Breaking-Load Evaluation of Modified Navy Crane Insulator Links.

reportActive / Technical Report | Accession Number: ADA099579 | Open PDF

Abstract:

An earlier study by NRL found that the 15 long ton Navy insulator link, as manufactured in accordance with MIL-L-24410 SHIPS, was not fail-safe at crane loads of six times the rated load. This report presents results on breaking loads for a series of modified Navy links. Recommendations are presented to either change the present MIL SPEC to achieve fail-safe design or to abandon the redundant band concept and increase the safety factor on crane insulator links.
