Abstract
A method and a supporting-means monitoring device monitor properties of a supporting arrangement in an elevator system. The supporting arrangement has a plurality of supporting devices that support and can displace an elevator car. The method includes: measuring tensile forces acting on the supporting devices; and deriving change information indicating changes in the properties of the supporting arrangement by analyzing the progression over time of the measured tensile forces. By such an analysis, taking into consideration, for example, a temporal gradient, a frequency spectrum, and/or an amplitude of the progression over time of the measured tensile forces, there is derived e.g. information about wear on a surface profiling or a traction surface of a deflection roller or a traction sheave, information about wear on guide rails and/or information about wear of lateral guide structures on a roller for guiding one of the supporting devices.
