Jul 13,2025

The escalator comb plate, a crucial safety component at the escalator/moving - walk ends, prevents entrapment of items or body parts. During maintenance:
 
 
1, Power Off: Always cut off the escalator power supply first to avoid unexpected start - ups.
2. Inspection: Check for cracks, wear, or deformation. Replace damaged comb plates promptly.
3, Cleanliness: Keep the comb plate and its surrounding area clean. Remove debris that might affect its function.
4, Alignment: Ensure proper alignment with steps. Misalignment can cause malfunctions or safety hazards.
By following these, we safeguard passenger safety and ensure the escalator runs smoothly. https://www.deysse.com/product/Escalator-Spare-Part-Aluminum-Comb-Plate-Left-3389.html

When purchasing replacement escalator comb plates, the following information is generally required:

1. Escalator Model and Specifications

  • Brand and Model of the Escalator
    Provide the exact brands and model number of the escalator. Different models may have customized comb plate designs in terms of size, tooth shape, and installation dimensions. 
  • Technical Parameters
    Include parameters like the step pitch (the distance between adjacent steps, usually a standard value such as 100mm or 120mm, but specific to the escalator), and the width of the escalator (e.g., 800mm, 1000mm wide escalators use different comb plate sizes).

2. Comb Plate Details

  • Existing Comb Plate Dimensions
    Measure and supply the length, width, and thickness of the current comb plate. Also, note the number of teeth and the shape of the teeth (e.g., straight - edged teeth or with specific curvatures). For instance, “Comb plate length: 300mm, width: 150mm, thickness: 10mm, 22 teeth with curved edges ”.
  • Material Requirements
    Specify if there are special material needs, such as high - strength plastic (common for yellow comb plates visible in the picture) with flame - retardant properties, or aluminum alloy (for metal - colored ones) with anti - corrosion treatment. Like “Require comb plates made of flame - retardant ABS plastic for the yellow parts; aluminum alloy with anodized coating for the silver parts ”.

3. Installation and Compatibility Information

  • Mounting Hole Positions and Sizes
    Record the position (distance from the edges) an
  • d diameter of the mounting holes on the comb plate. This ensures the new comb plate can be properly fastened to the escalator structure. E.g., “Two mounting holes, 50mm from the left and right edges respectively, hole diameter 8mm ”.
  • Compatibility with Other Components
    Mention if the comb plate needs to be compatible with specific step types (e.g., full - aluminum steps, composite material steps) or skirt board designs (the side panels of the escalator) to avoid mismatches that could cause safety risks. 

4. Certification and Standards

  • Compliance Documents
    Request that the supplier provides certificates showing compliance with relevant safety standards.
  • Quality Assurance
    Ask for details on the quality inspection process, warranty period (e.g., “1 - year warranty against manufacturing defects ”), and after - sales support in case of installation or performance issues.
