Which device stops the lift at the upper landing under load?

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

Answer: (A)

The key idea here is that at the top end of an escalator, a stopping device is built to halt the car precisely at the upper landing, and it must work reliably even when the escalator is loaded with passengers. The device that does this is the upper terminal stopping device. It senses that the car has reached the upper landing and starts the stop sequence, coordinating with the drive and brake system so the car stops smoothly and aligns with the floor surface for safe disembarkation. This is exactly what’s needed to prevent overtravel past the upper deck when the load is present.

The other options don’t perform this function. A footrest obstruction device would relate to detecting obstructions under the steps, not stopping at the top. Sprocket alignment concerns the drive-train geometry, not the stopping action. Routine inspections are maintenance activities, not a device that actively stops the lift.
