How should escalator steps be aligned properly?

Proper alignment of escalator steps is crucial for ensuring safety and functionality. The adjustment of the step chain tension plays a significant role in this process. When the tension is correctly set, it ensures that the steps move smoothly and maintain the correct alignment as they traverse the escalator's guiding rails. If the step chain is too loose, it can lead to misalignment resulting in gaps or uneven steps, which can be hazardous for users. Conversely, if the chain is too tight, it may cause excessive wear and tear or operational difficulties.

Although other options may relate to maintenance or operational aspects of escalators, such as ensuring the escalator is level for overall stability, they do not specifically address the core requirement for aligning the steps. Proper step chain tension guarantees that every step remains positioned correctly as it moves, thus maintaining safety and efficiency within the system.
