 heaviest load a cherry picker can hoist? 
800lbs would be pushing it, I do believe.  Plus, if this IBM is tall it
won't be able to lift it high enough.
  Perhaps you can rent a car towing trailer?  Those are
very low to the
 ground generally and you may be able to push it onto the tracks.  Renting
 one may well be much cheaper than a truck with a lift gate. 
Do you mean a tow dolly?  Those don't have decks on them, just a spot
for each of 2 wheels.
