Patent ID: 8360208

Claim:
A synthetic fiber rope for supporting an elevator car in an elevator installation, said synthetic fiber rope having a plurality of strands that are arranged in at least one strand layer, the strands being formed of twisted yarns and the yarns being formed of synthetic fibers, comprising: at least one of the strands in the at least one strand layer being an indicator strand including at least one indicator fiber or at least one indicator yarn, said at least one indicator yarn including indicator fibers and synthetic fibers, said at least one indicator fiber or said at least one indicator yarn being positioned internal of said indicator strand and participating in a spiral structure of the synthetic fibers or of the synthetic fiber yarn; at least another strand of the plurality of strands not including either of an indicator fiber or an indicator yarn, wherein said indicator strand is inferior to said another strand in relation to applied stress for monitoring a rope service life of said synthetic fiber rope when supporting said elevator car in said elevator installation wherein the synthetic fibers forming said indicator strand have a reverse bending capacity inferior to a reverse bending capacity of the synthetic fibers forming said another strand.
