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

The term for the rope or cable used to hoist the fly section of a ladder is "halyard." In ladder operations, the halyard is specifically designed to raise and lower the fly section, which is the part of the ladder that extends to increase its reach. Understanding the purpose of the halyard is crucial for effective ladder use in firefighting, as it provides the necessary support and control when operating the ladder at elevated heights.

The other options refer to different concepts. A guide line is often used to help stabilize ladders or provide direction during deployment. A safety line typically refers to a secondary line used to secure personnel working at heights, while a support cable may be associated with the structural integrity of devices or temporary installations, rather than with ladder operations directly. Recognizing these distinctions is important for proper terminology and safety protocols in firefighting scenarios.
