Vibration stabiliser of an information carrier

A device (3), in particular a vibration stabiliser, for a lift system (2) functions to retain an information carrier (4) extending through a lift shaft (6) of the lift system (2) at at least one point (8) of the information carrier (4). A retaining element (15) and a clamping element (16) are also provided. The clamping element (16) can be connected to the information carrier (4) at the point (8) of the information carrier (4) preferably by means of a clamping force transmission means (17). The clamping element (16) can be clamped such that the information carrier (4) can be applied with a clamping force (F) preferably via the clamping force transmission means (17) against at least one contact region (38, 39) provided on the retaining element (15). The retaining element (15) can be positioned stationarily in the lift shaft (6). A device (3) having a magnet element (71) is also proposed. In addition, a shaft information system (1) for a lift system (2) having a device (3) of this type, a method for preventing vibrations of an information carrier (4) of a lift system (2) with at least a device (3) of this type, and an assembly method for assembling a device (3) of this type are also provided.
