In the usual basement shop, with a ceiling full of exposed
floor joists, it is easy to install lift points between the
joists, using 2x4 framing hangers, and short sections of iron
pipe. Then you use a come-a-long to give the heavy instrument
some altitude. Don't stand underneath it!
That is how I put my machines on their bench stands, and how
I got my fluke HV AC calibration amplifier, all 140lbs, in its
rack.
Consumer grade block and tackle sets have too much friction to
be of much use. To effectively use a block and tackle, it needs
to have ball bearings in its pulley sheaves.

Yeah; ;-) except dollies can't lift from the top. My hand truck gets a lot of use...
Hmmm, swing out arm with a block and tackle?

A buddy of mine has one, and it works really well- I think he's gotten away with lifting 700lbs with it.
I have an air powered hoist rated at 300, which is all I'd put my garage roof through without extra support (I've done 900lbs with a chain hoist and supports). What I really need is a hoist that folds up, doesn't have long extensions, fits through a narrow door way, has large wheels so it works over grass/dirt/transitions, can lift via a table or sling, and can handle anything form a scope to a pallet of scopes... we can dream...
Part of this sounds like a refrigerator dolly....
