Is it reasonable to "stand on the right and keep on the left for emergency driving" when riding the escalator?

In some countries and regions, when riding an escalator, it is indeed required to "stand on the right and keep on the left for emergency driving", but the "walking left and standing right" method will cause the elevator to bear unbalanced pressure for a long time, causing the elevator to The right side is severely tilted, which affects the life of the elevator and increases the risk.

Guangzhou Metro announced on April 21 through its official WeChat account that according to a set of statistical data from a domestic subway: about 95% of the escalator step chains on the right side are obviously more worn than the left side, resulting in a slight tilt of the steps. The baffles and comb plates on both sides are increasingly worn.

When escalators are designed, although the maximum load capacity to withstand unbalanced pressure for a long time is taken into consideration, "running left and standing right" will indeed cause some parts of the escalator to bear excessive fatigue impacts and shorten the life of the equipment. , causing frequent escalator failures.

In addition, it is not scientific to leave one side of the escalator for passage, because it is not safe to walk on the escalator. The height of the escalator steps is different from that of ordinary stairs. The height of the steps of the escalator is 21 cm, which is higher than the 15 cm height required for stairs in public places. People walking on it may easily miss the step or be tripped. While walking, it is easy to bump into other passengers on the escalator, causing accidents. Passengers are advised not to walk on the escalator as much as possible, and no more than two people can stand on one escalator step. For passengers who are in a hurry, it is safer to use the stairs instead of walking on the escalator. After all, safety is more important than time.

In recent years, many cities at home and abroad have banned the practice of "walking left and standing right" when taking escalators. (Excerpted from: Monthly "Science" Rumor List April List)
