What is one primary function of elevator doors?

One primary function of elevator doors is to safely enclose the elevator cab when it is not in use. This aspect is crucial for ensuring the safety of users and maintaining the proper functioning of the elevator system. By enclosing the cab, the doors help prevent accidents or injuries that could occur if the elevator were left open, such as someone inadvertently falling into the shaft or accessing the machinery. It also plays a vital role in providing a secure environment within the cab itself, preventing objects or individuals from falling out or getting into the shaft area while the elevator is in motion.

The role of the doors as a safety feature is fundamental to the overall operation and design of elevators, adhering to strict safety regulations and standards that are essential for public use.
