Article 33 -Escalator Landings dimensions and safety requirements

Escalator landings requirements

In this article we intend to explain escalator landings requirements and dimensions which must be taken into consideration and are as below:

Escalator and moving walk landing areas including comb plates and floor plates must have a surface to provide a secure foothold for passengers with a minimum length of 850 mm which starts from behind the comb teeth.

In order to provide a secure foothold for the passenger when stepping onto the escalator, a horizontal moving landing area composed of a number of steps must be considered which starts at the intersecting line of the comb. Due to the fact that each step has a depth of 400 mm the below conditions must apply:

The horizontal steps must be a minimum of 2 when the nominal speed is up to 0.5 m/s to provide an 800 mm moving landing area.

The horizontal steps must be a minimum of 3 when the nominal speed is between 0.5 to 0.65 m/s or the vertical height is more than 6 m to provide a 1200 mm moving landing area.

The horizontal steps must be a minimum of 4 when the nominal speed is more than 0.65 m/s to provide a 1600 mm moving landing area.

Note: In the moving landing area, a 4 mm vertical difference between the last step and the previous one is authorized.

At the upper landings of moving walks, with more than 6 degrees angle of inclination,   a minimum 400 mm horizontal moving landing area must be considered by a number of pallets which starts from the intersecting line of the comb.
