Snaphook Comparison Drop Tests Video
ANSI Z359.1-1992 (R 1999) was the benchmark standard for connecting hardware until November of 2007 when significant revisions mandating stronger gates were adopted by ANSI. This 2-minute video features drop tests comparing snaphooks designed according to the 1992 standard to those designed according to the 2007 standard.

Articulated Mannequin Drop Tests Video
This 2-minute video features a series of drop tests using a 200 lb articulated mannequin fitted with a personal fall arrest system. During each drop test, the mannequin's fall is arrested with a different system including energy absorbing lanyards, self-retracting lifelines, Y lanyards and twisted rope. Each test reveals the maximum arrest force on the mannequin along with free fall distance and deployment distance. A drop test into a waist belt also shows the dangers of using this illegal body holding device. These tests prove the effectiveness and ineffectiveness of these fall arrest components to keep maximum arrest forces below injury levels.
These tests are not intended for analysis. They are a visual training aid to show what happens when fall arrest components are used correctly and incorrectly. Call Gravitec at 1.800.755.8455 if you have applications that require further analysis.

ANSI/ASSE Z359.13-2009 is one of three new standards released in the summer of 2009 for inclusion in the growing ANSI/ASSE Z359 Fall Protection Code, a series of voluntary fall protetion standards. Although ANSI is not law, its designation is highly regarded among industry professionals.
