Yes, Paul, I have two 1/2 ton load hoists mounted on cars on an I-beam
across the ceiling so that I can roll the plate away from the piano to set it
down. If you'd like a picture, I could endeavor to make one. ;-)

Does anyone use a chain hoist? Seems to me that there are several
advantages:
* Simpler setup than hoist-plus-block
* Cheaper initial investment
* Much better control... no fast, jerky pulls
* A little bit of exercise
IANAR (I am not a rebuilder) but I know one who does use a chain hoist and
I've observed very smooth, controlled, fluid plate lifts/drops with it...
and really not a lot of muscle needed.
Here's a link to one example... I do not own one.

I DO own a lever/cable hoist, which I HAVE used to pull a plate. DO NOT
EVEN consider using a lever hoist. Just trust me. It's dangerous and
extremely awkward. No, I do not speak from a negative experience (except the
awkward part.)

Thomas: what's the capacity on your hoist? Harbor Freight sells (according
to website) a 1300# and 880#. Although Ron says a 1 ton will handle
anything, is that necessary? If i need up to a ton, then i'll need 2 hoists. The
harbor freight hoists lift at 33'/min. which translates if i did my calcs
correctly to 6.6"/sec. - much faster than the 2"/sec. you've achieved Tom. I
dont plan on doing a concert grand, right now i've got a 58" upright,
which is huge.

Great! Seems like the hoist that attaches to the beams would
be the most space saving. My beams are 2" x 7 1/2" and spaced
14 1/2" apart. That looks pretty strong to me (knowing nothing
about it). How much might a plate weigh - what capacity should
I go for? Would 1300# do it?
A 4x4 (or 4" pipe) laying on top and spanning four or more joists,
with the chain hoist hung in the middle, is the easiest semi
permanent installation. A one ton chain hoist will lift anything
you'll need, but I use two hoists for big plates. I like the
control and stability better.
