Escalators or automatic pedestrian elevators, escalators, and escalators are a means of transportation that transports pedestrians in the form of conveyor belts. Generally speaking, escalators basically refer to escalators. Usually shopping malls are the most common, so what is the size of the escalator? ? What are the main parameters of the escalator?
What is the general size of the escalator?
Escalators are divided into two types: 30-degree angle and 35-degree angle. Now it is common to install an escalator with a step width of one meter. The outer diameter of the escalator is 1.55 meters. Meters can be installed) If a single unit is larger than 1.6 meters, the calculation formula for the span of the escalator is the front of the escalator plus the back of the escalator plus the middle size (to find the middle size of the escalator, use the trigonometric function tan30∠=0.577 and tan35∠=0.700. ) based on the escalator with a lifting height of 4 meters and an angle of 35 degrees to calculate the front end plus the rear end is about 4.8 meters (the size of each escalator manufacturer is different but the size difference is not big) plus (4.0/0.7=5.71)=11.4 meters. Thus, the width of two 4-meter escalators is 3.6 meters and the span is 11.4 meters.
The escalator is not based on the length, mainly depends on the height of the floor. Usually the height of the first floor of a medium-sized shopping mall is 5.4m, and the height above the second floor is 4.5m. Shopping malls are very expensive, so the smaller the projected area of the escalator, the better. At present, most of them use the specification of 35°-100.
Main parameters of escalator:
1. Lifting height: generally within 10 meters, in special cases it can reach tens of meters.
2. Tilt angle: generally 30°, 35°.
3. Step width: 600mm, 800mm, 1000mm.
4. Speed: generally 0.5 m/s, and some trapezoids can reach 0.65 m/s, 0.75 m/s
5. Theoretical conveying capacity: calculated according to the speed of 0.5 m/s, the conveying capacity of different step widths is 4500 persons/hour, 6750 persons/hour and 9000 persons/hour.
6. Safety height above the steps and pedals: above the steps of the escalator, there should be a vertical clear passing height of not less than 2.3m. The net height should be along the entire movement of the steps and pedals to ensure the safe and unimpeded passage of passengers on the escalator.
7. The safe distance between the outer edge of the handrail and the building or obstacle: the horizontal distance between the center line of the handrail and the adjacent building wall or obstacle shall not be less than 500mm under any circumstances, and the distance shall be maintained To a height of at least 2.1m above the steps of the escalator.
This height of 2.1m may be appropriately reduced if appropriate measures are taken to avoid the risk of injury.
The above is the knowledge introduction of the general size of the escalator and the main parameters of the escalator. I believe you will have more understanding after reading it. The content is for your reference only, and I hope it can be helpful to you.
