Crevasse Rescue Z-Pulley 3-1 System

While waiting around I’ve been brushing up on crevasse rescue skills. I really enjoy the mechanical theory behind these systems and thought I would share a bit of it with you in case you ever need to pull someone out of a hole.

If you are lucky enough to have 5-6 people on the surface, you can drag out one climber. Fewer and you need a mechanical advantage system like this Z-Pulley 3-1 Mechanical Advantage system I improvised from the gear that I carry on my harness during alpine climbing.
