Support structures connecting chair lift to steps?

• A. Brackets
• B. Protractor
• C. Stairway Angle
• D. Track

Answer: (A)

Brackets are the attachment points that hold and align the chair lift with the steps. They provide the rigid, load‑bearing connection needed to transfer the weight and motion from the chair mechanism into the step assembly, keeping everything in proper position as the escalator or moving walk operates. A protractor is just a measuring tool for angles, not a structural connector. The stairway angle describes how steep the incline is, not a component that links parts together. The track guides the steps’ movement but doesn’t serve as the mounting connection for the chair to the steps. So the brackets are the correct choice because they specifically function as the support structures connecting the chair lift to the steps.
