Abstract: A cart loading conveyor for receiving palletized cartons at one level from a pallet loader and for lowering the same to the flat bed surface of a cart, truck and the like for deposit thereon in a manner avoiding tilting of the interlocked stack of cartons on the pallet during skidding of the pallet onto the flat bed of such truck. A discharge conveyor having a tunnel-like cart receiving zone beneath a pallet support plate arranged for up and down movement between a level for receiving units of palletized cartons at higher level and for lowering the latter vertically to the level of the top surface of the flat bed of such cart whereby a unit of palletized cartons discharging from the support plate is transferred to such cart in a non-tilted condition similtaneously with the moving of the cart out of such tunnel-like zone.
