In a partial strut installation, whose responsibility is it to carry the weight of the doors?

In a partial strut installation, the header is responsible for carrying the weight of the doors. The header serves as a structural component that supports the door assembly, ensuring that the weight is properly distributed and that the doors operate smoothly. It is designed to handle the load imposed by the doors, which is crucial for maintaining functionality and safety in an elevator system.

Understanding the role of the header in this context is essential, as it directly affects the performance of the elevator door mechanism. A sturdy and appropriately sized header will accommodate any stress and load from the doors, reducing the risk of operational issues or failure. This is particularly important in a partial strut installation where the structural support relies on various components working correctly together.

In contrast, other elements like the footer, walls, or frame have different responsibilities in the overall installation. The footer primarily supports the lower structure, while the frame provides the overall support and shape for the door assembly. The walls, on the other hand, create the surrounding environment but do not directly support the weight of the doors. Understanding these distinctions helps in grasping the importance of each component's role in elevator installation.
