That was a beautiful demonstration of understanding force vectors, equipment function & usage, with a joyful comfort level that is impressive. Bravo!!!
Came in from Texas and visited AT a couple of months ago. Excellent people there. I may offer that, after you attach your releasing rope, tie an Alpine in that same line about 3 feet from the connecting end. Biner on the Alpine, then route load line through the same biner. When the load is released, the releasing line doesn't fall and can be retrieved by simply hauling it back up the load line. Be safe!
Not into climbing or ropework, but I stumbled across your videos and found them very interesting. This particular one intrigued me. Why is it the jammer is able to slip when connected directly, but doesn't slip once disconnected? Change of angle / direction of force? My understanding was that these things gripped whenever there was force in the direction they don't want to move.
They do grip in one direction. It’s a special way to open it so they don’t open accidentally once on the rope. I don’t like this technique personally but it will work. It’s just not 100 guarantee it always will. Doesn’t mean the rescue still can’t be done, but it adds to the time frame of getting them out, which during a rescue, time is of the essence.
Nice video! Have you experience doing it in reverse? Say, operator at the top still, but hauling the casualty from the bottom up to a point mid-way along the tension line and then lowering off.
obvious question, what about retriveing the basic...is it like guy has to go down the tension line and get them, then back up...or is there another way?
Are you using the Petzl Mini pulleys? I tried this a couple weeks ago and am looking pulleys that work better than what I had on hand. Love yalls content! Thank you.
Woooah, great stuff! (...great staff too!) ^^ I'm totally astonished about the trick, but... yeaah... the longer... the more i think about... GREAT! What's your experience with that: Does it function with (nearly) all kind of angles or should it be near 45°? Could be that it works with all kind of angle, but the force onto the loop will increase the more steep the angle is, isn't it?
one thing i can't understand is- those basics are sliding down the tension line, so how do they lock at the point you want to lower the casualty off? why don't they continue to slide down?, when I did this rescue for my L3 at Access Techniques I used shunts instead of basics
Trigonometry. Once the casualties weight is loaded onto the diagonal line (zip line/luff line), the casualties gravity will pull the crolls' back in the operators direction (in their lock direction). This is achieved after the retrievable sling is removed.
