PTPP's 2:1 in Climbing Mag
« on: October 15, 2012, 08:14:12 am »
I have a link to Pete's tech tip in Climbing Mag for a 2:1 here: http://www.climbing.com/skill/tech-tip-aid-2-1-hauling-ratchet/

The illustration for it does not show up on the link for me. Can anyone tell me if this is the illustration that is supposed to go with this article?:

Yes that is the correct illustration; with a couple of comments.

The "Frost Draw" may not be necessary, depends on the 'hauling device' you use.  If you need one you could always use a big wired nut.

If you have two different pulleys put the good one on top (ie. the upper/higher pulley).  It gets worked harder.

While on the subject, why a cable/Frost draw instead of tied cord (like Mark Hudon's system) or simply a draw with lockers on each end? Is this simply an issue of abrasion resistance or am I missing something?
Is this too long for the cable draw: http://www.climbtechgear.com/cable-dogbone/?

Any recommendations on pulleys for this system?

I don't think you are missing anything.  Best I can you just want something that allows freedom of movement and is relatively short.

Another good discussion on 2:1 :

I made Markn a custom swage in place of the frost draw/tied cord attachment for the upper pulley.

Wonder how that worked out?.......


I just hauled 400+ lbs with my partners 2:1 rig on my last wall.  I would say that having 2 of the same rescue style pulleys (sealed bearing), one on either end is the ticket.

The lower pulley damn near exploded by the end, I will have a sealed bearing style for the next wall.

I've got one of those so if we manage to finally get on the glass at some point you can check it out.  I don't have a lot to compare it to but it seems to get the job done.

I've never used that pulley.  But I like the price.

I have a couple of CMI RP103 pulleys, lighter but a lot more expensive.

But I will not use both for my 2:1.  I plan on using the Petzl Partner for the lower pulley.

So I suppose since the Camp pulley is significantly less money, it's wise to ask for feedback.

Looks like good specs. good value for that pulley. Ideal for 1:1. If you want to use it for 2:1 hauling, it will still work (as a separate component), but you won't be able to have a large carabiner "spanning" the pulley as Mark Hudon shows in his tips because of the cutout in the pulley side plates. Same deal with the CMI 103/104, etc.
