Which term refers to the activation mechanism that responds to the incline angle to limit speed?

• A. Tripping Point
• B. Vertical Speed
• C. Riser Calculation
• D. Incline Speed

Answer: (A)

The activation mechanism is the tripping point. It’s a preset incline angle at which the drive control automatically engages a speed-limiting or braking action to keep the escalator from moving too fast on steeper slopes. As the incline increases and reaches this point, the mechanism triggers and reduces speed to maintain safe operation for riders. This is different from vertical speed (the rate of ascent), riser calculation (step count to reach a floor), or incline speed (a descriptive speed parameter) because those don’t describe the actual trigger that enforces the speed limit based on the incline angle.
