Abstract
Roundslings with radio frequency identification pre-failure warning indicators comprise radio frequency identification tags, radio frequency identification tag sensors, and radio frequency signal receivers that inform a user of a pre-failure condition with the roundsling. The radio frequency tags may be affixed to one or more of an indicator yarn, a strand of the roundsling core, a dedicated strand of a pre-failure indicator assembly, or a ring of the pre-failure indicator assembly. The radio frequency tags may be active or passive, and active radio frequency tags may comprise a shield that block a signal transmitted from the tag.
