Rig N' Wrench

That is a sweet little light rigging set up. Is there a good deal of unwanted friction when climbing with the rigging line though? Or is it easier than I'm thinking?

Check out the brief cameo of his rigging wrench. He says it handles 1000 lbs tops with ease.

Great video and great rigging. BUT there is a lot of needless 1 handing of the chainsaw and at2:47 he put a hand on the body of the saw with his fingers close to the bar and chain which is very dangerous. Im not looking to start a 1 handed conversation but pointing out what I saw.
 
I really like the idea of having the extra friction at the rigging point, but not losing the ability to lift when needed. Very cool. Would be great if this could be used in conjunction with the swiveling Omni's. But the rated becket on the Pinto Rig looks quite ideal.
 
Here it is with 3/8 tenex deadeye. I really am lovi ng this Lil device. All my ground is doing lately is untieing the limbs and dragging to chipper. Don't have to wait for someone to hold the rope for me.

Correct me if I'm wrong but doesn't this put extra force on the rigging point? Something to consider when using? Regardless I love the idea for side work when I'm working with someone who knows little to nothing about running rope
 
It reduces load on the rigging point. With a pulley ir is almost double the weight. When there is friction on just one leg it lessons the load. There is a good article by David driver in the articles section which I credit for putting me down this path of thinking. If the branch weighs 100 but the groundie is only holding 50 lbs ( not real number) than the force at the pulley is 150.
 
You do have to worry about the direction of the force though. With a straight pulley the arrow points straight down the middle. With the rig n wrench, the arrow points more towards the load side which may not be straight down the stem and that could raise concerns in some situations. Sometimes I would prefer 200 straight down the stem than 150 off center. You can also use the rigwrench as a redirect and not the final pulley.

That's exactly what I was playing with, today! Used my Omni-Block for the main pulley, and the rig-wrench setup for one of the two redirects.
This is a really sweet setup when you're just lowering small stuff. I'm also going to try two of these setups and see how easily one person can lower a limb that is tip & butt tied for slow, horizontal limb lowering (as when lowering smaller stuff down onto a roof below the climber).
 
That's what I've really mainly been doing recently. Going back to tip tie ing a lot of stuff. Havent done that since i first got the grcs and i used to cranksup absolitely everything. With this, The groundie can put tremendous pull on it, 140+ lbs depending on groundie, but then the groundie is not jere up in the air when it comes over and swings. This put my medium sized removals in hyper drive as far as production goes. Pull aNd drop all day.
