Rigging off two trees.

I think a double-whip tackle is allowing smaller ropes to hold bigger loads. You have to operate it differently to let it run.

From your description its a little confusing. Your best bet is to draw a picture and take a photograph. It sounds like you're wanted to spread the force on two trees but that is going to sideload the crap out of the tree that has a dead top in it. Getting more Hardware involved is probably going to make it more complicated. A steep zip line possibly guyed back might be a way to reduce your forces.

How big of a top are we talking about and what kind of tree?
 
Ive been rigging out trees over 30 plus years, I'm no rookie. That being said these dead white firs are a different animal. Their a scary tree when they've been dead for a while.
They have opened my eyes to looking at the forces created dureing rigging operations. I don't have a specific tree or top in mind. But when that "one" comes up, and it always does, I want to be ready. I want my crew safe. I want to be safe.
I've been putting what I've learned into practice.
I'm not known for my speed, but people trust my judgment. Its important I know how to safely get a job down be it me in the tree or another climber.
I greatly appreciate you all taking the time to explain these things to me and putting up with my questions.

Lots of us are learning right along with you. I always check out your threads because you have good questions.
 
My worse fear happened. A young under trained climber, only 21 years old died on this project taking a 20ft top out of a 100ft dead pondorosa. It didn't run. The tree broke beneath his feet. Him and the top fell into the HV lines killing him un front of his whole crew.
The week before a young 21 year old climber and friend was killed in a bucket truck taking a top.
I don't work for those aholes no more so they can't censor me no more. What a waste. Both could of been prevented.
 
We take calculated risks sometimes as climbers. Its takes years of experience to know whats safe or what isn't. Even then sometimes its a crap shoot. I lost a buddy 25 years ago catching a top in a healthy green tree. The big pine broke at the base. It haunts me even today.
But I do hazardous trees. Im not fearless, but I am carefull and experienced. I don't let no one influence me or rush me or direct me. A new climber doesn't have any experience to base his decisions on.
You can learn a technic, or read about it but its not the same.
On a project that needs 100s of climbers the bar is lowered. Greed kills in this buisness. Thats all I have to say.
 
Very tragic and words are at a loss for me also. Also a deep scar for our industry.
RIP young men.
Beastmaster I realize this hits home for you ..... don't beat yourself up.
