  Does anyone use a chain hoist?  Seems to me that there are several advantages:

    a.. Simpler setup than hoist-plus-block 
    b.. Cheaper initial investment 
    c.. Much better control... no fast, jerky pulls  
    d.. 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.
