- A small rope team can use a pulley system to rescue a companion who has fallen into a crevasse on a high alpine tour.

For small rope teams (two or three people), the pulley system is used for rescuing partners. The pulley method halves the weight of the fall victim so that - in the best-case scenario - a strong partner can single-handedly haul a fall victim out. However, the technique calls for a number of items of equipment: sufficient spare rope, accessory cords, carabiners and a self-locking pulley.
A redirect pulley with reverse lock (such as Petzl’s Micro Traxion) reduces friction and will thus enable optimized force transmission - which makes hauling easier for two-man rope teams in particular.
With rope teams of four or more people, hauling is the quickest, simplest crevasse rescue method. Learn how in the next video: • Hauling: Crevasse resc...
Excellent production! lol also love the yolo jump into the crevasse
This channel is gold
Thanks for the great video.

How do rescue of sheepulle and zedpulle systems.
Hi Netai,
you can use pulleys for almost every rescue system when you need to redirect the rope or block the rope in one direction and be able to pull in the other. This - as mentioned - is almost always needed for the different rescue and hauling systems. The main advantages are the reduced friction and the much easier handling (compared to Prusik or Garda).
Hope this help!
Best, your ORTOVOX-Team
