Barry said:"What's the best way to move an entire booth"?
Easy. RYDER. With a Tommy Lift instead of a ramp. You'll never go back. Trust me.
Now that we have the mode of transportation taken care of, lets go to the next part.
Projector heads should be transported in a way that they will not leak oil all over the place, if they are Centurys, and you separate the soundheads from the picture heads, be sure to remove the oulley from the mainshaft on the picture head to prevent it from having the weight of the picture head sit against the mainshaft, possibly cracking the casing at the bearing there.
Platters: remove the brains, keeping all the parts together for each individual brain in a labeled ziploc bag or small box, so that the parts go together exactly as it came apart, same for any other hardware for any other equipment. Remove the discs, and the V-or U-shaped base if you have to to get it out the door then reassemble the base before loading it on the truck. Be careful not to damage any of the rollers on the platter tree during the move.
Lamphouses: Remove the xenon bulb and replace it into its orignal packaging if possible. If there is no original packaging ( the plastic wrap or plastic casing) then carefully wrap the bulb(s) in CLEAN cloths or towels and place them into a cardboard box and label them as 'unboxed xenon bulbs-fragile-explosive'...
Miscellaneous Wiring: Try to keep as much of the lamphouse-to-power supply and projector-to-console/pedestal wiring intact either by disconnecting it at one end or if you must cut, cut so that the wiring can be reconnected again with minimum hassle, if the same equipment will go into service at another location.
Sound Systems: If at all possible, try to keep all sound racks intact and complete, only disconnecting power speaker and input from them, that way they could be used again with little rewiring, and it makes for less room taken up by boxed up sound equipment. Speakers should be transported cones facing each other or against a solid object like the side or front wann of the truck, to prevent damage by any shifting objects in the truck. (Of course if any of this sound equipment has tubes in it, please email me and i will make you an offer! )
Horns can be transported loose, just be careful not to knock the drivers against anything.
Basically, any other booth equipment (make up tables, rewind benches, projector pedestals, dimmers, etc can be loaded and transported like any other equipment.
