What aspect of escalator installation concerns weight-bearing capacity?

Load testing is a critical aspect of escalator installation that ensures the system can safely support the intended weight and usage conditions. This process involves placing weights on the escalator and running it to simulate normal operation, which helps verify that all components, including the steps, handrails, and drive mechanisms, can withstand the stresses they will encounter in real-world use.

Conducting load tests is essential not only for safety but also for compliance with industry standards and regulations. It verifies that the escalator meets the required specifications for weight capacity, ensuring that it can reliably handle the anticipated number of riders, including their combined weight.

Safety barriers, emergency protocols, and material quality assessments are also important in the overall safety and functionality of an escalator, but they do not directly address the specific concern of weight-bearing capacity as load testing does.
