Let's pretend that I am
a very lightweight belayer.
-
And my climber takes a huge fall
-
which drags me up into the wall.
-
And if I panic and let go
the brake side of the rope
-
to protect myself.
-
While my grigri gets trapped
in the first quickdraw.
-
Is this gonna kill my climber?
-
I already made a video showing that
-
if you press on grigris cam
-
and not hold the brake side of the rope
-
that might end up fatal.
-
So let's see if quickdraw can also
-
unlock the grigri's cam.
-
If you get trapped in it.
-
If I am pulled
-
so hard...
-
Wow!
-
I mean that was like
one shot experiment...
-
Though yeah well if you move maybe...
-
You will be going down...
I still filming.
-
No, no. Keep filming.
Yeah, it goes down.
-
So if I would not be holding this...
-
Yeah, if I don't hold this...
-
The climber goes to the ground.
-
So yes, quickdraw can
unlock grigri's cam.
-
But to make this experiment even better
-
I wanted to see what
happens in a dynamic environment.
-
Where i would fly up and
jam into the quickdraw.
-
Unfortunately i'm not that lightweight
-
to fly all the way from the ground
-
into the first quickdraw.
-
So instead I decided to clip myself
with a separate quickdraw
-
just below the bolt,
-
so I would need to fly less.
-
Pulling.
Yeah.
-
Ah, no. The rope got pinched...
-
Pulling.
Yeah.
-
Oh, no!
-
Whoa, the rope... oh, man...
This is crazy what happened to the rope.
-
So first few attempts
the climber was 'saved'
-
by the rope getting trapped
-
between the grigri and the quickdraw.
-
Or in some cases even
wrapping around grigri's handle.
-
Which you definitely
don't want to happen.
-
But then we got this.
-
OK, pull it.
Yep
-
Whoa!
-
Yep, Yep.
-
All my backup went in.
-
So if i would not have this hand on,
-
my climber would be on the ground.
-
Attempt number two.
-
I'm gonna give you
-
one meter of
-
backup rope.
-
Yeah.
-
Whoa.
-
Yeah.
-
So here you go. Another reason why you
-
should never let go
the brake side of the rope
-
even if you're belaying with the grigri.
