You had me until you put pounds into the list. Fight the madness! Down with imperial measures!

Also, you didn't have barbecues or beer in the list. Surely that's a mistake.

How about this crazy idea: If the anchor is a ways behind you, stand slightly sideways, with the anchor rope running down over one hip/thigh? Or if the anchor is nearly below you, run the anchor strand down between your feet.

GO


How does this lead to broken ribs? I'm having a hard time picturing being secured to a tree via haul loop could end that way. Has this happened to you?

Hasn't happened to me, no. But I have had friends crack ribs (it takes surprisingly little) and I know what happens when you secure a harness from behind.

Picture this: rope or sling to tree behind you from haul loop is tight, and you catch a hard lead fall. What happens?

You get a a few kN of force on the front of your harness pulling forward and up. Since the tree and sling behind you can't budge, you have an equal amount of force from behind you. Now your harness is trying to go from an oval with you in the middle to a straight line, and the only thing that can give is - you (humans are pretty squishy compared to the gear).

Make sense?

Just to be clear about the alternative (which is actually the standard): Both the anchor and the lead line are secured to your belay loop. Then you stand somewhat sideways, and a hard fall simply pulls your belay loop in two directions. This will not hurt at all!

That much all makes sense, and I can't imagine it's a comfortable situation to be in. I've seen lots of people clipping in to the haul loop for this purpose, but never seen a lead fall in this scenario, so the degree of suffering is something of an abstraction to me.

Mostly I was curious about the specifics of the ribs being a site of serious injury in this situation. I was thinking abdominal injury would be all - the ribs seem a little high.

The strain on the muscles will do it. Corsets still crack ribs even though they are meant to suck in around the fleshy part.

I checked with Arcteryx. On my X-350a I have a plastic d ring instead of a haul loop. They don't even reccomend bringing up a rope clipped to it.

I work in the Challenge Course Industry and there is a High Rope activity called the 'Swing Shot' that utilizes the rear haul loop. Essentially the participant is attached to the belay loop in front to a suspended vertical cable, then the pull line/release is attached at the back of their harness. They are then hauled into the air in an arc and released, creating a giant swing. Harness manufactures cater to more then just Rock Climbers...;)

Only time I ever saw someone anchor in using their haul loop their leader took a fall and crotched himself on the rope (anchor wasn't exactly positioned right). Needless to say I popped off my route and laughed liked I used to when watching America's Funniest Home Videos.

I knew it. Every time there's some weird feature on a piece of climbing gear, it turns out it's there for some bizarre sexual purpose. (By the way, this explains a lot about GriGris).

Oh, and, your post is worthless without pics.

I'd like to see a video demonstration of how to escape a loaded belay while anchored in to the back of your harness, and belaying off the front. :D

'Cause it's more awkward to use 2 to tie the prussik on the anchor strand behind you than doing it one handed.

While there are a thousand ways to skin this cat what your suggesting doesn't really come in as one of the easy and obvious ways.
1. Secure belay device to go hands free. (tie backup)
2. Tighten prussik to climber side rope, and attach to anchor.
3. Release belay device and let slack out until anchor is weighted.
4. Remove belay and escape!

It's the "attach to anchor" part that has you working behind your back.

It doesn't. What does "haul loop" vs. "belay loop" anchor tie-in have to do with this terrible incident from last year? EIther you're tied in when lowering or you're not.

He and others have been saved by having the trail rope tied into a full strength haul loop when all else has failed. Yes, they all should have been tied in by other means. But when the primary rope didn't save them (or wasn't being properly used), it was the fact that the trailing rope was attached to a full strength haul loop that saved their ass. In such a circumstance, if the trailing rope had been attached to a gear loop or other non-rated loop, they would have died. Al's accident was not the only one in which I have heard this happen. I don't use the haul line to anchor with, bu when I trail a rope, I make sure it is attached to something that can take a fall.

As I interpret it, this is not an argument for full strength haul-loops, it is a justification after the fact. I fail to see anything in the accident report that defends the use of full strength haul-loops, or promotes their necessity. Yes it saved him, but human error was the cause of the accident. Or have I just missed something here?

Background info: 90% of my climbing (in Australia and the UK) has always been on half-ropes. I have only used a tag-line once in 10 years of climbing.

Argument/justification...you can call it whatever you want, it's just semantics. Regardless of the cause of the accident(s), the fact remains that climbers lives have been saved by full strength haul loops. I can see it being even more of an issue with aid climbers, who almost always climb with a haul line, and where masses of gear and ropes possibly lead to confusion. It may not be a matter of life and death, but losing a haul line from a broken gear loop would be terribly inconvenient. The way I see it, if you're going to put a loop on the back of you harness, you might as well make it full strength.

Wow there is a lot of assholes responding here.

The full strength haul loop is for bringing up a haul line. While indeed, full strength may be a bit of overkill, it was not that long ago, that gear loops were just stitched and broke around 10 - 20 lbs. In the event your rope gets snagged, or some dumbass grabs it, the full strength loop offers a whole lot more reliability than a few stitches.

Other uses include a clip in point for sleeping on a portaledge (particularly for stomach sleepers), a point to drag a sled (like the approach to Denali), and it also has some rescue purposes (like guiding longline cables in a helicopter, or belayed from rear while waist deep in swiftwater)

1. I am a supporter, intuitively, of having full-strength haul-loops on one's harness. (I am pretty sure the one on mine is).

2. csproul's justification was weak.

3. the reaons you cite make sense and bring up some applications that I hadn't thought of. thank you.
