Aerial Rescue Counterbalance Technique.

[High Scale]

Sounds pretty simple.

they're more complex when you have a back up rope as well and you have to have 2 points of contact, or climbing through a rebelay.

 

if they are too heavy to counterbalance the way i said above, sticking a pully on the jammer a pully on your bridge and a second pully on the jammer and threading the footloop through all three should give a 3:1 mechanical advantage. i had to use a 4:1 while rescuing a guy on my IRATA level 2 as he weighed 24stone:ohmy:, therefore overloading the anchors instantly. ( swl rope 250kgs - strength loss of a fig 9 (30%)= 190kg, 36 roughly equates to a load of 240kgs)

You lost me on the 36 for a bit, combined weight!

Should the rescue climber always be heavier than the guy in the tree??

 

Maybe we need some more legislation??

 

 

that has been my general experience of groundies anyway:001_tt2:

aye, he was a big guy, but got around pretty well with cracking technique

Thanks guys, all useful stuff, still got to get my head around it somewhat but once i have a play with it im sure it'll make sense.

 

Jamie, how did you IRATA training come about, are you using it for work currently?

i'm not in the trees just now. i'm painting the forth rail bridge. fancied a change with more prospects. miss the trees though. still dabble from time to time but the skin on my hands is soft now .
