Abstract
A communication link arrangement for a cargo moving device comprises an electrical infrastructure that is mechanically coupled to a cargo moving device. The cargo moving device includes a cargo retaining structure and a main body coupled to the cargo retaining structure. The electrical infrastructure includes a single conductor electrically coupling the cargo retaining structure and the main body for delivering power and data signals between the cargo retaining structure and the main body. The electrical infrastructure further includes one or more conductors. A first networking element is mechanically coupled to the cargo retaining structure and is electrically coupled to the single conductor. A second networking element is mechanically coupled the main body and is also electrically coupled to the single conductor. A high-speed network link over power line carries data over the single conductor in the electrical infrastructure that supplies power between the main body and the cargo retaining structure.
