killer bees

I think I understand generally what you're describing, but not all the details. Hopefully we can go over some of this SRT stuff at the NJAISA meeting on the 16th?

2 wraps and then a running bowline?? Or just plain 2 wraps?

And you've got to make sure the rope is 3x's longer than the distance from the ground up to the crotch, right??

Thanks Mark, for the info.

2 wraps and then anchored. I like midline knot and krab myself.

Yes, the rope should be twice the height to the crotch on the running side. Or, connect both sides and run a loop. He had a loop.

I hadn't thought of that mark - any pics?

Bees and wasps are pretty cool over here until you start cutting, and even then, I haven't been swarmed badly, but one pissed off wasp is enough for me to bail out! Killer Bees - thats way too scary /forum/images/graemlins/ooo.gif I always anchor to some kind of lowering device, or a locked off muenter hitch. I dead end the line with a running yosemite bowline, then tie an alpine butterfly to clip the lowering device. I'll pull through all the slack till the ascent end of the line is just off ground, then attach the lowering device. I hang a purpose designed weight off a prusik to the ascent end - easy to slide up as the stretch is taken up through the chest ascender.

Its encouraging to hear you endorse SRT, especially with the back up for these situations - how often do you climb like that? /forum/images/graemlins/smile.gif

For those concerned about rope length, if you use the Petzl tuba to anchor the line, you don't have to worry about the length of the line - its designed to pass a knot from a loaded line. /forum/images/graemlins/wink.gif
 
Mark, could you tell us a little more about using a loop instead of the extra long line??

Let me try and take a pic next week. The main idea is that you use an ascent line that is anchored in a way that will allow a person on the ground to unlock it and then be in control to lower you. That's all.
 
Yeah Friday we had a removal to do on this bank just near enough to a parking lot below that some people wanted the tree gone ( top was dieing and had fruiting bodies on the root flare). Just as we set our lines in the tree we moved the saws over and wham white faces started the swarm and sting. ground nest at base of tree. ran our behinds off for 20 feet or so and lil buggers still came so into a building we went till we saw no more. Had to go back later in the day with 6 cans of spray and four guys to get gear out. try hauling lines and saws and such out of an area with 3 others spraying their butts off like a mini war and a evack.
Mark it would be cool to see the pics and how to rig it.

Yes Mark,
I would like to see some really nice pics of this,
and some do's & dont's, Thanks.

Tree Guy, your welcome.
 
I never flip when I discover I'm working in close proximity to bees, wasps or hornets and they rarely bother me. In fact last year we were mushing logs out of a back yard and there were bald faced hornets on BOTH sides of the logs and I was hauling them out on my shoulder at face level with them and we just sort of co-existed. That's not to say I'd do well after totally disturbing a nest though. My friend lept into a pool after being swarmed in FL...they waited at the surface for him. Whiz
 
Here's one solution. It combines a frictioless hitch and carabiner and then finishes with a dbl. fish connection. A rescuer would have to unclip the krab and then could lower the climber no matter what height the tree was. The only difficult part is unclipping the krab when loaded, but can be done with a little muscle.

As simple as that - nice pics Mark, and thanks for sharing the technique!

I suppose the froggers redundant footlock prusik could be tied on the line above the krab and stood in to make unclipping easier?

It also means no expensive lowering device or extra long ropes, and saving time checking rope length.

Nice one mate! /forum/images/graemlins/applaudit.gif Makes SRT even more favourable!
 
One technique I'd like to incorporate is a small hitch above the krab to adjust the loop a little and allow the rope to be unclipped easier (is that what you were stating?). It's a technique we used in Italy for lowering an ascending "victim" from a tall (148') Platinus. It also adds a little more "auto-lock" security.

Glad you like the idea. /forum/images/graemlins/grin.gif
 
For those of us with severe learning disabilities, could you explain what knot is above the krab and what it does....?
