Wouldn't the inside rotor carry the cable that runs at higher speed and carries the gondolas and the outer loop be where the cars slow or stop for loading? I don't have experience with gondola construction but seems that the support cable would need it's own rotor and the loading section would be separate from it...
No, the cars do disconnect from the cable but they follow the same path as the cable. According to the author of Lift Blog the configuration we see in the aerials is very unusual.
