(I'm going to say this as quietly as possible). Sure, why not.
-
I see. Do you intend to get the twin bollard for the double snatch blocks or were you thinking of something else? I imagine it would be very tricky to lower onto two different sized bollards (grcs and portawrap for example). I have never tried a vertical speedline. Shall have to do some research. Paul

I agree with the cranes for big timber bit. What will you be changing from and too with the rigging kit. What were you snatching in the demo? Do you have some figures? Just to elaborate slightly on my earlier point, Harken recommend up to 14mm for the self tailing winch jaws. The larger rope recommendation comes from arborists and refers to the bend radius of the winch bollard. Paul
-
Paul, if they cost the same which one would you get? Who believes that the GRCS is more cost effective in terms of speed and man power? Minutes matter! A visor plate coupled with the huge aluminium bollard for large snatches. It's feasible to chop and change the two throughout the take down.
-
Better to check Harken's spec's. I'm pretty sure that the winch feature isnt designed for ropes over 14. A 16 can be used and a rougher covered lowering rope like the orrible marlow braid actually winches quite well. GRCS all the way.
-
How exciting Drew! Best wishes for the go-ahead.
-
Yes, they are replacable. The wear time depends on how you climb. Doubled rope technique will put hardly any wear on the plates. Single rope more so. Check out tree buzz for more info on this. Climbing single rope my first set of plates are still perfect after 8 months. It's a great tool, one that I heartily recommend. Paul

Did you start selling the Rope Wrench?
-
Thanks Mr Bingham. If the line is loaded vertically can it change to ascent mode? If the f8 doesn't run up I guess you need to clip your handled ascender above f8 and then remove.

He has started to walk upright again and occasionally he smiles.

Yes. Kinda. Sometimes you can find openings and work a second tube from one point.

You obviously haven't got a jetboil yet

...and 500kg is a lot of wood.

Petzl always push this with their pull-outs and catalogues. When I bought my GRCS it came with no literature at all. So it was over to the forums for learning and to the work site for gradual trial and error. I think that we should rig with multiple kits and each section has a dedicated role. But of course we could debate what goes where for a good while....although there is no disputing that drop test. Thanks for posting it.

It's a very famous quote...Donald Rumsfeld. -
Now what is the message there? The message is that there are known "knowns." There are things we know that we know. There are known unknowns. That is to say there are things that we now know we don't know. But there are also unknown unknowns. There are things we do not know we don't know. So when we do the best we can and we pull all this information together, and we then say well that's basically what we see as the situation, that is really only the known knowns and the known unknowns. And each year, we discover a few more of those unknown unknowns.

Dave, there were two stems that had been topped, the only pruning history on the tree and both of these were vastly altered. As I mentioned in the first post, the central 3 or so stems had extensive dieback, like the sickly children of the tree. The rot extended past the bulge, at the bottom of the topped stems and nearly down to the floor. It was at least easier to cut.
-
Thank you Mark.
-
A fine sense of achievement indeed. We all did very well with such a tight drop zone. No moaning, no griiping (sp?) and everyone worked like troopers. There was chicken of the woods on the floor Dave. The photos show yesterdays last rig, setting up the bollard, said drop zone and finally the quartering of the trunk. http://db.tt/vBlv5Vv http://db.tt/gtxm63K http://db.tt/exSVYPu http://db.tt/GQi9aY7

That's cool. Much less chance of marking the bark that way. Do you mean John G of Tree Climbing Japan? I'm moving over in October. It's gonna be fun Sorry for the slight derail. Paul

: I use a 9mm whoopie for a trunk belay. PPE An 18mm whoopie for a flying capstan. Rigging A 13mm loopie for re-direct. Rigging A 9mm loopie for re-direct. PPE A 9mm whoopie as a tether for non-CE certified Unicender. PPE Some I have spliced, others I have not. All is fit for purpose. Does it have no more standing in court than a shoe lace. Really?!! Why does a LOLER inspector pass it as fit for purpose? Are they wrong, am I wrong? If I were to work on a smooth barked parallel stem I would wrap several times around with a looong cambium saver or a length of PPE dedicated rope.
-
Mr arghshh wants to choke on to a stem. A cambium saver doesn't fulfill this requirement.
-
Yes. Buy a length and splice your own?
-
Good idea, a loopie is even better!
-
Thanks for the kind words. We finished all the winch sections today. Managed all the leads except the rigging point and lifted off the bulbousness of the stem. Tomorrow will be a run up and chog down and then loads of blooming sawdust clear-up. Here are a few more from today. http://db.tt/PuPSZVo http://db.tt/jhe1nlD http://db.tt/mmEekxL http://db.tt/QpJgCUz http://db.tt/29iYSGc
