The illustrated invention is intended for use as an overhead crane rail that hangs via rollers on the turned-in lower edges of the side of the rail. A carriage from which a hook or grab hangs via a chain or cable that can be payed out or drawn in by a motor/transmission unit mounted on the carriage that itself can travel along the rail.
