What is the purpose of swing doors in elevator systems?

Swing doors in elevator systems are designed primarily to provide access in spaces where sliding doors may not be practical. This is particularly relevant in areas with limited wall space or where the door opening needs to accommodate large items, such as freight or hospital beds. Swing doors can be easier to install in non-standard or smaller elevator shafts since they do not require the overhead clearance that sliding doors need for their tracks. Additionally, swing doors can open outward or inward, allowing flexibility in how the space is utilized around the elevator entrance.

While other functions such as aesthetics, energy efficiency, and installation speed are important in the design and operation of elevator systems, they do not capture the primary functional purpose of swing doors. Their ability to effectively facilitate access in various environments is what makes them essential in many elevator designs.
