Hey I know this is an older video, but I have recently seen a video of a guy doing this technique which I’m sure he has learned from you all. Thank you for your amazing knowledge of our beautiful industry.
That's good, Rip. Except, when we've done it, we've had a GRCS or Hobbs as the lowering line friction, which allows for rapid slack removal during load free fall, which can reduce the amount the load falls by a considerable percentage, which also limits the peak loads. As well, I sometimes use full static HWMPE rope for the speed line, which totally reduces line stretch to near zero
Hello, this is an awesome video and thank you for sharing your knowledge with all of us. Could you tell me or teach me, maybe even a training video on how you attached your lowering rope to the section of tree that you just removed and lowered to the ground? Thank you, Carlos Martinez
That part of the rigging is called negative blocking. He passes the rope through the block and places a marlan or half hitch above the face. Then he ties a running bowline above the half hitch. The half hitch keeps the loop of the bowline from opening during the fall. Hope that helped. Go to animatedknots.com to learn the knots. :)
Very nice. Sometimes I watch these videos and think to myself "why didn't I think of that".
These ISA videos are great for worried customers with lots of questions. The videos are slow paced, comfortable, and professional.
One of the better videos! Keep them coming!

with the right tools a large piece of wood may be lowered safely .. great video
that is a lot of extra work and extra time

I want a grcs real bad.
"Letting it run" ( to decelerate ),...Contradictory terms...

Seems really time consuming
so does rebuilding your house when one of these things finally blows over in a storm.
@@dungeonmaster6292 i do tree work and i tell my clients all the time "its cheaper then fence work or its cheaper than a new roof"
@WungusBill climb tall, cut small
it is a lot of extra time
