This set of photos is a rough approximation of how my Pump It Up GX machine was prepared for shipping by the seller. I'm not an expert in packing; the information here is my best guess at how to do this.
The pad connector box can be removed from the front of the cabinet with a phillips screwdriver.
Four wires to disconnect. They may be stubborn, but wiggle them back and forth and they'll come apart eventually.
Same thing on the pad itself.
The pad connector can be shipped on top of the pad, ideally wrapped in some sort of packing material and tied or taped down.
Open the top cover in the back of the machine. It should be held on by two phillips screws.
The marquee is connected with three cables, which need to be unplugged.
The marquee connectors come down through a circular hole at the top of the machine. After disconnecting them, push the three dangling cables up through the hole as far as you can.
The marquee may be connected to the top of the machine with three screws. Unscrew these to allow it to be moved.
Be sure it doesn't fall forward when you do this! It will sit on a small metal bracket that should hold it in place without the screws, but it's front-heavy and somewhat unstable when unscrewed.
From the front of the machine, pull the marquee toward you to unseat it from its bracket, and lift off carefully. Be ready to catch it when it wants to fall forward; it's surprisingly heavy!
The marquee can be laid on its back on the pad. Ideally, this would be entirely wrapped in bubble wrap and tied or taped to the pad.
Small bits (screws from the pad connectors and marquee, power cable, etc.) can be conveniently stashed in the coin bucket.
The keys to open the service and coin doors can be taped to the front of the display in a ziploc bag or something similar.
If it's necessary to separate the pads (it might not be), the metal brackets holding them on in the front and back can be unscrewed with a 6mm Allen wrench.
Same thing at the back of the pad.
With the brackets removed, gently pull the pads apart a few inches in the front. Two cables connect them together.
These should have a little bit of slack that can be pulled out to disconnect them. Like the connectors in the tube running to the machine, these may be stubborn.
Here are some photos of the way my machine was packaged when it was delivered to me. I don't have all of the specifics, but the basic idea seemed to be to use a layer of cardboard to protect the cabinet and pads, then wrap that in plastic, then tie that down to the pallets with metal strips.
Bill of lading. Freight class 125.0. 600 pounds for cabinet (71 x 50 x 52), 500 pounds for pad (48 x 40 x 77).
Marquee bubble wrapped on top of pads.
Pads were on an extra-wide pallet, with a normal sized pallet underneath. If necessary, I suppose each one could have had its own pallet. It might also be possible to stack them?
Lots of black plastic wrapping up the cabinet.
The cabinet's pallet was set up in such a way that allowed it to be rolled off onto a surface at the appropriate height. This was particularly convenient for unloading.
