Abstract:
A method for stacking loaded pallets one on top the other, said method comprising the steps oflocating a first pallet having a first load in an entry position at a stationary stacking work station, engaging a pallet carriage in operational relation with said first pallet at said entry position of said work station, the height of said carriage and therefore of that first pallet carried thereby, being vertically adjustable, moving said first loaded pallet in a vertical direction relative to said entry position by use of said pallet carriage to a temporary holding position in said work station that is different from said entry position, locating a second pallet having a second load in said entry position of said stationary work station, moving said first loaded pallet in a reverse vertical direction relative to said entry position into a stacked relation with said second loaded pallet in said work station, and sensing the preferred load integrity of that load on which said first loaded pallet will rest prior to moving said first loaded pallet into stacked relation with said second loaded pallet so that first and second loaded pallets will be stacked in stable relation one with the other.
