.... was out of order yesterday on my first attempt to use it after
finding out about it in this forum. Are sloping lifts less reliable than
vertical ones? I can't see why a vertical lift wasn't used in the
location in question, perhaps they were just showing off, but that isn;t
much use unless the thing works.

If the technology was reliable, it could perhaps be incorporated into
the central stairway of some elevator shafts.
