Bill,
Best way to move something of this size and weight by yourself, is take it a part. You'll learn a little about how it's put together. Still some of those parts are big and can hurt if they fall on you, so becareful and good luck.
Looks like you have a shorter stair case to go down than I did.
BTW, the I think the heaviest part is the base/column of the machine, next the ram and then the table.
Regards,
Bernd
