Article 15- Escalator & Moving Walk Balustrade Safety Devices
Escalator & Moving Walk Anti-Climbing Device
To ensure prevention of stepping on the Lower Outer Decking and climbing from outside of the balustrade we must install anti-climbing device. This device is located on the lower outer decking and starts at a height of 1000 ± 50 millimeter from the lower finished floor surface. The length of the device is 1000 millimeters which is parallel with the balustrade. To provide passenger hand and fingers safety the height of this device can be extended a maximum of 25 up to 150 millimeters below the handrail and the distance between the handrail and ant-climbing device must be more than 80 millimeters.
Escalator & Moving Walk Access Restriction Device
When the escalator/moving walk is installed beside the wall and the Lower Outer Decking width is more than 125 millimeters for prevention of standing on the lower outer decking we must install an access restriction device at the top and bottoms on the walls.
The distance between the balustrade panel and access restriction device must be less than 120 millimeters.
When we have two escalators/moving walks in parallel arrangement and the combined lower outer decking width of both escalators are more than 125 millimeters we must install access restriction device at the top and bottom in the beginning of the lower outer deckings.
To provide passenger hand and fingers safety the height of this device in both arrangements can be extended 25 up to 150 millimeters below the handrail
Escalator & Moving Walk Anti-Sliding Device
When the escalator/moving walk has a solid balustrade type which includes Upper Outer Decking and the escalator is installed beside the wall and the distance between the walls and the center of the handrail is more than 300 millimeters for prevention of sliding on the upper outer decking we must install an anti-sliding device. The distance between the handrail and anti-sliding device must be more than 100 millimeters and spaced no greater than 1800 millimeters apart. The height of the device must not be less than 20 millimeters and must not have any sharp corners or edges.
When we have two escalators/moving walks in parallel arrangement and the distance between the centers of their handrails is more than 400 millimeters we must install an anti-sliding device
Note: All exposed fastener heads for the balustrade safety devices must be of the vandal resistant type.
