At least one group of at least three elongated slats are mounted side-by-side on a frame for longitudinal reciprocation to form a conveyor, the slats being connected to a fluid pressure drive mechanism which is operable to move all of the slats of each group from a start position simultaneously in a load-conveying direction and then to move the slats of each group sequentially in the opposite direction from the advanced position back to the start position, the slats of each group being interengaged releasably in the conveying direction to insure simultaneous movement.
