    Redirects in Rope Systems: Load Dissipation between Natural Anchor Points in Trees


    Redirects are used in work positioning by climbers or to design rigging systems. But the effect on branches as natural anchor points is not well understood. Redirects dissipate load within the crown. The loading experienced by the main anchor and the redirect point were measured during a study and visualized in diagrams. The presentation will point out differences in load dissipation during several climbing actions and quantify the loading of the anchor points. Arborists will gain better understanding of how the application of redirects can alter the loads anchor points are exposed to and thus may increase or decrease the likelihood of failure.
