Step Type Escalator
This is the most common type of escalator which is quite resurgent these days. Now a days the steps which are being made are of metal whereas earlier these steps were made of wood, which could not be that successful. Step type escalators are popular as they can also go up or down, it can get flat, then up and down again. The steps of the escalator are mounted on the hinged circles, which tracks its appearance besides the steps which is kept visible from all the above steps. This escalator is designed to be quite safer as compared to any other type of escalator..
