Abstract
A method monitors at least one suspension apparatus in an elevator system, wherein the suspension apparatus includes at least one electrically conducting tension load carrying member that is surrounded by an electrically insulating jacket. The method includes the steps of: repeated determination of a value of an electrical characteristic of at least one tension load carrying member or of a group of tension load carrying members; establishment of a mean value on the basis of the determined values; and comparison of the mean value established with a reference value.
