set up a haul system with a grigri and a friction knot or just 2 friction knot. this way its easier to pull up and you have no teeth digging into your rope. if you want you can use the mini traxion as a friction knot and it won't dig into your rope as much as using it as the beley device

I'd say not such a good idea, because it will be harder to lower them if they give up. It is also not that easy to haul somebody up, unless they are pretty light. Better is a grigri or similar, so they can rest on the rope and then make progress themselves. Even better is to choose a climb that is not so hard for them, or one which you can clean on rappel if they can't make it up.

Lemme re-state your question.... "Is it safe to belay a second with a device not designed for belaying a second?" dev

I think that it would work, but is not the ideal device. ie, lowering, teeth, etc.

Let's see Reverso: $26.95 weight 81g Black Diamond ATC Guide: $25.95 weight 102g Trango B-52: $24.95 60g Mini Traxion : $69 weight 165 g, workin load as a pulley 2kn(~450 pounds), breaking strength as a pulley 6.6kn(~1485 pounds) If you use the Mini Traxion to belay a second you will load it over the roller the same way you would as if you were using it as a pulley. Pretty low breaking strength. Also it weighs more costs more and has teeth.

is it just me or is an ATC Guide a bitch to pull up slack on? It was difficult to feed and twisted the crap out of my rope when i used it...

Maybe i should restate. "Hauling" the second with mini traxion. Anybody?

I would still be worried about the strength issue. The mini traxion is not made for hauling a person. I think what you should look at is pettzl's I'D. It works like the GriGri but has an anti panic function that will make for better braking while still letting you release it. So my answer is no. use the right tool for the job.

i'd still use a grigri or two friction knots due to the teeth, but it won't kill your rope immediately....

its really easy to set up a belay device that is it autoblock mode to haul the second. all you need is a prussik and a locker. set the prussik up as low as you can reach on the end that is going to your second. take the brake end and clip it to the locker. you should be able to pull up on the tail of your brake end and it will haul your second and automattically lock off. if this doesn't make sense i can try to draw it or something to explain it better. but i promise it works. -aaron

Rasta, read what folks said and then do a search. Pass the Pitons Pete has had a total failure while hauling a load, claims thay are sh*t and will NEVER use one for hauling again. EVER. Tom who posts on this site has had the same thing happen. So it won't be me you are doing this to if thats one of the questions:-)

How many different ways do how many different people need to say it. Everyone has already listed all of the negatives -- expensive, heavy, and uhhhhh..oh...NOT SAFE. I'd go with a gri gri if you already own one and insist on using an auto locking device. Ed

On paper, this looks wonderful. The Reverso/ATCG is already in place, making this a quick fix. But last fall two friends and I spent a day at Mt. Erie, Washington, testing out some of these rescue ideas, including this one. Using this system, we discovered that the amount of force needed to raise the victim 1 meter without their assistance "felt" equal or greater to a 2:1 haul system. We agreed that a 3:1 built in this manner has so much friction built in - especially at the ratchet point (ATC/Reverso) - that most mechanical advantage is lost. We concluded that it was only slightly slower, but easier on our arms - to "piggyback" a haul system onto the climbers strand, raise the victim 1 meter, and disconnect the haul system. The advantages were 1) the Reverso/ATCG could be used continuously as a belay/backup and 2) once built, the haul system left hanging from the anchor to be re-used if the climber needed further assistance.

It didn't feel much different from "bro-hauling" to us. But we could have been weak!

Honestly.. if you're having to "haul" your second up the pitch, it would probably be more enjoyable to get on an easier route. If your second is having trouble with one or two relativly short sections, you can usually put something together between climber and belayer. If not, see first suggestion. :)
