    I've not yet lifted out a grand plate or I'd probably already know the answer to this. But would something like this be useful for pulling plates?

    This DIY Crane Can Move Your Heaviest Tools
    Gantry cranes are those large structures you see in shipyards that are used to unload shipping containers. But when they're sized down to more manageable proportions, the same mechanical principle can be applied to moving heavy objects in a workshop or even your home.

    You betcha. A lot of shops have something just like this. The down side
    is it takes a lot of room to move around and store. You also need a high
    enough ceiling to use it. I didn't have the room, so I installed two
    small I beams on my ceiling, with trollies and chain hoists. I can use
    both to better control big plates, or either (depending on where there's
    room at the time) for smaller ones. No storage problem. I just roll the
    hoists to the end of the track, and loop the chains up out of the way.
    Craigslist is a wonderful thing...

    Similar to Ron's setup, I have a half ton hoist on a track. My shop is in my cellar and it is attacked to the main central beam. There are two pullies so there are three cables lifting. The eyescrew in the beam supports one of the cables via a hook end.

    John -
    Ron and Jon's setups are far more elegant and efficient to be sure, but another option is to visit your nearest Harbor Freight store and purchase an engine hoist for $200.  No installation of any kind, ya just go down and purchase it and you're done.  "Folded", it has a very small footprint - maybe 2' x 2'.  I have pulled well over 20 plates with mine, with little fanfare.  Here's a link to a current offering at Harbor Freight:

    But for about the same money, you do not have it taking up any floor space. Around here, that's at a premium.

    Hey, no argument here, it's just another option.  Sure, the cost for materials is roughly similar, but ya gotta admit there are distinct labor costs involved in installing the tracking, and perhaps/likely beefing up the beam you are attaching to, depending on your space.  Is the labor involved somehow not accountable for part of the cost?

    Hey, I think your system is great!  For me, I managed to find a 2x2 space to store the engine hoist, so it was the path of least resistance for me.  Works great, for what I perceive as less overall total cost.  Everyone's mileage may/will vary, and everyone's needs are different.

    I agree on that one. John Formsma has seen what I generously call my
    shop. Some places have bigger freezers. The problem with putting in an
    overhead gantry is, besides ceiling height, cost. I bought a 1 ton Yale
    hoist for $25, and a 2 ton Jet for $30 from garage sales about five
    years apart. The 2 ton is overkill and geared way too low, but the price
    was right. I bought two 10'-12' lengths of I beam and three trollies for
    $40 total from a Craigslist listing about ten years ago and put the
    whole mess together into what has been a system I wish I'd have had all
    along. It would have cost me well over ten times that much new. A lot of
    people are using engine hoists like Mark suggested and are quite happy
    with them. I never have, so I can't say one way or the other about them.
    I am sure impressed with being able to hoist a plate and trolly it over
    to the other side of the shop though, without moving the piano.

    You can also throw a 10' dead man across the ceiling joists and hang a
    chain hoist from a loop of chain around that. With that setup, you move
    the piano out from under, which is easier without a plate adding weight.
    So that's the cheapest and quickest way to go. I did that for a while
    after I bought my first hoist.

    Lots of options. I do recommend shopping around for a chain hoist
    though, while you're deciding between that and the hydraulic engine
    hoist. Even for the same price, I'd way rather have a 75 year old
    Wright, Yale, Jet, Budgit, Peerless, or lots of other possibilities,
    over a new Chinese made hoist of 1/5 the weight and the same (overly
    optimistic) load rating. The new lightly built cheap stuff scares me.
    One ton is adequate even for a Baldwin SD-10 or Julius Bauer, and you
    won't have to pull a mile of chain to lift your plate a foot like you
    will with a 2 ton. That's the geared hoists with a loop chain and a
    bigger lift chain. Some techs are using the old differential hoists to
    good effect. They work great, and are as simple as hoists get, but there
    is more chain to keep track of as you use them. Takes a bit more muscle
    too. One ton rating here too.

    I also have an old Yale 1 ton differential, so you're welcome to drop by
    and lift my saw or something with each of the three hoists to see what
    you think.

    So whatever you decide, do some prospecting first and play what if to
    try to narrow down what you'll live with most comfortably. And let us
    know how it's going.

    Another advantage to a hoist is being able to use it to set up a piano by yourself. I set up and took down an SD10 with it, also an Ampico player. Also for flipping the plate to bang out the hitch pins for vertical hitch pin installation. The cable ran to a pulley to drop down to the plate. You need more space to use a lift because of the area the lift itself takes up. 

    My first hoist was not on a track but fixed to the beam. You can see salvaged opposing upright plate bolts reinforcing the beam on both sides. The eyescrew that once supported this first hoist's pulley is now installed on the other side of the beam to support the third cable. This hoist was initially used in a second floor shop to hoist pianos up thru a cut out in the flooring. This shop location is much better.

    Last year I finally put a hoist in my shop. I didn't have much room, so
    here was my solution.
    I researched how much load wood can support and became comfortable using
    a 2x6 x13. As a safety factor, I used two 2x6s bolted together for the
    header. For still more safety, I added two trusses to support the
    header. Two 2x4s mounded to the walls support the header at both ends.
    Since everything is screw or bolted together, I could take it down in
    about 10 minutes.
    It is high enough to remove a plate while still being able to open my
    garage door. As long as I miss the trusses I won't bump my head. After I
    finishing the hoist, I'll leave the frame in place and remove the
    come-alongs because I do bump my head on those.
