A current collector and a conductor line system having such a current collector. The current collector has a holder and a carbon brush arranged in carbon brush support movable relative to holder in a feed direction from and to the conductor line. The carbon brush is movable in a feed direction from and to conductor line. A better and reliable guiding of the carbon brush on the conductor line and simpler design of the current collector, uses a current collector in which the carbon brush is additionally movable in a transverse direction running essentially across the longitudinal direction, a spring element being provided between the carbon brush and holder.

System for electrically feeding electrically powered vehicles comprising at least one suspended elongated slotted element having electric conductor(s) arranged in slot(s) and at least one current collector co-acting with the slotted element. The current collector(s) comprises contact element(s) and collector arm(s) supporting the contact element(s) at its first end and is adapted to connect to an electrically powered vehicle with its second end. The collector arm(s) is formed by at least two serially arranged arm segments. A first arm segment is provided with forcing means arranged to, when the first arm segment is within a working distance from the slotted element, provide a force towards the slotted element such that the contact element connects with the corresponding electric conductor. The second arm segment is provided with at least one actuator acting on the second arm segment to displace the first arm segment to a position within the working distance.

During travel of the electric vehicle, the charging arm is extended in the vehicle width direction, a positive electrode overhead line of the power supply device and a positive electrode power reception unit of the charging arm are brought into contact at the same time that a negative electrode overhead line of the power supply device and a negative electrode power reception unit of the charging arm are brought into contact, and a power storage device for driving the electric vehicle is charged. A charging head that is the tip section of the charging arm is held within a V-shaped groove to which the positive electrode overhead line and the negative electrode overhead line are attached, thereby minimizing the loss of contact even if the charging arm shakes in the vertical direction as a result of the condition of the road surface, brake operation, or the like.

An overhead type transport apparatus includes: a guide rail that includes a main rail and one or more sub rails crossing the main rail and is fixed to a ceiling side; two or more transport units that travel along the guide rail; a carrier unit that is coupled to the bottom of each transport unit and rotates about a carrier rotating unit, one end being inclined upward or downward with respect to the other end; and a basket unit that is attached to and detached from the bottom of each carrier unit.

A quick charging system for electrically driven vehicles and method for forming an electrically conductive connection between a vehicle and a stationary charging station having a contact device, a charging contact device, and a positioning device. The charging contact device can be electrically contacted in a contact position together with the contact device. The contact device can be positioned in the vertical and horizontal direction relative to the charging contact device and moved to the contact position. The contact device has a contact element carrier with contact elements that can each be electrically contacted together with charge contact elements of the charge contact device, forming contact pairs, in the contact position. A guide device is provided, such that, when the contact device and the charge contact device are brought together, a physical contacting of the contact elements together with the charge contact device is inhibited before reaching the contact position.
