Yeah, I'd be concentrating on pulling down and moving all of the machines in one full day.
Once the pins are at the new location, you can set up the following day, or leave it for a few days if you're over the whole process. I know I would be after moving 40 machines!
This way, the truck can go back, as you won't need it again. Maybe even consider moving the parts separately by car either before or after, so you can focus on moving the machines.
That's how i'd approach it anyway, but I only have 8 pins.......
