Attic shelves are simple shelves that fully utilize the upper space of a warehouse. Build a middle attic on an existing shelf or workspace to increase storage area. Light foam, small and medium-sized goods, or goods with a long storage period can generally be placed on the attic floor. Forklifts, conveyor belts, elevators, electric hoists, or lifting platforms can be used to lift the goods. Lightweight carts or pallet towing carts are generally used for operations in the attic.
