Relocatable base for elevated power rails and method of deployment
ActiveUS12391149B2Power railsPropulsion by batteries/cellsStructural engineeringMechanical engineering
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.

System and method for joining power rail segments
A modular structure supports elevated rail segments for delivering electrical power to a moving work machine, such as a hauler at a mining site. End portions of rail segments having narrower widths than body portions of the rail segments are joined within a split fishplate. Laterally opposing faces within the narrowed end portions form a longitudinal overlap, and connectors underneath the rail segments pull the split fishplate together against the end portions. In arrangements with parallel rails around a curvature, the rail segments are adjusted by sliding so that the longitudinal overlap is larger for rails on an inside of the curvature compared with rails on an outside of the curvature.
