Last In - First Out: Principle
In LIFO configuration (Last In - First Out), a forklift truck loads and unloads the pallets at the picking face. This is a pushback system. To load a pallet, the forklift truck pushes the pallet at the picking face towards the back of the lane using the pallet to be loaded.
When a pallet is unloaded, the pallet stored behind automatically takes its place, thereby ensuring that the goods are constantly available at the picking face.
