I wanted to get a pic of him ascending with three blocks and assorted heavy slings.

We were taking down a previously topped basswood here.

I had an easy day as ropeman.
 
I almost pity him... I NEVER carry that much crap up with me in a tree. Guess I'm a minimalist.

He is to unless going up a big removal, another low friction beleiver. Set the main block move the second around as you go. The small effort of getting it to the top is worth the economy of the entire removal.

I'm moving to using more blocks after having so many pullies get damaged. More spring-blocks are on my shopping list.
 
The verticalpro lock block would be a worthy investment if it can be proven the coefficient of friction between rope and block is lower than rope and a natural crotch.

No pictures of OPG, sorry.

I am starting to like the products this company has and am asking for more info. I think they are local here in Ontario so perhaps I can get a look at the blocks and other equipment in person. Their ascender looks really nice too.
 
This idea has been on the website for years, but they are not for sale. I wonder if they are facing patent issues because of the marine blocks which have the exact same load sensing feature. We have several on the scow I race on and they work great.

Getting the proper amount of friction is the same as with a port-a-wrap, if you need more, add a wrap, only at the base of the tree with a second brake, or take a smaller hunk.

The idea is a good one, I hope they are available soon.
 
If you want to know about Vertical Pro products ask the co-owner. Dave Spencer is one of them and can be found on the ???????? and ISA sites (cutrighttree?).

The "clutch" mechanism is different than marine blocks.

The adjustment comes from adding wraps and the load apllied by the groudie. The basic principal is no different than any friction device going back to the basic three wrap system.

I’m going too have the opportunity to try the second generation of lock block which is completely different than the one pictured, can’t wait to try the hand ascenders as well.

Also in the works is a device that allows quick whoopie sling repositioning without retying.

Marine blocks are either engaged or disengaged, at some preset tension.
Are you saying that the amount of drag changes with the load inside the block somehow?
 
Jeez...you guys haul that much crap up there every time? He looks like a cross between a lumberjack, a telephone lineman, and a ball of yarn and metal! :D

Hehe to me, it looks like there is rope everywhere...which one is actually gonna prevent him from falling? :p
