What is a common type of door used in passenger elevators?

The selection of sliding doors as a common type of door used in passenger elevators is based on their design and functionality. Sliding doors are favored for their space efficiency, as they do not require additional space to swing open, making them ideal for areas where real estate is limited. This design also contributes to a smooth and safe operation, enhancing the overall user experience within the elevator.

These doors can be seen in various elevator models because they provide a reliable barrier while allowing for quick access in and out of the elevator compartment. Moreover, additional safety features, such as door sensors and motion detectors, are often incorporated into sliding doors to prevent accidents and ensure user safety.

In contrast, other door types like folding, revolving, or automatic swing doors are less commonly utilized in passenger elevators. Folding doors, while compact, tend to be less durable and can take longer to open and close. Revolving doors are not practical in elevator applications due to their continuous motion and the requirement for a revolving system that is incompatible with the needs of elevator access. Automatic swing doors, while useful in certain environments, do not offer the same space-saving benefits as sliding doors and are not typically designed for vertical movement like elevators.
