  • Publication number: 20240017963
    Abstract: 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.

  • Patent number: 11450455
    Abstract: An electrical cable for vertical applications includes a core having a length L, a sheath surrounding the core and extending through the whole length L and a reinforcing jacket surrounding the sheath and in direct contact therewith. The reinforcing jacket is made of concentric layers including a first layer longitudinally extending from a first cable end (the proximal or upper cable end, in use) towards a second cable end (the distal or lower cable end, in use) substantially along the whole length L. The reinforcing jacket also includes at least one further layer longitudinally extending from the first cable end towards the second cable end for a length shorter than L. At least one layer of the reinforcing jacket is a circumferentially closed metal tube.

  • Patent number: 7214882
    Abstract: A method, an extrusion apparatus and a plant for continuously manufacturing a communication cable. A plurality of twisted pairs of insulated conductors are housed in respective cavities longitudinally formed within an elongated integral body. The cavities have a substantially circular cross-section and maximum diameter adapted to prevent any relative movement of the twisted pairs of insulated conductors with respect to one another, while each of the pairs of insulated conductors is substantially free to move within the cavities along the longitudinal direction of the cable.
