Relocatable base for elevated power rails and method of deployment

Abstract

A modular structure supports elevated rail segments (240) for delivering electrical power to a moving work machine (100), such as a hauler at a mining site. Opposite ends of a roadside barrier (204) contain complementary tubular couplers arranged vertically, one (216) having a first diameter supported by an arm (110) and the other (218) having a larger second diameter and a vertical slot. Couplers on adjacent barriers (204-1, 204-0) 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 (204 0) to position barriers spaced alternatingly along a haul route (101) for the work machine (100).
