LEADING EDGE SELF RETRACTING LIFELINES<\/strong><\/span><\/h2>

An Effective Alternative To Steel Cables<\/strong><\/span><\/h3><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

INTRODUCTION<\/span><\/strong><\/h2>

Leading Edge Self Retracting Lifelines have traditionally been designed with heavy steel cables as it was a proven product that could pass the ANSI\/ASSP Z359.14-2014 Standard. Until recently there were no alternate materials that could be used to pass this rigorous test which requires connecting a 282 lb. test mass to the SRL and dropping it perpendicularly and offset over a .005\u201d radius steel edge. The test mass must swing unrestricted on the edge for 2 minutes to verify it will not separate and cause the weight to break free. After the two minute period, the sample must then be tensile tested and maintain a breaking strength greater than 1,000 lbs. An alternate method to not tensile test the sample after the 2 minutes is to substitute a 300 lb. test mass in place of the 282 lb. test mass.<\/p><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

STATEMENT OF PROBLEM<\/span><\/strong><\/h3><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

When a new product is introduced to an alternative time-tested product, there can be questions and skepticism as to how it will perform. This is especially true when the product you are developing is a critical lifesaving component in the fall protection industry. Even with the various standards that are put in place to protect workers, it is important to continuously test the product to meet and exceed those standards by testing above and beyond what a standard requires. Additionally, most standards call for products to be tested in a \u201cnew\u201d condition vs. being tested what might be a \u201cused\u201d product in the field. If a product has been in the field and used over a period of time, will it still perform as intended? To address this, Sturges utilized one of its drop towers to see the effects of how a webbing leading edge lifeline would perform.<\/p><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
