Which term describes the devices that stop the lift at upper terminal positions?

• A. Upper Terminal Stopping Device
• B. Lower Terminal Stopping Device
• C. Footrest Obstruction Device
• D. Sprocket Alignment

Answer: (A)

The devices that stop the lift at the upper terminal positions are called the Upper Terminal Stopping Device. This component ensures the escalator or moving walk halts in the correct top position, coordinating with the control system to prevent overtravel and to align the car or steps with the upper landing for safe passenger exit.

In contrast, a device at the lower end would perform the same function at the bottom, but that’s a different term. A footrest obstruction device relates to detecting obstructions on the steps or footrests, not stopping at a terminal. Sprocket alignment deals with the drive train geometry and doesn’t control terminal stopping.
