Routine checks to ensure lift functionality and safety.

• A. Periodic Testing
• B. Maintenance
• C. Electrical Installation
• D. Folding Seat

Answer: (A)

Periodic Testing is about scheduled checks that verify the escalator or moving walk will operate correctly and safely. It goes beyond everyday maintenance by applying defined procedures and safety checks at set intervals, such as confirming smooth step and handrail operation, proper braking and speed, door and safety device function, and overall control system performance. These tests are carried out by qualified personnel and follow manufacturer guidelines and safety codes to catch potential issues before they become faults.

Maintenance covers the ongoing care and repairs needed to keep equipment in good condition, which can include lubrication, part replacements, and adjustments—broader than routine verification of operation. Electrical Installation refers to setting up wiring and electrical components, not ongoing checks of current performance. Folding Seat is not related to the lift’s safety and function.
