Abstract: A method of monitoring a suspension member of an elevator system includes determining a condition of the suspension member based on a combination of an electrical inspection technique, a use indicator corresponding to an amount of use of the suspension member, and a mechanical characteristic indicator corresponding to at least one mechanical characteristic of the suspension member. The suspension member is removed from service based on an indication from the electrical inspection technique, the mechanical characteristic indicator, and the use indicator satisfying at least one predetermined combination of criteria.
