A method and apparatus for stacking first and second loaded pallets includes a pallet stacker that defines a stationary stacking location. A first loaded pallet is conveyed to the stationary stacking location. In preferred form, plural sensors check the first loaded pallet for preferred load height and preferred load integrity. A pallet carriage vertically adjustable at the stationary stacking location then engages the first loaded pallet and moves it to a temporary holding position. A second loaded pallet is conveyed into vertical registration with the first loaded pallet. The plural sensors also check the second loaded pallet for preferred load height and preferred load integrity. The first loaded pallet is then vertically adjusted into stable stacked relation with the second loaded pallet, and the pallet carriage disengages the first loaded pallet. The first and second loaded pallets, in stable stacked relation to each other, thereafter are discharged from the stationary stacking location.
