Abstract: A device and method for detection of wear of a sliding contact which may be displaced along a brushgear, includes a sensor and a measurement indicator designed for detection by the sensor. The sensor and the measurement indicator approach or move away from each other by a shortening of the sliding contact caused by wear, and a brushgear system. The problem of enabling simple, reliable detection of the practically complete wear of the sliding contact is addressed by the sensor being designed for contactless and/or contacting detection of the measurement indicator, and by means of a brushgear system having a device of this kind, and also a method of this kind in which the sensor detects the measurement indicator becoming closer to the sensor contactlessly and/or contactingly and, when a threshold value for a predetermined wear of the sliding contact is exceeded, issues a warning signal.

Abstract: A fastening device for fastening a conductor line to at least one mounting element. The fastening device has at least one holding element connectable to the conductor line. The holding element fastens the conductor line to the mounting element such that movement perpendicular to the longitudinal direction of the conductor line is not possible. A conductor line system has a conductor line, which is fastened by a first fastening device to a first mounting element and by a second fastening device spaced apart therefrom to a second mounting element. The first fastening device is connected to the conductor line and to the first mounting element in such a way that movement in the longitudinal direction is not possible. The second fastening device is connected to the conductor line and/or to the mounting line in such a way that movement in the longitudinal direction is possible.

Abstract: A current collector for electrically supplying an electrical load which is movable along a conductor line. The current collector has a fastening element and at least one sliding contact with an elongate sliding contact surface, which extends in a longitudinal direction, for sliding contact with an electrically conducting line profile, which extends in the longitudinal direction, of the conductor line. The sliding contact is articulated on the fastening element at spaced apart fastening regions, so as to be movable in a feeding plane extending parallel to the longitudinal direction by means of two articulated lever arrangements. A resetting device acting on the articulated lever arrangements and on the fastening element is provided which, when the sliding contact is deflected from an inoperative position, in which the sliding contact surface preferably extends substantially parallel to the longitudinal direction, moves the sliding contact back into the inoperative position.
