My father had a piano shop. When I was about six years old I used to help him with deliveries. Just the two of us could move any upright piano almost anywhere. The secret is to use a piano trolley. I have one you could borrow, but it is in Northampton.
If it's a very old one, make sure it has a metal sound board not wood.
I think you meant wooded frame, as far as I know the sound board is always wood.
It's free, and I can't get a look-see first.
Googling on weights brings up a range of 300-500lb. If 300lb, I can shift it myself up and down a few steps. If it's more than that I'd struggle a bit. Would need a dolly and van with ramps.
Remove the knee board, board above the keys and the key cover. You'll be surprised how much lighter the piano is without them and they won't then fall off whilst you're moving it.
Handy hint when moving pianos - the treble (right side when looking from front) end is usually a lot lighter than the bass as the strings are thiner at the treble end. This is worth remembering if you are lifting the piano onto a trolley as you only need to lift the treble end and poke the trolley under the piano. It is also worth remembering when moving the piano down stairs - take the treble end down first as it is easier to hold up and hotch the bass end down one stair at a time.
