The Escalator Company shares N secrets about the escalator:
The first secret is this: the handrails and the steps move in the same direction, and their speed is actually different: the handrails are 2% faster than the steps.
Why are you faster? Why is it 2%? “A lot of people, especially the elderly, will grab the handrail when they take the escalator, so the speed can stretch the arm and keep the forward leaning position at a relatively fast speed, which can effectively prevent the fallback in some cases.” 2% The speed is calculated and it guarantees that you don’t have to adjust the armrest during a ride.
The second secret: What is the angle of inclination of the escalator? Announce the answer: no more than 35 °.
This, of course, has also been calculated. Only under this angle, the escalator will be relatively more stable, more powerful, more efficient and more stable. This is why most of the escalators have an inclination angle between 30° and 35°.
The third secret: the apron board and the step cannot be more than 4 mm on one side. This is also the national regulation: the distance between the one side is not more than 4 mm, and the spacing between the two sides is not more than 7 mm.
The reason is also for safety: “Seamless docking” may produce harsh metal rubbing sounds, and too much spacing may cause children to be curious and reach out. “Of course, no matter how scientific the design is, the children must go up the ladder under the leadership of the parents, and also prohibit the children from running and playing on the escalator. It is forbidden to push the stroller onto the escalator.”
