I was thinking of putting the bladder or whatever under one end at a time...
What I'd REALLY do is use my $5 harbor fright furniture mover... little bar and plate on wheels that you stick under one end and step on.. lifts about 3 inches so you can put the cute lil wheels under things... I've moved my lathe with it a few times... and I can't even slide that sucker on the floor by myself.. *g*
