I moved mine by myself, removed the pump and motor then used a hand truck to get the tank moved, then the pump & motor were reinstalled, here is a photo when it was disconnected & moved out of the way for painting.
That back part of the shop was later demoed & replaced.
The existing roof was still in place as dirt floor was replaced with concrete, & proper footings.
After most of the existing structure was demoed.
Before the place got cluttered, but before the pump wiring got cleaned up, the wiring irked me for years.
Now back to the original topic, be careful, compressors are heavy & expensive, and injuries are also expensive to treat.
