A part conveyor includes a series of slide bars of equal lengths. Each bar is movable in a pair of parallel rails and in transfer rails at the ends of the parallel rails. The slide bars have upwardly opening U-shaped members projecting from the rails. A push rod simultaneously moves the slide bars through the rails to advance the bars. A cross rod rests in an aligned member for movement of the crossbar and part with the slide bars. A transfer rail unit is provided at the ends of each run for moving of the slide bars from the rails. In an over/under line, transfer rails receive and move the slide bars. A U-shaped carriage is mounted on vertically movable tracks for movement between and end of the rail run and a load source. The parallel rails drop below the top of the carriage sides and drops the cross rod onto the carriage. The carriage moves to a load source and the tracks are lowered to unload the cross rod and receive another cross rod. The tracks are raised and returned. When the rails move up, the slide bars pick up the new cross rod and places the load into the system.
