Abstract

L'invention concerne un procédé et un dispositif de surveillance de moyens de support (27) servant à surveiller des propriétés d'un ensemble de moyens de support (9) dans un système d'ascenseur (1). L'ensemble de moyens de support (9) comporte plusieurs moyens de support (11), au moyen desquels une cabine (5) d'ascenseur est maintenue et doit être déplacée. Le procédé comprend une mesure de forces de traction agissant sur les moyens de support (11), et une déduction d'informations de modification, lesquelles indiquent des modifications effectuées pour les propriétés d'un ensemble de moyens de support (9) en analysant une évolution dans le temps des forces de traction mesurées. Une analyse de ce type tenant compte par exemple d'un gradient dans le temps, d'un spectre de fréquences et/ou d'une amplitude de l'évolution dans le temps des forces de traction mesurées permet de déduire par exemple des informations portant sur l'usure sur un profilage de surface (45) ou sur une face de traction (47) d'un galet de renvoi (17) ou d'une poulie motrice (15), des informations portant sur l'usure sur des rails de guidage (43) et/ou des informations portant sur l'usure de structures de guidage latéral (49) sur un galet (16) servant à guider un des moyens de support (11).
