Patent number: 12103824Abstract: An elevator system includes a travelling cable connected to an elevator car and to a hoistway wall. The travelling cable includes an electric conductor and/or a data carrier operatively connected at a first end to a feed source and at a second end to service appliances of the elevator car. A protective layer includes an outer diameter and surrounds the electric conductor and/or data carrier. A duct is connected at a first open end to a fluid source and at a second openable end to the elevator car. A sensor system is configured for detecting swaying amplitude of the travelling cable. A microprocessor is associated to the sensor system and to the fluid source. The microprocessor is configured for receiving swaying amplitude data from the sensor system and for operating the fluid source when the swaying amplitude exceeds a predetermined threshold.Type: GrantFiled: July 14, 2023Date of Patent: October 1, 2024Assignee: Prysmian S.p.A.Inventors: Luca Giorgio Maria De Rai, Davide Sarchi
