Which removes power from the unit at end of travel?

• A. Final Limit Switch
• B. Swivel Seat Check
• C. Chassis Tongue
• D. DirectionSwitches

Answer: (A)

At the end of travel, power is removed by the final limit switch. This device is wired into the drive circuit and is actuated when the escalator reaches its stop position. When activated, it opens the electrical circuit to the traction motor, causing the unit to stop and preventing further movement. This switch is part of the control system that enforces travel limits and provides a safe shutdown to prevent overtravel. Other items listed don’t perform this function: a swivel seat check is not involved in end-of-travel power control, a chassis tongue is a structural component, and direction switches control movement direction but don’t automatically cut power at the travel limit.
