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.

Abstract: A modular structure supports elevated rail segments for delivering electrical power to a moving work machine, such as a hauler at a mining site. Opposite ends of a roadside barrier contain complementary tubular couplers arranged vertically. A lower end of a dielectric post positioned in one of the tubular couplers has opposing dielectric plates at an upper end. A top edge of each plate has a creepage concavity between a pair of rail recesses. Another dielectric post of similar configuration is positioned in the other of the tubular couplers. Holes within the couplers and the posts ensure alignment of respective rail recesses in which conductive rails are placed. Dielectric inserts frictionally lock the rails into the rail recesses.

Abstract: A modular structure supports elevated rail segments for delivering electrical power to a moving work machine, such as a hauler at a mining site. Opposite ends of a roadside barrier contain complementary tubular couplers arranged vertically, one having a first diameter supported by an arm and the other having a larger second diameter and a vertical slot. Couplers on adjacent barriers can be mated together concentrically along a central axis. The mated couplers help restrict longitudinal displacement, lateral displacement, slope change, and lateral rotation between adjacent barriers during placement. One barrier may be used as a temporary alignment structure to position barriers spaced alternatingly along a haul route for the work machine.
