An escalator handrail load monitoring and detection apparatus monitors and detects variations to a load applied to the handrail during operation. A distortable element is mounted to a handrail guide upon which the handrail rides and responds through distortions to downward-applied forces to the handrail. An electrical switch is activated by the distortion, allowing an output signal to be generated indicating that a particular minimum downward force has been applied to the handrail. The minimum force may be chosen to be above the range of forces normally applied to the handrail during normal passenger use, and thus be responsive to unsafe or improper operating conditions, such as when a passenger sits on the handrail or places packages thereon.
