Ascending with GRCS

Here's a video where it didn't go to plan but... the breaker on the extension blew out and the groundie wasn't smart enough to push the button. He was a little buzzed out. and found it hard to even hold up the drill.. How I do soo much with so little is beyond me.. will try in a larger tree soon.
 
Wat kind of shock load can that micrcender take? I used to use on on my lanyard, but witched to a VT... I saw an ajustable tether on a double handle ascenders system yesterday, which I thought was cool.. It was on a knot though.. I've heard bad things about shock loading micros and toothed ascneders... You only get to die once!

I've ascended on the GRCS on one job. Deadwooding 5 tall oaks at the end of the day.. Set a floating false crotch (pulley) and did a little hand over hand to help the drill which was barely able to move me... only used a stihl gas drill. Fast and easy. The groundies would get me set in the top of one tree then, pull the GRCS and shoot a new line in the next tree, while I was pruning, so it was ready to go by the time I made ground. I haven't seen the key around in more than a year though.
 
The ascender that I am using is the Unicender. I too have used the stihl drill with the ascent and barely got me up. The drill that I was using here was more than enough causing some concern as I was rubbing against the tree. I am not following what you say "I haven't seen the key around "?

I don't do that without a back up safety.
If that rope slips or comes out of the GRCS you're a gonner.

Actually if the rope comes out of the GRCS I then can come down. I am tied in when going up on the winch through the unicender. If the rope that is holding up the pulley and my rope was to come loose or get cut, That could be a problem!!
 
I've done it many a times.

However, it is in this type of situation:

I use it when I'm pooped out from rigging or I really need to pee, or I've been working for a long span of time and I need to get down.

(As I'm sure, most of us like to wait to take a break when we're close to the ground because it is more efficient on the body, right? Why descend to the ground if you're 50' up there only then to ascend 50' once again?)

Anyhow, my reason for descending had better be a good one.

So, I'll use the ascender & drill combo on a separate rigging line, which is in a block. On my way up I am pulling my slack out of my VT. This way, the effort to ascent is 1:1, therefore faster getting up there.

That set up, on your video, is 2:1. You will ascend 2x slower than what I've explained above. Try that and you'll love it!

I get confused with this stuff but isn't that the same way I got it. Through a block in the tree then my climbing line through the block and down to the GRCS? Is that 2 to 1?
 
Jamin's tryin to bamboozle yu Ricky, don't fall for it.

Shame on you Jamin, now focus on my shiny watch.....back and forth...back and forth.....focus on the watch.....follow it my sleepy friend.

Let me see if I can bamboozle and hypnotize too.

One climber on the ground, in his saddle with a single climbing line attached, his line runs up to the top of the tree's tallest central leader and through a block secured to that leader.

But now a second climber at the block on the leader pulls up a 200 pound tear drop weight and attaches it to the climber's line on the ground right at the point it comes out of the block in the top of the tree.

If the first climber on the ground weighs 215 pounds with his saddle and tools on, and his line runs up the tree and through the block with the 200 pound teardrop weight attached to it in the top, how much does the climber actually weigh now and how much effort will it take to overcome the 15 pound weight disparity to reach the top and the counterweight hits the ground. He would in some respects now be a climber that can move up the tree only weighing 15 pounds.

Now imagine this counterweight as a 200 pound gas driven prtable air compressor that supplies 120 psi to the climber through the middle of the climbing line to power his array of lightweight pnuematic chainsaw and loppers.

Would it work?

Is it practical?

Or is it a crazy attempt to bamboozle and hypnotize Jamin?

You're on to me...
 
I should have tried for a larger tree but now I see how fast this can be getting up the tree. I just need a groundie with some strength and all will be great.

Na. I couldn't ask that of my groundie. I bought the chuck for the GRCS so that we can use a drill.

I mean that my groundie could hardly hold up my drill and I think it weighs 35 pounds. The kid is 125 pounds. I checked out your website, looks good and great work!
 
How about using the GRCS as a capstan winch and have the climber hold the tail that is wrapped around the winch. When the climber tightens the tail on the capstan you ascend by pulling tension on the tail, or release tension to stop and go at will.
