What type of door system is commonly used in low-rise elevators?

Hinged or swinging door systems are often used in low-rise elevators due to their simplicity and effectiveness in smaller buildings where space is limited. These doors operate by swinging open and closed, which allows for quick access and can be advantageous in low-rise applications where the elevator serves fewer floors and typically experiences less demand than those in high-rise settings. This can make them easier to operate, especially in residential environments or smaller commercial buildings.

The other door systems, while effective in different scenarios, may not be as practical for low-rise elevators. Sliding door systems are commonly found in higher-rise installations due to their space-saving design but require more complex hardware. Bi-fold doors can be used, but they are less common in low-rise applications because their construction can be more intricate and potentially more expensive, making them less favorable compared to swinging doors. Rotating door systems, however, are not typically utilized in elevators at all, as they are more suited for main building entrances rather than interior elevator access.
