Footnote 1: The time it takes to lower the tower.

Information provided by Drake Dimitry, President of Heights Tower:

The time that the tower would take to fold over using a gearmotor we sell would be about 14 minutes. There are about 5 ft. or less of screw travelled to tilt the tower over. With 5 threads per inch, and the gearmotor having a rating of 22 rpm, which it stays fairly close to, the motor will have to turn 60" x 5 tpi = 300 turns, and that takes about 300 rev. / 22 rpm = 13 min. 40 sec to accomplish. While systems vary, most systems can be completely folded over in 60" or less.
