do removals from a cambium saver with rings.

On a personal note, I have just retired my alloy ring cambium saver as my new steel ring unit arrived. Worst place to use alloy IMO. No matter how careful you are they still get hit coming out of the tree and metal fatigue in aluminium is very hard to spot. Until the ring breaks of course. :jawdrop:

outofmytree is it possible to set the pulley on the false crotch with my rope through it from the ground? and what kind of pulley do you use?

Sure. If you buy a cambium saver with no rings you can add a pulley on a maillon rapide as the small ring and a steel karabiner as the large ring. Inserting that setup into the tree is done exactly as you would a conventional 2 ring cambium saver. I am playing around with a cambium saver at the moment which uses a permanent pulley but that is still a couple of weeks away. I like to test stuff like this to exhaustion before I show it off.

The pulley I climb on is a climb rated open sheave pulley like this.

Check out this video and look closely at the climbing part.

I used an adjustable false crotch, inserted from the ground via throw bag, tied off to a porta-wrap. The pulley in use is the one pictured in my reply above. Sweet system to climb on for deadwooding a tree or indeed any application where you will need to move around a lot and saving friction is important.

I will have a look at the rushes of this video and see if I have enough decent footage to make a climbing system video that may be clearer for you.

I think this is what your referring too. This is from page 27 tree climbers companion

I use a homemade version with the rings (http://www.arboristsite.com/showthread.php?t=119337) . Setting the friction saver from the ground is in the book and is great when you get the hang of it. That book has a great deal of useful info, also "The art and science of practical rigging"

Hope that helps,
