Slow Pull Testing Basket Hitches Clipped to Themselves

We broke nine basket hitches clipped to themselves tied in 1" tubular nylon webbing , rotated around the anchor, and clipped with a 1/2" diameter screw link to:
1. Measure the breaking strength
2. Identify the failure location
Results:
1. The average breaking strength was 41.1 kN (9239 lbs)
2. The standard deviation was 2.6 kN (595 lbs)
3. The range of breaking strengths was 7.8 kN (1760 lbs)
4. All anchors broke at the screw link at the lower strand
The results will be presented at the International Technical Rescue Symposium 2015. The complete paper will be published in their research archives at:
