ABSTRACT:
A power supply chain comprising a plurailty of power supply conduit carriers including first and second side links and first and second cross-pieces connected between the side links to form the carrier. The cross-pieces each comprise an elongated cross-piece member having a channel extending along the length of the member and a plurality of cylindrical rollers disposed end-to-end along the length of and residing in the channel for rotation in the channel relative to the cross-piece member. One or more roller separators are disposed transversely between facing cross-piece rollers in the cross-piece channels. Each roller separator typically includes an intermediate cylindrical roller region for engaging one or more power supply conduits and cylindrical end studs or shafts that are rotatably received in corresponding bores in the facing cross-piece rollers so that the separator roller can freely rotate on the cross-piece rollers.
