  • Elevator installation
    Patent number: 9840397
    Abstract: An elevator installation has a car at least partially supported by a support including several electrically conductive tension-bearing elements, which elements are arranged parallel to each other and which are substantially surrounded by a jacket. The support is fastened to fastening devices, wherein the fastening devices each include a housing and a clamping element. The housing and the clamping element each have clamping surfaces, between which surfaces the support is clamped. An electrically insulating material is arranged between at least one side of the support and the clamping surfaces arranged thereon. The electrically insulating material electrically isolates the support from the housing or the clamping element or both.
