Elevator Traction Media Monitoring

An elevator system, comprising:

• an elevator car;
• a counterweight;
• and
• at least one traction medium connecting the elevator car and the counterweight;
• wherein the elevator system determines a position of the elevator car and the counterweight within an elevator shaft;
• wherein the position is an absolute position of at least one of the elevator car and the counterweight within the elevator shaft;
• wherein the absolute position is determined when the elevator car and the counterweight are determined to be in a defined position within the elevator shaft relative to one another;
• and
• wherein an absolute length and/or a relative elongation of the traction medium is determined from the absolute position.

A method of monitoring a traction medium of an elevator system, the method comprising:

• providing an elevator system, the elevator system comprising:
• an elevator car;
• a counterweight;
• and
• at least one traction medium connecting the elevator car and the counterweight;
• determining a position of the elevator car and the counterweight within an elevator shaft, wherein the position is an absolute position of at least one of the elevator car and the counterweight within the elevator shaft,
• determining that the elevator car and the counterweight are in a defined position within the elevator shaft relative to one another;
• and
• determining an absolute length and/or a relative elongation of the traction medium from the absolute position.
