A flexible rail according to one preferred embodiment of the invention comprises (a) hollow rail pieces each having a generally inverted U-shaped vertical cross section, opposed open ends, a pair of laterally opposed bottom portions for supporting rollers of a roller chain, and a bottom space located between the opposed bottom portions from which hangers may be hung from the roller chain, (b) a pair of laterally opposed side plates fixed to the respective side walls of each rail piece such that the side plates overlap the side walls, (c) a pair of laterally opposed connecting plates each associated with adjacent side plates on one of opposed sides, each of the connecting plates overlapping both of the adjacent side plates, but being fixed to only a rear one thereof, and (d) a pair of pivotal means provided in conjunction with the opposed side plates, respectively, and each connecting a front one of adjacent side plates on one of the opposed sides and a connecting plate on the same side for pivotal movements about a common axis. The flexible rail may be used to provide a flexible conveyor. Also, the flexible rail may be used to provide a flexible trolley conveyor for an electrodeposition coating system.
