FIELD: transport.
SUBSTANCE: invention relates to elevator drive element state monitoring. Proposed method consists in that selected electric signal is applied to tensioned element. Tensioned element electric parametres is controlled. Electric parametre allows defining the presence of localised strain or deteriorated state of tensioned element. Proposed device incorporates controller arranged to selectively apply electric signal to tensioned element. Electric signal consists of a group of pulses with pulse duty factor making less than 10%. Proposed assembly comprises a group of electrically conducting elements, non-conducting sheath and aforesaid controller.
EFFECT: efficient monitoring of elevator traction elements.
