INTRODUCING ESCALATORS
If the escalator is installed above the bottom floor, the pit should be cancelled; the construction of both downside and upside should be symmetrical. At the landings of the escalator, a sufficient unrestricted area shall be available to accommodate passengers. The width of the unrestricted area shall at least correspond to the distance between the handrail centre lines. The depth shall be at least 2.5m, measured from the end of the balustrade to any from obstacle. It is permissible to be at least 2.0m if the width of the unrestricted area is increased to at least double the distance between the handrail centrelines. The distance between the centrelines of the handrail and any obstacle is equal to or greater than 0.5m.
