The average set designer/td on that level probably isn't qualified to be designing mechanized scenery. Witness the incident you described. From what describe, this sounds like an on/off up/down lift with no acceleration or deceleration in the motion.  I'd say "motion profile" but it doesn't sound like there was much of a profile involved. 

But to answer your question there should indeed be two limit switches per direction on this machine.
