A palletiser and depalletiser apparatus for respectively adding or removing product, stackable in layers on a pallet, to or from the pallet by layer is provided with first, second, third and fourth gripper assemblies (100, 200, 300, 400). Each gripper assembly has a gripper surface (101, 201, 301, 401) for gripping a corresponding side of the product layer. The first and second gripper surfaces (101, 201) are opposing and mutually parallel and are disposed perpendicularly to the third and fourth gripper surfaces (301, 401) which are also opposing and mutually parallel. The gripper assemblies (100, 200, 300, 400) are mounted on a frame (500), each gripper assembly being mounted for horizontal displacement in a direction of travel perpendicular to its respective gripper surface (101, 201, 301, 401). The frame (500) itself is also vertically displaceable.
