What role do handrails play in escalators?

Handrails on escalators serve a crucial function in enhancing user safety and comfort. They are designed to give riders a stable and secure grip while ascending or descending, which helps to prevent accidents and falls. By providing support, handrails allow users to maintain their balance, particularly during the movement of the escalator, which can create an unsteady experience for some individuals. Additionally, having a handrail can make using the escalator more comfortable, especially for those who may feel apprehensive about the stairs moving beneath them.

While other features like the escalator's structural elements are responsible for keeping it in place, and aesthetics can play a role in design, the primary function of handrails is centered around user safety and comfort. Thus, this answer highlights the critical importance of handrails in the overall functionality and user experience of escalators.
