Abstract: An apparatus and method for determining elongation of suspension members in 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. A first sensor detects a presence of one of the counterweight and elevator car, and a second sensor determines a position of the other of the elevator car and counterweight within the hoistway in response to a detection signal generated by the first sensor. Elongation of the at least one suspension member is determined based on a change in the position of the elevator car or counterweight in the hoistway over time as determined in response to the detection signal.

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 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.
