Something else that just occurred to me, who/what would control the levitate spell on each section? You couldn't leave it up to the passengers of the beanstalk (and cargo can't decide which way it wants to goif it's a pure non-living cargo lift), so would each section require an operator to control the sections magic? (basically to "use" the section like an item?)
What a job - report for work, punch in. Get transported to your section. Begin thinking "Up....Up....Up....Up.....Up.....Up...." for the next 8-12 hr shift.
I just had the thought pop into my head of the old elevator operators ("Going Up!"). This might make things a little complicated for manning the upward side, although the downward side wouldn't require any supervision if you went with the Feather Fall.
The levitate side is actually a good idea because you are not limited to upward travel, in case of an emergency you could reverse the direction to evacuate the orbital station in a hurry with 2x the downward cargo/passenger movement, or move anything else downward from orbit at a double rate.
Hmmm, that almost makes me want to lobby to see levitate used on both sides. That would give you the capacity to provide 2x the flow in either direction if needed. The only problem would be the financial end of it, the corporation would have to really have to lobby to get that past their financial departments....
The current version does use levitate on both beanstalks. The cost is the same, and that way only one type of ring section needs to be made.
If I made the down beanstalk use feather fall, you would reach the ground three times as fast (about 1.5 days insead of 4.4), because feather fall lowers at a rate of 60' a round as opposed to 20' per round for levitate.
I'm also assuming that since it's a continous magic item, it only needs a person to set the direction once it's activated. After that it automatically affects everything that comes within reach. Now that I think about it, these items probably qualify for the 30% discount because of their limitations, which would drop the price significantly.
I envision a a set of tracks leading into the bottom ring, with cars constantly moving cargo in. The cargo is clamped to the cars, and then released once they are centered in the ring. The cars are connected to the tracks, and won't be lifted. That way you can keep a pretty much constant flow of cargo. (Cars go in one side, release, go out the other side, and have more cargo loaded on as they follow the track around to the entrance again.)
