The "never stopping in the middle" can be a problem if one of your limit switches doesn't work properly. You might want to rethink your decision to let the lift keep running after the button is released.

How much other stuff is the operator going to need to do while the lift is in transit? Would it be too much trouble for him or her to be required to keep the button pressed in order for the lift to keep moving? That would make the lift a lot less likely to destroy itself if something failed.
