Hi RollingStone,
Sadly when moving jukeboxes sack barrows or pool table can be used for moving jukebox on the flat. however on stairs it is down to brute strengh, it can pay to remove the mechanism and amp to lighten the load when tackling any stairs, our worse case was lifting a jukebox up a spiral staircase almost one step at a time.
