What is the term for the rope or cable used to extend or hoist the fly section of an extension ladder?

The term for the rope or cable used to extend or hoist the fly section of an extension ladder is "Halyard." In the context of ladders, the halyard plays a critical role as it is specifically designed to facilitate the raising and lowering of the fly section. Extension ladders consist of two main parts: the base section and the fly section. The halyard is attached to the fly section, allowing firefighters to extend it to reach higher locations safely and effectively.

Understanding the function of the halyard is essential for safe ladder operations, as it directly impacts the maneuverability and stability of the ladder when elevated. The proper handling of the halyard helps ensure that the fly section is securely raised and can be locked into place without the risk of accidental release or collapse.
