hello,
was wondering if any one knows how to do a good set up of a saftey lanyard that works with a micrograb and pully?we use the old adjustable one and im having a hard time tighting it around big trees with the knot so far away from me was told that you can use a micrograb and pulley to make it alot easy and one handed but can see how to set it up off the d rings i have a new flip line and micro grab but could someone show me somehow to do this safe thanks in advance for your help
 
If you use a micrograb, there'n no reason or need for employing a pulley.

Most folks have dispensed with the micrograb in favor or a friction knot and pulley. French prussic, knut hitch, among others work well. others use an english prussic which is bidrectional, which allows use of both ends of the lanyard. It's bulky and complex, but some have set one up with slacktenders on both sides of the hitch to allow one handed adjustment on each side.

For steel core flip lines, I still prefer a micrograb, especially for work in pitchy conifers, which tends to gum up a friction knot.
 
thanks i worked with the flip line and micgrab today dont think i need a pulley works well without it.anyway to use tthe extra line with a clip for a 2nd saftey like a 2in1 thing or is this a bad idea? the company req.us to use 2 saftey lanyards at all times thats why i ask

Baaaad idea. The Micrograb only works in one direction.

Two lanyards or two point of attachment? A 2-in-1 lanyard would not count a a second point of attachment. (ANSI Z133.1-2006, 6.3.8).
 
Its where your lanyard can work in either direction. With the Micrograb it won't hold the rope if you pull in one direction but will if you pull in the other. A 2-in-1 will hold both ways thats why it requires the use of a micro-pully behind it to tend the slack with one hand. A prusik knot or the Klimair would be a 2-in-1 untill you added a micro pully, then they just become a positioning lanyard.

A 2-in-1 is nice because it allows you to hopscotch branches in the tree without ever being detached from the tree.

I hope this makes sense?
 
Yes, it makes sense and is sometimes handy. Sherrills has a new(?) device in their catalog which will mechanically grab in either direction and it looks promising, but I really, really like my Grillon...
 
I got the Petzl micro grab on my wirecore lanyard. In my humble opinion, it is crap. I use a pulley with it if I can, cause the slack is real hard to take up without it.

In the UK, we have to have a 'soft link' between the wirecore and the D. Same in the US?

In Soviet union, micro grabs you.

Just my two cents.
 
I tried the grillion once for about two weeks and I liked it. It seemed to adjust out smoothly, under a load. The Klimair I use now is a litle more sensitive to that but it swivels so my body never releases the "switch."

What is a 'soft link'?
 
A little more sensitive to that? As I understand it, you must unweight it and use two hands to adjust. The Grillon does indeed adjust out smoothly under load; under what conditions did you experience it "releasing the 'switch'"?
 
A "soft link" is a cuttable link between the wire core and the harness for example a short tape sling. This is to enable easy rescue as taking bolt cutters up a tree to remove a wire core under tension would be bad news indeed, compared to a knife to cut the sling away.

Right on the button!

The soft link can also be your friction knot, although, I guess, most people use mechanical grabs on wirecore lanyards.

I have a 4 inch tape sling I link between the crab and the eye of the grab. I have also used prussik rope in the past, but it was untidy.
 
I can usually adjust the Klimair out with it under a load, not a full weight bearing load mind you but a well balanced load between your legs, saddle, and laynard, it just takes a little finesse. I threw a small steal accesory biner behind it to tend the slack, no pully, just biner. The times I did use the Grillion my body would come into contact with the release switch and I would find myself releasing the tension while I hung there without doing it on purpose. I suppose that might have to do with being left-handed and keeping it on the right side of my body.
