Escalators are a common feature in shopping centers, transit hubs, and other public spaces.

One often overlooked component of the escalator is the row of brushes located on the sides near the steps.

But what exactly are these brushes for?

Let's delve into their purpose and functionality.

Preventing Accidents and Injuries

The brushes on the sides of escalators are not merely decorative; they serve a vital safety function.

Their primary role is to keep items such as shoelaces, loose clothing, or other objects away from the gap between the steps and the side of the escalator.

This is crucial in preventing entrapment and the associated injuries that could occur.

Without the brushes, there would be a higher risk of these items being caught in the gap, potentially leading to accidents.

Mitigating Dust and Debris

In addition to their role in safety, the brushes also help in limiting the amount of dust and debris that enters the escalator mechanism.

While they may not entirely prevent the entry of particles, they certainly reduce the accumulation of dirt, thus contributing to the overall maintenance and longevity of the escalator's moving components.

Controlling Static Electricity

Furthermore, another lesser-known yet equally significant function of these brushes is their ability to ground static charges that may build up during the escalator's operation.

By dissipating these charges, the brushes help in minimizing the risk of static discharges, which not only pose a safety hazard but could also potentially interfere with the escalator's electrical systems.

In conclusion, while often unnoticed, the brushes on the sides of escalators play a crucial role in ensuring safety, mitigating maintenance issues, and controlling static electricity buildup.

The next time you step onto an escalator, take a moment to appreciate the often-overlooked functionality of these unassuming brushes.
