Article 15- Escalator Balustrade Safety Devices

Safety device to prevent passengers falling from the balustrade

In this article, we intend to introduce the balustrade safety devices which are useful to reduce the danger of passengers falling.

For this purpose there are three devices which are useful for passenger safety as below:

Escalator Anti-climbing device 

To ensure prevention of stepping on the lower outer decking and climbing from outside of the balustrade we must install an anti-climbing device(s). This device is located on the lower outer decking and begins at a height of 1000 ± 50 millimeters from the lower finished floor surface. The length of the device is 1000 millimeters which is in parallel with the balustrade. To provide passenger hand and fingers safety the height of this device can be extended a maximum of 25 and it can go up to 150 millimeters below the handrail and the distance between the handrail and anti-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 an access restriction device must be installed at the top and bottoms on the walls. The distance between the balustrade panel and the access restriction device must be less than 120 millimeters.

When we have two escalators/moving walks in a parallel arrangement and the combined lower outer decking width of both escalators are more than 125 millimeters, an access restriction device must be installed at the top and bottom at 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 

In escalators/moving walks with solid balustrade 

which has upper outer decking when the escalator is installed beside the wall and the distance between the wall and the center of the handrail is more than 300 millimeters,  for prevention of sliding on the upper outer decking anti-sliding device must be installed. 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.

Also, when we have two escalators/moving walks in a 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.
