• the present invention relates to a power and / or data transmission system using a pickup truck, a route and a vehicle, wherein the vehicle is in particular a container stacker crane.
• the RTGs switch to their "diesel drive." Once they have entered an alleyway, the driver notifies the assistant that the cable of the pantograph vehicle is to be plugged into an RTG socket Trolley with chains attached to the RTG so that RTG moves the trolley over the chains and not over the electric cable.
• a disadvantage of the system described above is that the assistants manually move the container stacking crane (RTG) by means of the
• Object of the present invention is to facilitate the manufacture of the electrical connection between a vehicle, in particular a container stacking crane, and the route, in particular to automate.
• This object is achieved with a current collector system having the features of patent claim 1.

• the inventive pantograph system is not generally suitable only for container stacking cranes, but also for any vehicles, which must be moved along corresponding routes and supplied with electrical energy and / or data.
• the basic idea of the invention is that an automatic contacting of the vehicle with the at least one busbar routed along the route is possible by means of the current collector system.
• the difficulty is to compensate for the enormous tolerances by an automatic process. These tolerances result from a rather inaccurate distance position of the vehicle, in particular crane, to the busbar system in the horizontal and vertical directions.
• the pickup carriage is aligned by means of a positioning and introduction device relative to the busbar and introduced into this with its current collectors.
• the vehicle advantageously has an arm or another adjusting device, by means of which the pickup trolley is adjustable in the horizontal direction.
• the route has a contact plate against which the arm end, the adjusting device or the pickup trolley can be moved by means of a drive.
• the arm end can be provided for this purpose with at least one pressure roller or roller.
• the vehicle For retracting the pickup carriage into the mounting rails arranged on the route, the vehicle must therefore be moved with its pickup vehicle in front of the positioning and insertion device, after which the pickup carriage is moved by means of a drive in the direction of the contact plate is moved until it comes to a contact with the contact plate.
• the abutment plate which can be determined in particular by means of sensors or via the drive current of the drive, which adjusts the trolley in a horizontal direction, the trolley is aligned horizontally. Now can be retracted by moving the vehicle of the pickup truck in the introduction device.

• the pickup truck has rollers which rest on the running surface of the obliquely arranged rails, which raises the pickup truck as the vehicle moves on. In this case, either the entire arm with the pickup truck located thereon or only the pickup truck can be raised. In the simplest case, only the pickup truck is raised.
