falling logs

Thanks guys... interesting, so the bottom line is obvious I guess, you don't want the groundies holding up the climber. If a groundie has his/her ear protection on, head down cutting logs, they can't be watching or listening for signals from the climber.

Some of what I hear reminds me of what a former coworker who is isa certified told me, that some people actually rig off (hang&lower) logs to the tree they are in. I have a hard time believing that some one would be crazy enough to play around with those kind of forces.

I rig out wood around a ton on a regular basis, and if I can build the cost of new rope into the job, I've gone much heavier. My riging blocks have a 2 ton SWL, why not use them to the limit?

JPS-do you rig these logs so they hang in the tree and then get lowered ot of tree you are attached too? Or are you tied into another tree while doing this? I dont question the strength of your blocks or rope what I question is the strength of the tree, but if you are in another tree I guess who cares.

Bothe, there are many ways to engineer a job, but sometimes you just have to block the big wood off it'self.

There are a number of friction breakes on the market that will reduce the force so your not slamming the wood down ont the rope and catching it. If the load runs and the force is dissipated into friction on the brake you will not shock the spar as much as if your running through a natural crotch and taking 3 wraps around another tree.

I'll do everything off the same tree, however ideally I would be lowering out of an adjacent tree. Like that you don't have as much of a shock load to the rope, plus often times it takes a lot less effort to set up.
