Which plate conveys the safe load rating and must be at least 6 mm tall?

• A. Capacity Plate
• B. Closing Speed
• C. Emergency Power Duration
• D. Obstruction Devices

Answer: (A)

The plate that communicates the safe load rating and must be at least 6 mm tall is the capacity plate. This sign is the official label on the escalator that lists the maximum safe load (and usually the number of passengers it can carry). The 6 mm height requirement is a readability standard, ensuring the rating is legible to inspectors and operators under various lighting and viewing angles. Other terms refer to performance or safety features (like how fast parts move or how long power lasts) and do not display the equipment’s load capacity, so they aren’t the plate that conveys the safe load rating.
