Petzl preliminary conclusions

[kevin bingham]

No Petzl USA gave this presentation at the TCIA conference and I snapped a screed shot. I think it was very informative and it made me want to put a load meter on my climbing system. I think that it would be really interesting for everyone to know. You could have it go directly to your cell phone and record the loads you put on certain parts of the tree during a climb

To me it's always been a gut feeling, I have been climbing on base ties for a long time now and always felt more comfortable with this than a top anchor, not to say I do not use top anchors. VTIO touched on this in a article on SRT and it just made sense in my mind, it also comes from installing pulling lines from the ground V having them top tied, it never felt like I was getting increased pull through the double loading, in fact it felt less because of the amount of line absorbing the pull energy.

I hope what I say makes some sense.

correct me if I'm wrong, SRT climbing exerts more force than Ddrt by 50% on the anchor point. the initial perception was as high as 100% more, if we were to just hang statically, but that would then make that rule superfluous because we always have to climb. to conclude as theres 60 - 70% less forces on the TIP with base anchor in a fall situation. that means the top point would have a higher SWL. also if the force is compression rather than a levered force. that would have to make SRT with a base anchor substantially safer. well from an ultimate fail perspective
