SYSTEM AND METHOD FOR JOINING POWER RAIL SEGMENTS

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. End portions (1106, 1108) of rail segments having narrower widths than body portions of the rail segments (240) are joined within a split fishp...

Summary: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. End portions (1106, 1108) of rail segments having narrower widths than body portions of the rail segments (240) are joined within a split fishplate (1102). Laterally opposing faces (1110, 1112) within the narrowed end portions (1106, 1108) form a longitudinal overlap (1202), and connectors (1134) underneath the rail segments pull the split fishplate together against the end portions. In arrangements with parallel rails around a curvature, the rail segments (240) are adjusted by sliding so that the longitudinal overlap (1202, 1206) is larger for rails on an inside of the curvature compared with rails on an outside of the curvature.
