Since the opening of Nanjing subway, the passenger flow has been high. The reporter of Modern Express learned that in the first few years of the opening of the subway, when you take the subway escalator, you can always see passengers standing in the middle of the escalator, and those who are in a hurry can do nothing. In order to cultivate passengers' habit of civilized travel, Nanjing Metro has listed "walking left and standing right" on the escalator as a civilized norm.
After the implementation of the regulations, many passengers also said that the order of taking the escalator was much better. "Leave space on the left side of the elevator for people in a hurry to pass." Many passengers think that "walking left and standing right" is a sign of civilization.
In fact, at 20 1 1, the Nanjing Metro has cancelled the "left-standing and right-standing" regulation, and instead reminded passengers to "stand firm and hold on tight" and not to run on the escalator. This is because at that time, some people in the industry thought that the practice of "walking left and standing right" would lead to unbalanced escalator load and easy wear, which would lead to potential safety hazards. In addition, walking and running on the escalator, once you fall, it is easy to cause trampling during the peak passenger flow.
At present, Nanjing Metro does not advocate or object to the attitude of "going left and standing right", and the most important premise is to ensure the safety of passengers.
It is said that China, Hongkong, China, Taiwan Province Province, China, Japan and other places no longer advocate and publicize "walking left and standing right", and some have advocated "not walking, not running".
However, "going left and standing right" has long been the social norm.
Reason for agreement: Half-standing and half-walking can improve efficiency.
The reporter of Modern Express learned that "walking on the left and standing on the right" is the default rule of civilized manners in some developed countries and regions.
"This is an orderly way to ride." A netizen in Nanjing said that from the perspective of efficiency, half of the people walking on the fully loaded escalator can improve the carrying capacity of the elevator during peak hours.
"I have something urgent to catch the subway. I want to use the escalator to pass quickly and save some time." Xiao Liu, who works in a cultural company, said, "But the people in front are motionless, blocking the road so hard that they can't get through."
For the situation that "going left and standing right" has potential safety hazards, many citizens who are in favor of "going left and standing right" believe that there is no conflict between civilization and safety. "This kind of travel order can still be maintained, but we need to work hard on the escalator itself, such as improving the quality of parts."
Against: Safety first. Please take the stairs in time.
Some people think that there are many ways for passengers to get up and down stairs in subway stations, such as stairs, escalators and straight ladders.
"Generally, taking the escalator is to save effort, not to hurry." The citizen said that if you are in a hurry, climbing stairs is faster than taking the escalator. He said that the escalator steps are higher than the stairs and the design is not ergonomic. In fact, it is not safe to walk on the escalator.
Some netizens suggested that he check the information and consult relevant experts. "The design of the escalator is balanced. If it is only biased to one side, it will have an impact on the escalator and lead to safety hazards. "
Expert opinion: The most important thing to take the escalator is to "stand firm" and don't walk around.
Although many citizens think that "walking left and standing right" by escalator is both civilized and time-saving, in the opinion of elevator safety experts, "walking left and standing right" should not be advocated.
Jin Yan, director of the elevator department of Nanjing Institute of Special Equipment Safety Supervision and Inspection, said that from the safety point of view, the most important thing to take the escalator is to "stand firm". Jin Yan said that many foreign cities encourage passengers to stand on the right side of escalators on the basis of small passenger flow, but many cities in China have large passenger flow. If everyone stands on the right, the equipment will be more damaged. Moreover, passengers can only save a few seconds when walking on the escalator. If they walk quickly on the escalator during the rush hour, they will accidentally fall down, which will easily lead to the "domino effect" and many people will be injured. If two people stand side by side in each elevator, the traffic efficiency will be higher, the force will be balanced and it will be safer when there are many people.
It is understood that the national standard GB 16899, as the manufacturing specification of escalators, also stipulates: "Escalators cannot be used as stairs when they are not running." It can be understood that walking in the running state of the escalator is more unsafe.
Uneven stress for a long time, the escalator is easy to wear.
Passengers stand on one side of the elevator for a long time, and the elevator "can't eat". "Now escalators are designed according to balanced loads, that is, the forces on both sides of the steps are balanced." Jeff, deputy general manager of Nanjing Honghe Electromechanical Equipment Co., Ltd. explained that the escalator drives the step wheels to rotate along the guide rail through the chain, and each step is equipped with two step wheels. In order to increase flexibility and reduce friction, these treadles are generally made of rubber materials. "If passengers stand on one side for a long time, the pedals on one side are bound to be seriously worn and prone to failure."
In addition, a public report of Xizi Otis Elevator Co., Ltd. also pointed out that when "walking left and standing right" is implemented, the force on the right wheel is three times that of the left wheel. In the long run, these wheels will fatigue and wear until they are scrapped.
Moreover, the staircase of a general building is about 18 cm to 20 cm on each floor, while the escalator is generally 30 cm, which is obviously not suitable for walking. Building stairs will have a safety buffer platform every ten steps, and escalators not only have no such platform, but also have a design width that only allows two people to stand, which is not only inconvenient to walk, but also easy to bump into others.
Suggestion: When taking the elevator, pay more attention to the surrounding environment.
Walking elevators are different from stairs. They are not designed for walking. Walking or running on the escalator is not only unsafe, but also damages the elevator. Therefore, during rush hours, "walking left and standing right" should not be implemented, and in fact, it cannot be implemented. If you are in a hurry, you can go down the stairs. In Nanjing subway station and other places, there are stairs next to the escalator. During off-peak hours, "walk left and stand right" can be implemented. Take the escalator, stand on the handrail and pay attention to the surroundings. If you block people who are in a hurry, you can make way.
