Escalators have brushes at the bottom of the side walls for several reasons, primarily related to safety and maintenance. Here are the main purposes of these brushes:
Safety: The brushes on the bottom of the escalator's side walls serve as a safety feature to prevent objects from falling or being dragged into the gap between the moving steps and the stationary side wall. These brushes create a physical barrier that reduces the risk of personal belongings, loose clothing, or other objects getting trapped and causing accidents or damage.
Debris and dirt prevention: The brushes help to minimize the accumulation of debris, dust, and dirt in the gap between the steps and the side walls. They act as a barrier to prevent loose items, such as small stones, dirt particles, or litter, from falling into the gap and interfering with the smooth operation of the escalator. By keeping the gap clean, the brushes contribute to the escalator's efficient functioning and reduce the need for frequent maintenance.
Noise reduction: The brushes can help to dampen the noise produced by the contact between the steps and the side walls. As the steps move and rub against the stationary walls, the brushes absorb some of the vibrations and friction, reducing the overall noise level. This creates a more comfortable and quieter environment for escalator users.
Aesthetics: In addition to their functional purposes, the brushes at the bottom of the escalator's side walls can also serve an aesthetic role. They can enhance the appearance of the escalator, giving it a finished and polished look. The brushes are often designed to match the overall design and color scheme of the escalator, contributing to the visual appeal of the surrounding environment.
Overall, the brushes on the bottom of escalator side walls provide safety benefits by preventing objects from falling into the gap, help maintain a clean and efficient operation, reduce noise, and add to the overall aesthetic appeal of the escalator.
