A fastening system for lift shaft information transmitters includes multiple carriers to support shaft information transmitters in different height positions for each story upon cables stretched over the entire height of the shaft. A respective bracket arranged at a guide rail may be provided at each of the lower and upper shaft ends. Tension springs, which are connected at one end each with a respective shackle, are connected at cable thimbles of the lower cable ends. The cable can be prestressed by the shackle arranged at the lower bracket. In an illustrative embodiment, three cables are provided, wherein the middle cable is slightly displaced relative to the outer cables towards the rear in the depth of the shaft and the outer cables are slightly displaced inwardly in the width of the carrier. For larger lift installations, a retaining rail, which is arranged at the guide rail and by means of which the cables are held fast, may be provided for each three to four storys. The retaining rail damps cable oscillations. |
