Escalating the Performance of Escalators
Mitsubishi has designed a variable speed
escalator that promises to ferry passengers from floor to floor at a rate 50% greater than that of current
escalators, while still maintaining normal entry and exit speeds. The trick is using large diameter pulleys at the
escalator's edges to force the rollers that support the steps to take wider turns, slowing them down. Look for
them in about two years in shopping malls near you.
