Is the axle on a ropeman mk1/2 strong enough for the decice to be used as an autolock pulley? I have just set this up as for crevasse rescue, and as you would normally either have to have a prussik on the krab that the rescuee is hanging on or use a microtraxion, can you not simple rig it up so the rope travels up around and down through a rope man, turning it into an autolock 'pulley' (though I am aware it does not have the friction reducing advantage of actually having a rotating wheel there).

There is a picture here if you want to see what I mean. https://www.dropbox.com/s/vzn5da8r3zbrk1w/2013-04-17%2014.16.57.jpg

In reply to Harry Martin: How you have it in the photo is fine, that's how I'd do it. Somewhere on wild country's website is the safe working loads for the ropemen etc. can't remember where now.

Just get one of these http://www.climbingtechnology.it/en-US/climbing/use-rope/rollnlock.html?idproduct=989
The roller is inside the toothed cam so works for hauling and its beautifully made.

Do cams that don't have sharp teeth work well on frozen ropes?


I have a micro, wonderful device. High efficiency pulley, more reliable that the minitrax.

In reply to needvert: Not sure about rope man 1 vs 2 on frozen ropes, i would imagine they would absolutely fine, as even though a frozen rope is hard, the surface is still rough and would engage the cam.
