Abstract:
A method for checking the integrity of a load bearing member of an elevator including tensile elements encapsulated in a case includes the steps of launching a source pulse through tensile elements of said load bearing member and comparing the feedback of said tensile elements with a comparator; tensile elements can be bridged to avoid a blind zone.
