A tilting tray products sorting apparatus employing belt and/or driven rollers conveyors for traversing tilting tray carriages between loading and unloading stations. A latch member between the carriage carrying tray and base is pivotable between a latched position for maintaining the tray level, and an unlatched position for tilting the tray. Tipping elements at each unloading station are selectively extended for engaging and pivoting the latch member to its unlatched position and tipping the tray. The tipping tray center of gravity maintains the tray in its tipped position. Leveling arms adjacent the conveyor engage tipped trays for pivoting them back to a level position and thereby pivoting the latch member to its latched position. The carriages gravitationally rest on and frictionally engage the conveyor carrying and traversing surface. Side walls along the conveyor maintain the carriages on the conveyor carrying and traversing surface.
