What is the Flow Function on the Escalator?

Yes, this automatic ladder was created to transport humans, so we do not need to feel tired when having to explore the storied building.

However, do you know why the escalator has a vertical groove that covers every step?

Actually, this is one of the common things we usually take for granted, like why traffic lights are red, yellow, and green.

We must rarely observe this. However, the curve turns out to have a very important function.

If we look at the details, we will see a yellow part with a serrated shape on the edge of the stairs on the escalator.

This section is also often called a comb plate.

The curvature of the escalator serves to lock the step and the comb plate so that it prevents harmful materials from falling down the escalator's lips that can make the escalator break down or even break down.

In addition, the groove is made as a "reminder" for the leg when it is too close to the inner deck escalator.

Well, this way can help us avoid accidents or fall while climbing the escalator.
