A grab (17), (64) assumes almost any position in space land is operated, via a direct electronic control device, by a computer. Data is typed into the computer which defines the sizes and position of both the objects (22), (62) and the loading structure (20) and the best, or preferred, positions of the objects (22), (62) and the structures (20).
