Abstract

A method determines a status of at least one component of an elevator system, wherein the elevator system includes a suspension apparatus having at least one traction member. The at least one traction member is surrounded by a non-metallic cladding, wherein the suspension apparatus is guided via a drive sheave with a metallic traction surface. The method includes the steps of: identifying at least one parameter based on an electrostatic effect which occurs due to friction of the non-metallic cladding on the traction sheave with the metallic traction surface; and determining a status of the at least one component on the basis of the identified parameter.
