Forget about one handed saw use, it's the camera I'm worried about!

Heartland, if the limb you are cutting is being speedlined out, what is the purpose of the three pulleys?

Butch,
It's called "The Fishing Pole Technique" You've never seen that before? I thought that was relatively common.
It is really poor practice to cut and drop loads onto speedlines. You do understand the load amplifications that take place? The cut should first be lowered onto the Fishing Pole limb then the speedline is used to move it away.

Uh, yea. I've seen the 'fishing pole' thingy before, in books. Never had a reason to use it.
It appears like a waste of time to me.
I assume it is to put less 'shock' and 'strain' on the limb.
Thats all well and good.
Back to my question... Why is he doing that if he is speedlining the limb out?
Where is the 'shock' to the limb that requires any, much less three pulleys, to do it?

I think I see it... he has a line attached to the limb to control the descent?
THATS gonna stress that limb that much?

Three pulleys???

It took me a while to wade through this thread. There's some interesting shots. Watching the videos is pretty cool.
Could people give an idea of what the jobs entailed, pruning/removal/ cut and run/ cut and cleanup and then give a price? It's alwas interesting to see what work goes for in other parts of the country.

The speedline rope is left slack, the cut is made and lowered onto the fishing pole limb. Then the limb is moved off using the speedline once there isn't a slam dunk load.
By taking hte time to set up the FP on the way up, the cuts are rigged when it comes time to work the chunks down. The end rigging is taken off as the climber moves down.
How do you know what strength there is in the limb? It could be a weak wood, be cracked, any number of reasons. Its not as obvious why rigging is set up as it is to wear hard hats.

Cool, dude. Someday I may see the need to use it.
I'm sure the people that make those pulleys hope everybody does it!
Ya never know when that big, bad limbs gonna getcha!!!

A buddy of mine from PHilly uses large, steel shackles when he riggs [ ] Put the screw pin in the eye of the sling and the rope runs on the loop end. He's cut the U part our of a second shackle and welded it to the one with the pin to give a bigger radius. Less effecient than a pulley but cheap and durable.

Never cared much for the fishing pole system as shown there...
Maybe use it some day and I Am sure the math is impressive at reducing/spreading loads.
I do think some discussion of the speed line load amplification is in order....
I believe there is only amplification when the line has less than an 18-20* bend in it.... So as long as there is slack or plenty of stretch in the line.... no amplification... That's the way I like to set up a speedline.... of course the trade off is hieght.... with that much angle in the rope you loose a lot..... Most of the time when I set up a speedline (which isn't too often) I have enough height...
This saves a couple of steps and plenty of time... I won't use a control line unless I really need one either...

It's no wonder this thread has so many views. There must be at least ten sub threads going on
Heck, the fishing pole could have been spun off and now loads on a speedline is coming to the surface.
Will this be the thread that never ends? JPS might have to make up a new forum for this one...

I'd like to see Riggs do that, Murph!
At appx 3800 lbs if maple or oak, that is triple the weight that I've lowered off itself. A 1.25 inch line would be needed to keep to a 10/1 rigging load factor. And a spectra sling rated for 70000 lb, due to double loads at the anchor point.
I think heartland was involved in an Arbormaster training..thus all the perfect placed (over) rigging.

How's this for light wood?
Not a bad way to spend a saturday.
I'll give extra points if you can identify the tree from the wood.
No rigging pics, but thought these came out cool.
Guess we'll call this tree unsavable.

Just guessing I'll throw out Willow.
