Use of friction devices in tree tops.

I've got a mini porty, I'll give it a try.

It sure is a PITA setting up the mini porty, block, sling all in the same few feet, then trying to find a place for your rope and lanyard. Surely dropping a top directly on the porty would solve that problem.
 
Sean, want me to come down with the GRCS/Nobbs? We'll take those hung trees in one piece, if the gin pole trees are beefy enough.

I've gotta come down to Kapwosin soon and do some trees for my bud Wayne. He was my number one ski model for years. Later, he scored a great Powder Magazine cover. Maybe I could stay for a coupla days.....I'd be bringing my number one ground man...errrrr woman.

Roger, there isn't room to lower whole. The tree in which the uprooting tree is resting is only about the same size, not much larger. Thanks for the offer. I think that it will be possible to do it safely without needing to lower the whole tree. Winch it off, drop the top, chunk it down, and how the roots will support the spar enough to slack the winchline and remove, then fell the spar short of the fence. It'll be a good use of my new-to-me 12K Ramsey winch ($100, needs some battery leads, couldn't pass that up!)

The dead madrona leans heavily toward the primary. The HO is thinking that the power company PSE might be taking care of it. It will probably be a waiting game. HO will ask neighbor if we can drop across the neighbor's property, after building up with some logs on either side of the driveway to prevent damage from the log hitting the driveway.

It'll be drop and leave. The homeowner has a backhoe. Once the son fixes what he broke when he high centered it on a stump (Oops!!), we'll be back in action.
 
Sean, I probably don’t have to tell you this, but when you winch off the uprooted tree from the other one, try to get as direct a fairlead as you can to prevent any twisting that could occur due to having a poor lead. Obviously, its best to pull directly from in back of the lean. I would also consider using a couple of side tensioning lines to guy the uprooted tree better before taking out the top and piecing it down to where it is safe to fell the remaining stem. I had a job just like this this past spring and I posted about it with pics here on the Buzz. I’ll see if I can find the link.

As far as catching a small top in a porty, I’ve tried this too before and didn’t have much luck. As the top came over and slack was introduced into the system, the porty rotated slightly and the line became fouled. Not enough that I couldn’t lower it, but it was a hassle. One thing that could have been done is to set a regular block to catch the piece and then set the porty below the block to lower from. I have done this a lot of times and found that it works well provided the porty is low enough so as the block rotates with the top and lands on the stem, the porty is out of the way so it won’t get pinched. Obviously, it’s a little more work to set up and you do have to descend some to reach the porty, but as long as you’re taking small tops (and pieces), I have found that it works all right
 
Chris,

Thanks for posting that. Its good reference for people. You had the exact plan in mind. Great minds think alike...


Fools never differ!

My pleasure. Glad to be able to share knowledge with others on the Buzz. So many people here have helped me out over the years, that I will happily "pass it on" whenever I can.

Technical rigging is what my small company specilizes in.
