Includes cable slapping and component misalignment?

• A. Noise Sources
• B. Curved Installation
• C. Battery Maintenance
• D. Platform Components

Answer: (A)

Noise sources are issues that produce audible or structure-borne noise in an escalator system. Cable slapping happens when drive cables or belts strike surfaces due to slack, tension problems, or misrouting, which creates a recognizable tapping or slapping sound. Component misalignment causes rubbing and uneven contact between parts, leading to metallic or grinding noises. Seeing these signs together points to problems that generate noise, and the technician’s first step is to locate and fix the source of that noise—check and adjust tension, realign pulleys and guides, secure components, and inspect for wear. The other topics aren’t about the same diagnostic category: curved installation concerns geometry and alignment in a way that isn’t specifically about noise sources; battery maintenance isn’t typically part of escalator drive-noise diagnostics; and platform components refer to structural parts rather than issues that produce noise.
