Abstract
A method for detecting degradation of resin film detects whether a resin coated rope having a circumferential portion coated with resin film has the resin film degraded. The method for detecting degradation of resin film includes: winding a wire on a circumferential portion of the resin coated rope; applying tension to the wire to compress the resin film in a radial direction of the resin coated rope; and comparing a first relationship with a second relationship to determine how the resin film is degraded, the first relationship indicating a relationship between the tension of the wire and how much amount the resin film has compressed, as obtained in the applying, the second relationship indicating a relationship between the tension of the wire and how much amount the resin film has compressed, as predetermined as a reference.
