What is the correct method to measure an escalator handrail?

To measure an escalator handrail accurately, the appropriate method is to assess the distance between the return points of the handrail. This measurement, referred to as "return to return," ensures that the entire functional length of the handrail is accounted for, including any curves or changes in direction.

Measuring from return to return is essential because it captures the complete path that the handrail takes throughout the escalator. This is important for safety and design purposes, ensuring that the handrail provides proper support and is consistent in length across the escalator's travel.

Other potential methods, such as measuring the length of the rail, height from step to rail, or the distance between balustrades, do not provide a complete and accurate representation of the handrail's functional length as they fail to account for the handrail's geometry and its return to its original position. This highlights the necessity of employing the correct measuring method to ensure both safety and compliance with design standards.
