Publication number: 20210387832Abstract: The invention concerns a method, system and computer program for monitoring the run of a roping interconnecting a car and a counterweight of an elevator and for detecting an abnormal operation condition during the drive of a traction sheave intending therewith the car and the counterweight to be moved via said roping. Said roping is running on its way from the car to the traction sheave via at least one pulley and on its way from the counterweight to the traction sheave via at least one pulley, wherein the rotation of said at least two pulleys is monitored by sensing their rotation. These rotation data are then analysed in view of a mutual correlation indicating therewith a synchronized run of the roping on either side of the traction sheave, and detecting therewith an abnormal situation when detecting an absence of such correlation.Type: ApplicationFiled: May 3, 2021Publication date: December 16, 2021Applicant: KONE CorporationInventors: Mikko Viljanen, Tarvo Viita-aho, Tapani Talonen, Matti Räsänen, Juha-Matti Aitamurto, Tapio Siironen, Ville Myyryläinen, Henri Wenlin
