What Is an Escalator Safety Brush?
An escalator safety brush, also known as a skirt deflector, is installed along the sides of an escalator near the gap between the steps and the skirt panels. It helps discourage passengers from bringing shoes, clothing or other objects into contact with this gap, reducing the risk of entrapment.
The source material describes these brushes as a combination of a mounting base and flexible bristles. Their design is intended to meet the relevant requirements for escalator skirt deflectors and anti-climbing devices.
Types of Escalator Safety Brushes
Escalator safety brushes can be classified by their construction and bristle arrangement.
Aluminum Base with Plastic Bristles
This design combines an aluminum mounting base with a replaceable plastic-bristle strip. Compared with older metal-strip brushes, the flexible bristles are easier to fit around curved sections of an escalator.
The design also offers practical advantages in installation, corrosion resistance and routine maintenance.
Single-Row and Double-Row Brushes
The source material identifies two common configurations:
Single-row brush: Manufactured using either bristles inserted into a strip or bristles held by a metal strip.
Double-row brush: Manufactured using a metal strip to hold the two rows of bristles.
The appropriate design depends on the escalator configuration and the applicable installation requirements.
Key Features and Benefits
1. Easier Installation
Flexible bristles can follow curved sections more readily than rigid metal-strip designs. With an aluminum base, the brush strip can be fitted into the mounting profile more conveniently, helping simplify installation.
2. Corrosion Resistance
Traditional iron-strip brushes may rust and shed bristles when exposed to moisture. Plastic-bristle designs help address this issue and are more suitable for environments where corrosion is a concern.
3. Convenient Replacement
Escalator safety brushes are subject to wear through regular contact and friction. A replaceable brush strip allows maintenance personnel to replace the worn section without necessarily replacing the entire aluminum base.
4. Flexible and Wear-Resistant Bristles
The source material recommends flexible nylon bristles with good resilience and wear resistance. The bristles should recover after contact while remaining soft enough to reduce the risk of damaging clothing.
Flame-retardant nylon may also be specified where required by the relevant product specification.
Installation and Material Considerations
Correct installation is essential to the intended function of an escalator safety brush. The source material highlights several considerations:
Position the brush in accordance with the applicable dimensional requirements.
Follow the curvature of the skirt panel around bends.
Finish the ends smoothly and fit suitable end caps.
Ensure that the mounting base and brush are securely installed.
Check the brush angle, overall dimensions and clearance against the applicable requirements.
The source material gives a typical bristle projection of approximately 50–52 mm and lists brush-strip dimensions of 5 × 5 mm, 6 × 6 mm or 7 × 7 mm. These are reference dimensions from the supplied material, not universal specifications for every escalator.
The mounting base is typically made from aluminum alloy. The supplied material also describes an anodized surface treatment intended to improve surface durability.
Final dimensions, materials and installation positions should be verified against the escalator manufacturer’s instructions and applicable safety standards.
Why Escalator Safety Brushes Matter
The gap between an escalator step and its skirt panel is an important area to consider when assessing passenger safety. Properly selected and installed safety brushes help discourage contact with this gap and reduce potential entrapment risks.
For escalator operators and maintenance teams, regular inspection is also important. Worn, damaged or loose brush strips should be assessed and replaced when necessary, following the manufacturer’s maintenance guidance.
Conclusion
Escalator safety brushes are small components with an important role in escalator safety. Their effectiveness depends on suitable materials, a secure mounting structure, correct installation and timely replacement.
Understanding the available brush designs and their key features helps maintenance teams and equipment buyers make more informed decisions when selecting replacement components.
