Choosing an appropriate tie-in point (TIP) is a key to efficiently and safely work in a tree. A TIP that’s high and central in the crown provides maximum mobility for a climber, but the TIP also has to be strong enough to bear the loads associated with climbing. Until recently, very few measurements of such loads were taken. Starting with the ITCC in 2017, Dr. Kane has measured loads at the TIP for a variety of situations including ascents, descents, limb walks and swings, and falls. This presentation will present the findings from those studies.
