count the ropes not the pullies -
Ariel rescue- THE method for rapid ascent.
Craig Johnson replied to Tony Croft aka hamadryad's topic in Climbers talk
i was playing around with this about 10 years ago, did an artical for treeline about it. i used a rope grab and small pullie instead of the top hitch climber or blakes, then with the addition of a throw line tied to the cam you can retrieve the top system. tony if you use this system you dont need 400 foot of rope, you install the rope, make the floating pullie, tie on you hitch, pull the pullie up untill you almost run out of rope for your 3:1, climb until you reach the pullie, then sendthe pullie up again:thumbup1: repeat. -

why not reduce before felling? much better for the wildlife and PR even if they do not recover at least you ''tried to save them'' and from a contractors point you can olny fell a tree once:lol:

the itcc started putting extra bells in 2007 but the scoring only changed a couple of years ago, 1 point or part of for every 2 seconds insted of 1 second slower than the fastest time. rhys lost 20 points for not removing all his gear in time (he had miss tied his apline on the access line)

from past experance a popular harness with the smaller ladies is the hightec tree hopper or for other 'sizes' the tree flex is good as the girls are more comfortable with the lower on the hips fitting of this harness

if the tuck on the blakes is on the wrong side, this will cause the knot to slide, with a quick glance at the knot you would not notice. stick to prussic when training
-
yep thats how i tie it
-
when i tie the helical i cast the top turn over to make it cross works much better, will dig out a pic
-
a break away is quite hard to make as the forces are not alway the same, i dont think the throw line/or carritool break away is that good, it could be too strong if the tree fails slowly or too weak in normal working. the quick realses is a more predictable option, but must be simple and easy to use as importantly as quick, as when you need it it must be second nature. i have some of those shackes, used for rigging demos so they do release under load, if you want i'll put one in the post.

where abouts will the work be based? (i guess it will be sweden, but where)
