A method for operating a storage and retrieval unit (3) is specified, in which a rail line (1)/power-supply rail (6) is set to a risk-operation voltage when a risk posed by the storage and retrieval unit (3) is detected. In the storage and retrieval unit (3) the level of the voltage applied to the rail line (1)/power-supply rail (6) is measured and a current path between the rail line (1)/power-supply rail (6) and a drive motor (5, 5a . . . 5c) of the storage and retrieval unit (3) disconnected when the voltage measured is below a threshold value associated with a risk situation. Furthermore, a storage and retrieval unit (3) as well as an automated rack storage system for performing the proposed method is specified.

Provided is an electric vehicle in which the state of contact between an electric connection arm and an external power line can be stabilized during traveling of the electric vehicle. In the electric vehicle, when the free end of an electric connection arm contacts an external power line during traveling of the electric vehicle, a posture control device controls the posture of the vehicle body so that the rotation angle of the electric connection arm approaches a target rotation angle or a target rotation angle range.

A method for operating a current collector and a current collector are provided for transferring energy from a conductor rail to a rail vehicle. The current collector includes a contact pressing device having a sliding piece which forms a sliding contact surface. A contact pressing force acts on the sliding piece, as the sliding piece is moved relative to the conductor rail. The current collector further includes a measuring unit having a measuring device, at least one sensor of a sensing device of the measuring device being disposed on the contact pressing device and/or adjacent to the contact pressing device. A measured value of the contact pressing device is registered by means of the sensing device. The measured value is processed by a processing unit of the measuring device and a parameter describing an operating state of the current collector and/or the conductor rail is determined.
