Requirements For Adjacent Areas Of Escalators And Moving Sidewalks

At the entrances and exits of escalators and moving sidewalks, there should be sufficient unobstructed areas to accommodate passengers. The width of the unobstructed area should be at least equal to the distance between the centerline of the handrail, and its longitudinal dimension should be at least 2.5m from the turning end of the handrail. If the width of the area increases to more than twice the center distance of the handrail, its longitudinal dimension is allowed to be reduced to 2m.

The vertical net height above the steps of an escalator or the treads or tape of a moving sidewalk should not be less than 2.3m. If obstacles in buildings can cause injury to personnel, corresponding preventive measures should be taken. Especially at the intersection with the floor slab and between the escalators or moving walkways installed at each intersection, a vertical anti-collision barrier with no sharp edges should be installed above the outer cover plate, and its height should not be less than 0.3m. (Except when the distance between the centerline of the handrail and any obstacle is not less than 0.5m)

The horizontal distance between the outer edge of the handrail and the wall or other obstacles shall not be less than 80mm in any case, and this distance shall be maintained at a height of at least 2.1m above the escalator steps and the steps or tape of the moving sidewalk. For escalators that are adjacent, parallel or intersecting, the distance between the outer edges of the handrail should be at least 120mm.
