Abstract
An apparatus and method for an elevator system includes an elevator car that is supported for movement within a hoistway by at least one suspension member and a counterweight that is coupled to the elevator car with the at least one suspension member. The at least one suspension member is supported on a machine sheave at a location between the elevator car and the counterweight. The system detects a presence of one of the counterweight or elevator car as an initial detection, and subsequently detects a presence of the other of the counterweight or the elevator car as a subsequent detection. The system then determines an amount of travel of the elevator car that occurs between the initial detection and the subsequent detection to determine an amount of elongation of the at least one suspension member.
