Abstract
An elevator support monitoring device in an elevator system and a method for monitoring the elevator support means monitor a characterizing property, preferably an electrical resistance, of the elevator support or of a tension support of the elevator support and a sudden change in the characterizing property is detected. A state of the elevator support is determined by evaluating several consecutive, sudden changes in the characterizing property.

1-17. (canceled)
A method of monitoring an elevator support comprising the steps of:
- monitoring at least one characterizing property of the elevator support with an elevator support monitoring device connected with the elevator support;
- detecting an abrupt change in the at least one characterizing property with the elevator support monitoring device;
- and
- determining a state of the elevator support with the elevator support monitoring device by evaluation of a plurality of successive ones of the abrupt change in the characterizing property.
An elevator support monitoring device for monitoring an elevator support comprising:
- a connecting device connecting the elevator support monitoring device with an elevator support;
- and
- a device for detecting and evaluating a characterizing property of the elevator support or a tension carrier of the elevator support, the detecting and evaluating device detecting an abrupt change in the characterizing property and determining a state of the elevator support by evaluation of a plurality of successive ones of the abrupt change in the characterizing property.
