Stops the lift before hitting an obstruction.

• A. Speed Governor
• B. Swivel Seat
• C. Carriage
• D. Final Terminal Stopping Device

Answer: (D)

Stops the lift before hitting an obstruction is handled by a safety mechanism placed at the ends of the run. The Final Terminal Stopping Device is designed to bring the escalator to a halt when the car approaches the terminal and an obstruction or misalignment could cause contact with people or objects on the landing. It acts as a protective stop at the terminal, ensuring the drive stops before any collision can occur.

This isn’t about controlling speed, which is the job of the speed governor, nor is it related to the moving carriage or the optional swivel seating. Those other components serve different functions, while the final terminal stopping device specifically provides a safe, immediate stop when obstruction risk at the terminal is detected.
