Blue Mountains - male climber injured after fall

In all honesty I think it would just be rather nice if Daniel sent "The Lady" her gear and a simple thank you card.

Shortman, there is absolutely no problem with using a grigri trad climbing. None. I've used it exclusively for years now unless I'm using doubles. I rap, haul, rope solo and belay with it.

People like to say it creates too much force on the gear, but it is the device of choice for aid climbers, and that's a place for trouble if what you're saying has any validity.

Good to know.

Too much force on the gear?? Dunno about that. Wouldn't it be like all belay devices and depend on the user?

Huh?

Totally agree. However, when I look into my little crystal ball, I see a dude who has been f*cked up for the last 6 months still sitting on a hospital bed trying to save his foot first, gear second, and communicate on the internet third.

Maybe I've got it all the wrong way round??

Yes and no. Mike has the numbers somewhere, but a tube style device will slip at a lower force than a gri-gri will.

Nick is saying that If a gri-gri causes more force on the gear, surely in aid climbing that would be a bad thing.

Yeah but it's a pragmatic, attention there in that context. You can be belaying one pitch for very long periods of time.

Pretty sure he still ain't in a hospital bed if hes got time to post shit on here and Youtube, pretty sure he should have time to contact Ness to return gear..or actually be home when he said he would when the cops come around to pick the gear up on Ness's behalf.

Fair enough. I still find it strange when people whip out the gri gri though.

Plus you can't respond to you emails as easily.

I've aid climbed for only two pitches. The first time was aid practice and my partner managed do get a dozen emails done in the pitch. The second time was the roof of Passport and I don't think he had good reception. ;-)

Not just pragmatism (in a long attention span context), but physics of higher impact forces (as ajf reference of slippage threshold), on marginal (read bodyweight only), gear.

I agree with fishboy re gri gris, but I have never bothered to buy one for my own use!

~> Back to topic.
I think Wendy made a good insightful guess regarding the possibility of the climber maybe starting before the belayer might have been ready. Easily done in a bad communication environment, and could easily account for a large fall becoming larger still, due not being able to be controlled in a timely manner.

As a side note, in many other disciplines there are penalties enshrined in law for negligence and incompetence, ... ~> I wonder how authorities view this accident, and subsequent seeming disappearance of the belayer involved? ~> ~> It is this aspect alone which tends to shake my faith in humanity, rather than the plight of the injured party.

Probably a bait that I am about to swallow, and call me old fashioned, but I reckon there is a time and place for that, and it isn't while belaying; ... as that is like trying to text and drive at the same time.
Yes it can be achieved, but potentially at what cost??

It wasn't bait. It did occur. But no, it is not best practice! As long as you secure the brake end then a gri-gri will happily lock up.

Gri Gris lock up generating a higher force on the gear. With practice if the belayer gives a soft catch belay by hopping up lightly at the right moment the impact force can be greatly reduced. Now falls can happen any time but an attentive belayer will watch particularly when pre warned about marginal gear. In saying that I still don't belay trad with a gri gri because that is another thing to get right and with high consequences for failure - not something u want to get wrong. I use gri Gris for sport and working routes and occasional aid as the risk of letting the rope go by accident on a 5 hr belay is quite high.

Exactly! But only for small falls.
The extra amount of 'cushioning' you can generate is the small distance you step up, handy for a small fall and inconsequential for a large fall

From the tests I've seen it can be a fair bit even for larger falls. Much more that the "extra" amount of cushioning from a step up. It surprised me a bit...

Unfortunately my google fu couldn't find these tests...
EDIT: Here is a little data, but not what I was looking for. I recall reading this in a European research paper.

One of the blind spots most climbers have is belaying, what works for sport (small falls, steep rock, bomber gear. The main issue is avouiding being slammed into the wall) doesn't work for trad (potential long falls and poor gear. The issue is a balance between avoiding the ground and overloading gear). And vice versa (so getting a traddy to belay you on a sport route is as bad as getting Glen boy to hold your rope on something scary. And lets not start on double ropes)

Also, on multipitch you are tied into a belay and grigris will generate large forces

This article from Beal might help some gain an understanding of the differences between belay devices (and ropes) when looking at fall factors:

I've said it before and I'll say it again. I prefer that my belayer uses a self-locking belay device (ie GriGri) for trad, sport, aid - whatever. The reason is I like to know that if the belayer looses control (lets go, gets hit on the head by a rock, gets distracted, falls asleep) that the device has a backup. The off chance that a bit of trad will blow by being shocked loaded by a GriGri is negligible sideffect for me. I generally climb routes with bomber gear, and double up as much as I can. It is very very rare for me to ever blow bits of trad gear.

Related anecdote: just got back to U, S and A from a work trip to Barcelona, where I managed to drag myself up this beast (mini TR when I get a chance), and the guy I was with (a member of the Montserrat cliff rescue team) insisted that I use a reverso, rather than the ATC I'd brought with me.

His argument was similar to yours Neil, and made sense to me given that we were complete strangers (he's a friend of a friend). That said, and with my limited use of the thing, I'm not sure I'd trust a reverso to completely auto-lock in the event of comprehensive belayer failure, but it seemed like it'd perform better in that case than a vanilla ATC...

Except tri cams, right? ;-)

And link cams too, right? ;-)
