Abstract
A work machine, such as a hauler at a mining site, includes a conductor rod housing concentric metal tubes for receiving electrical power from a contactor sliding on a power rail. A head-end interface of the conductor rod proximate the work machine includes metallic rings spaced apart and extending circumferentially around the head-end interface. Bores pass longitudinally through the head-end interface and into cavities within the conductor rod between the concentric metal tubes. The metallic rings enable the delivery of electrical power radially from the conductor rod for powering the work machine, while the bores enable the delivery of pneumatic power longitudinally into the conductor rod for powering axial movement of the conductor rod.
