Elevator system

A method for operating an elevator system, the method comprising:

• providing an elevator car in a hoistway having at least one wall;
• providing a feed source and a fluid source associated with a hoistway wall;
• providing a travelling cable connected to the elevator car and to the hoistway wall, wherein the travelling cable comprises:
• an electric conductor and/or data carrier operatively connected at a first end to the feed source and at a second end to a service appliance of the elevator car, a protective layer surrounding the electric conductor and/or data carrier, and a duct connected at a first open end to the fluid source and at a second openable end to the elevator car;
• providing a sensor system associated to the elevator car and/or to the hoistway;
• providing a microprocessor associated to the sensor system and to the fluid source;
• setting a threshold for a swaying amplitude of the travelling cable;
• detecting, by the sensor system, the swaying amplitude of the travelling cable during the operation of the elevator system;
• sending data relating the swaying amplitude detected at the sensor system to the microprocessor;
• and
• at the crossing of the threshold, operating the fluid source to pressurize the duct of the travelling cable until the swaying amplitude of the travelling cable returns below the threshold, wherein swaying of the travelling cable is damped by the operating.

An elevator system comprising:

• a travelling cable connected to an elevator car and to a hoistway wall, wherein the travelling cable comprises
• 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 comprising an outer diameter and surrounding the electric conductor and/or data carrier, and
• a duct connected at a first open end to a fluid source and at a second openable end to the elevator car;
• a sensor system configured for detecting swaying amplitude of the travelling cable;
• and
• a microprocessor associated to the sensor system and to the fluid source, the microprocessor being configured for receiving swaying amplitude data from the sensor system and for operating the fluid source when the swaying amplitude exceeds a predetermined threshold.
