That is the only problem with the 747 Freighter, you can put long low heavy loads in through the nose like, steal beams, pipping, rockets, some speed boats, and things like that. But you can't put a container off of semi/lorry through the front it is limited to going in through the back because of height, but is limited in the back do to width.
