What does the term "balustrade" refer to in escalators?

The term "balustrade" specifically refers to the protective barrier that supports handrails on escalators. It is an essential safety feature, designed to prevent users from accidentally falling off the escalator and provides a stable grasp for individuals as they ascend or descend. This structure not only enhances safety but also contributes to the overall design and functionality of the escalator.

Understanding the role of the balustrade is crucial for anyone involved in escalator installation and maintenance, as it ensures that safety standards are met while providing a secure environment for users.
