Answer:
Escalators are available with step widths of 600, 800 and 1000 mm. The most popular step width is 1000 mm. This step width gives the user unimpeded access to the step band, even with baggage and shopping bags. The other two step widths are used mainly for less frequented units or where space is restricted
