Escalaphodia is the fear of escalators.
Escalaphobia
I believe that this phobia is currently unnamed by the scientific community. It either falls under "acrophobia" or "fear of heights" or under claustrophobia or "fear of small, enclosed spaces." I would suggest something along the lines of sursumdeorsumphobia, which means literally, in latin, "fear of up and down" it seems to fit. Sursum is up and deorsum is down.
