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...
