A reciprocating slat conveyor, comprising: framework providing a support for fixed and movable conveyor slats, said framework defining a window sized to receive three transverse drive members and allow said drive members to reciprocate in the window longitudinally of the conveyor; three transverse drive members in said window; laterally spaced apart fixed slats, extending longitudinally of the conveyor and supported on the framework both forwardly and rearwardly of the window; said fixed slats extending longitudinally over the window; said fixed slats supporting elongated bearings that extend length wise of the slats substantially throughout the full length of the slats; laterally spaced apart movable conveyor slats extending longitudinally of the conveyor between the fixed slats, said movable conveyor slats being divided into sets, one set for each transverse drive member; wherein each set of movable conveyor slats is connected to a related one of the transverse drive members, so that each set of slats will move with its transverse drive member; said movable slats having portions that rest on the bearings so that during longitudinal movement of the movable slats said slats will move on the bearings; wherein the fixed slats are longitudinal beams having laterally spaced apart side parts and a top wall connected to the side walls; wherein the fixed conveyor slats are box beams having spaced apart side walls, a top and a bottom spaced below the top and extending between the side walls; and wherein the movable conveyor slats comprise longitudinal box beams that are disposed between the fixed conveyor slats, said box beams having spaced apart sidewalls, a top and a bottom spaced below the top and extending between the sidewalls.
