Dead Oak

[tod_k]

We removed this dead Burr Oak on Friday. Seemed like just another job. Upon evealuation turned out this tree was really dead. Anything 2" or smaller you could break by hand. And there were 45 mph winds. here it is at noon.

Turned out to be no big deal. It was kinda fun because we got to use a new mount one of or GRCS's. There are some really nice improvments. One is a second pigtail. This is really nice because the operator can now pretty much go anywhere they want without bending the rope around the pigtail. We have broken or bent ours by putting too much friction on it. Plus the second tail lets the operator have a clear view of the work and not being in the drop zone and not bending the rope on the pigtail so this also gives the operator really consistancy with the loads letting them do a better job.

Another improvent is the mounting of the tails. They are much stronger.

Last thing. There has been alot of talk about spar work and tie in's. Here is a technique I have been using for some time. I really like being srt for spar work. When using just a running bowline I have had limitations with retreiving. When using an inline clove and caribiner I am concerned about configuration. So now I just use a ring and a gri gri. I use this for manual work when My rope guide is too short. I do not use for crane work as I will retie into the crane to rigg the next piece of wood.

I slide the ring onto the rope and then feed the rope to the ground. I then tie the ring into an alpine butterfly then feed the rope through the ring back to the ground. Install the gri gri to the standing part of the line and abandon the hitch. Works very well. Moving down to the next piece is a cinch. And retrieval is great.

Nice job Tod. Couple of questions.

Why the stubs in the first photo?

In the last photo--orange line is a rigging line?

Gri Gri is on the left side of the green line, and the abandoned hitch/'biners on the right side?

How does this differ functionally from a running bowline? Just give you more rope to work with?

Hope all is well.

Very well done Tod.

I was wondering about this too. Also, do you find alot of debris ending up in the GriGri after each each cut that could effect its performance?

Stubs, well a bit lazy. The orange line is a pull line for the felling. The advantage to the ring is it is very easy to get back for your next position or from the ground. With a bowline I have had difficulty retrieving, often climbing back up. The ring is also nice compared to a link, no improper loading to worry about. And finially all is well, how about yourself? Oh yea i have been using a gri gri for many years during tree work and rock climbing and am very comfortable with it I have never had a problem with debris.

Sounds pretty good. I'll have to try it out.
