Abstract
Disclosed are methods and apparatuses for analysis of synthetic ropes, cords, slings, cables and belts (collectively termed “ropes”) including but not limited to ropes for bearing loads as well as fiber optic cables. The ropes are provided with one or more elements for magnetic detection, wherein the magnetic detection elements each comprise a metal fiber or an appropriately treated synthetic fiber. The methods and apparatuses encompass detection of induced or residual magnetism or magnetic flux in the magnetic detection element(s), to sense for example lay length and/or damage, breakage or wear of the magnetic detection element(s), indicative of the condition of the rope.
