What should be checked if an elevator's handrail is not at the correct measurement?

When assessing the issue of an elevator's handrail not being at the correct measurement, it is crucial to consider the return to return distance. This measurement determines the overall fit and functionality of the handrail as it relates to the elevator design and safety regulations.

If the handrail measurement is off, this may indicate that the return to return distance is not aligned with the standards, which ensures that users can safely and comfortably grasp the handrail while entering or exiting the elevator. An incorrect return to return distance could pose a safety hazard, as it affects the usability of the handrail. Therefore, checking this specific measurement will help ensure that the design adheres to safety norms and provides the necessary support for passengers.

In contrast, while cable tension, horizontal alignment, and step elevation may influence the overall operation and safety of the elevator, they do not directly address the vertical height and positioning of the handrail in relation to ergonomic and regulatory specifications.
