Scary Story

I installed a 'spider' under a baby grand in a local hotel a few years =
ago, pretty much the way Wim described, except, that since it was such a =
small, and therefor not very heavy piano, I knelt under the piano and =
used my back to lift each corner in turn instead of using a jack . .  =
Started with the front legs, and, exactly as described below, without =
using the block, however, got the front or keyboard legs done.
Lastly, went to the back, tail, leg and lifted . . .  well I discovered =
an interesting phenomena about centre of gravity, momentum etc.
The two front legs, now being on the spider, where the castors are =
significantly inboard of the legs, gives the whole piano an entirely =
lighter feel at the back end . .  It went up entirely too easily, and =
would have kept going in a front somersault if I had not realized what =
had just happened, and grabbed that disappearing back leg with all my ( =
bank account inspired ) strength.
As I held on to the piano and fitted the leg into the little cup, I =
thanked my lucky stars that the piano and I had both survived . .=20
Moral of the story . . sometimes an assistant / spotter is a GOOD thing =
!!

Be careful Lance !

    I am ordering a piano truck/dolly system from Pianotek for a =

off.  I have car/piano stationary jacks to hold it up (only have 2) and =
I have a hydraulic jack.  I also have a portable engine hoist that I =

    Any experienced voices would be appreciated.  Thanks in advance. =20

  Assemble the truck as per instructions. Do not tighten the arm bolts, =
so you can move them in and put, and leave the plate bolts a little =
loose, so you can turn the arms. Position the truck under the piano, so =
that each arm is close to each leg. You want the arm that comes out of =
the plate at a 90 degree angle at the back. Use the jack to lift one =
leg, (preferably one of the front legs). You can remove the caster with =
a big screw driver. With the caster removed, position the arm under the =
leg, and put a piece of wood, like a small piece of 2x4, under the leg. =
Lower the jack and let the leg come down on the arm rest. The block of =
wood will prevent the other legs from coming up. Repeat this for the =
other two legs. You do not need to remove the lyre

  Good luck
