1. Size
In architectural design, the step height and width of escalators in shopping malls are generally 180x300.
2. Quantity The number of escalators must meet two selection criteria: ① meet the transportation capacity; ② passenger comfort. Regarding transportation capacity, the flow of people in the channel width per unit time should be considered, and the channel should be selected according to the maximum passenger flow under the most crowded level. Regarding passenger comfort, the area and shape of the building should be fully considered. Generally speaking, the service radius of all escalators does not exceed 50m.
For example: A commercial building is a high-end brand store, which adopts the store-in-store model. The long side length in the business area exceeds 100m, then the width of the main channel is 3200mm, according to the maximum speed of customers walking is 0.5m/s, and each person occupies an area of ​​800mm radius circle, that is, 2 people/㎡, then the number of people passing through the main channel per hour g=(0.5m/s)*(2 people/m2)*(3600s;h)*3.2m=11520 people. Since it is a two-way dual-channel, the number of people using the escalator up and down is 5760, that is, the actual transportation capacity of the escalator is greater than 5760 people. According to Table 1, the theoretical transportation capacity of the escalator with a step width of 1000mm and a speed of 0.5m/s can reach 9000 people/h, and the actual transportation capacity reaches 6300 people/h, which meets the transportation capacity. Since the long side length in the business area exceeds 100m, two sets of escalators should be selected according to the principle of passenger comfort.

3. Speed
Generally 0.5m/s, some escalator types can reach 0.65m/s and 0.75m/s.
4. Incline Angle
Article 3.1.8 of JGJ 48-88 "Standard Store Building Design Code" escalators installed in the business section shall comply with the following provisions: The horizontal angle of the inclined part of the escalator shall be equal to or less than 30°.
GB 50352-2005 "General Design of Civil Buildings" 6.8.2 Escalators and moving walkways should comply with the following regulations: ① The inclination angle of the escalator should not exceed 30°. When the lifting height does not exceed 6m and the rated speed does not exceed 0.50m/s, the inclination angle is allowed to increase to 35°
②) Commercial buildings are often designed at 30° for comfort and space saving considerations.
