Abstract
Abstract A power supply chain comprises a plurality of power supply conduit carriers that include 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 low friction, 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 when in engagement with one or more power supply conduits, such as one or more cables, hoses, and the like, in the carrier.
