  • Publication number: 20250179739
    Abstract: A conducting rail retention system includes a plurality of conducting rails and a rail support assembly. The rail support assembly includes a support pole, the support pole including a top end and a bottom end, a support plate, the support plate being attached to the top end of the support pole, the support plate including a rail support portion on a top surface of the support plate, and a pair of rail clamps movable relative to one another from a rail unlock position to a rail interlock position securing the plurality of conducting rails to the support assembly.

  • Publication number: 20240157851
    Abstract: Dynamic energy transfer (DET) systems are costly and time-consuming to install. Accordingly, an installation system is disclosed that comprises stowage for rail segments and poles, two strategically positioned cranes, and/or strategically positioned platforms, to enable less expensive and faster installation of the various components of a DET system. Installation, utilizing the installation system, can significantly decrease the cost of installation, while increasing the rate of installation and maintaining safety.

  • Publication number: 20240006835
    Abstract: A slidable current collector has an array of terminals with carbon brushes for contacting conductor rails to deliver electrical power to a moving work machine. The terminals have upper sections with a conductive post, lower sections that include a reservoir of liquid metal, and bladders that connect the upper sections with the lower sections. Magnets surround outer shells of the terminals. Fluid above a threshold pressure fed into the bladders holds the upper sections apart from the lower sections and forces the magnets away from the conductor rails. Fluid below the threshold pressure allows the magnets to clamp the terminals to the conductor, lowers the conductive post into the liquid metal, and urges the carbon brushes against the conductor rails. The bladders provide a fluid suspension distributed across the array of terminals, enabling consistent electrical contact and wear for the carbon brushes.
