Guangzhou Metro was released on April 2 1 day through official WeChat. According to a set of statistics of a subway in China, about 95% of the right escalator step chain is obviously more worn than the left escalator step chain, which leads to a slight inclination of the steps and increased wear of baffles and comb plates on both sides of the steps.
In the design of escalator, although the maximum bearing capacity under long-term unbalanced pressure is considered, "walking left and standing right" will indeed lead to excessive fatigue impact on local parts of escalator, shorten the service life of equipment and make escalator frequently break down.
In addition, it is unscientific to leave one side of the escalator for traffic, because it is unsafe to walk on the escalator. The stair height of escalator is different from that of ordinary stairs. The height of escalator stairs is 2 1cm, which is higher than the height of 15cm required for stairs in public places. When people walk on it, it is easy to step on the air or trip, and it is also easy to bump into other passengers on the escalator during walking, causing accidents. Passengers are advised not to walk on the escalator as much as possible, and there are no more than two people standing on the first step of the escalator. Passengers who are in a hurry, it is safer to take the stairs instead of the escalator. After all, safety is more important than time.
In recent years, many cities at home and abroad have stopped "walking left and standing right" when taking escalators. (Excerpted from the April list of the gossip list of Science)
