Small Escalator

We often see two kinds of escalators in shopping malls, one is a very narrow step, can only accommodate a person standing, generally used in brand stores for customers to buy goods upstairs and downstairs, the width of this escalator is generally only 600mm. there is also a width of the escalator can accommodate 2-3 people standing at the same time, but the lifting height of the escalator is very low, usually only 1 m. We call these two types of escalators as small escalators.
