Beschreibung:
Petzl partnered with the "Ice Climbing Ecrins" event to organize a workshop to test the pull-out strength of ice screws and ice threads. Petzl built a mini test center on a frozen creek in the Fournel valley. The pull-out strength was tested using an equalized belay anchor attached to a jack and a chain. Ice screws, ice threads and ice axes were attached to the system and pull tested. The pull-out strength was measured using a dynamometer. The results varied a great deal depending on the quality of the ice. The workshop took place over two consecutive days and the results were quite different from one day to the next. Despite this, the tests showed that ice screws were on average twice as strong as ice threads.
