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