The entire wall, 100' tall x 30' wide by who knows how thick moved an inch or so. We also had the block on top of Arrowhead rock on us as we were on it. We pr...

The ASCA says from testing that a toprope fall can generate 1,000 lbs force in the anchors based on testing they did. link below: http://www.safeclimbing.org/education/fallforces.htm I agree most bolts will be fine and rarely fatigue fail but the one I showed did fatigue crack and fail with little n...

A fatigue failure is the result of many smaller load cycles vs one larger load. The shown photo was the result of the anchor sticking out just a little too far from the rock resulting in a bending moment in the bolt instead of mostly shear with most bolts. Bolts are great in shear but not nearly as ...

How many high load cycles does it take to fatigue fail a bolt or hanger? 100 Whipper Snappers, 1000, 10,000? I guess it depends if it gets plastic or remains elastic.
