Which term represents riser height multiplied by the number of steps, divided by minutes?

• A. Incline Speed
• B. Overspeed Governor
• C. Riser Calculation
• D. Vertical Speed

Answer: (C)

Riser height times the number of steps gives the total vertical rise of the escalator, and dividing that by the minutes yields how fast that rise occurs per minute. In NEIEP terminology, that specific calculation—the rate at which the risers add up to vertical travel over time—is called a riser calculation. It’s the labeled process used to determine the vertical travel rate from the riser height, step count, and time. This differs from incline speed, which is the motion along the inclined path itself, and from the overspeed governor, which is a safety device, while vertical speed is the actual rate of vertical movement resulting from the calculation.
