What is a key consideration when installing elevator entrance doors?

When installing elevator entrance doors, proper alignment and leveling of the door frame with the elevator shaft is crucial. This ensures that the doors operate smoothly and securely, preventing any malfunctions that could lead to safety hazards. Proper alignment is essential for the doors to open and close correctly, providing a safe and accessible entry point for passengers. Misalignment can cause issues such as door jams, uneven gaps, or improper sealing, which could also affect the overall performance of the elevator system.

While considerations such as color coordination, durability of materials, and cost are important aspects of the installation process, they do not directly impact the immediate functionality and safety of the door operations as alignment and leveling do. Ensuring that the door frame is aligned with the shaft creates a reliable and safe environment for the elevator to operate.
