What is the maximum angle of the inclination allowed on a moving walk?

  1. 5 degrees

  2. 10 degrees

  3. 12 degrees

  4. 15 degrees

The correct answer is: 12 degrees

The maximum angle of inclination allowed on a moving walk is set to ensure both safety and functionality. An angle of 12 degrees is considered optimal because it strikes a balance between providing a gentle slope for ease of use and maintaining movement efficiency. At this angle, users can safely and comfortably navigate the moving walk without excessive physical exertion or risk of falling. Steeper inclines may increase the difficulty of walking or standing on the moving surface, particularly for individuals with mobility challenges. Similarly, a lesser angle could compromise the efficiency of the system, reducing the intended purpose of facilitating horizontal movement in crowded areas. Therefore, 12 degrees is the standard established through safety evaluations and user experience studies, making it the correct answer.
