Which part of an extension or combination ladder is the section that moves?

The fly section of an extension or combination ladder is designed to be the part that moves, allowing the ladder to extend to various lengths. This section is adjustable and typically slides out from the base section, giving firefighters the ability to reach higher or more difficult areas while maintaining stability.

The functionality of the fly section is crucial during fire rescue operations or when accessing elevated locations, as it allows for a greater range of height without needing to replace the entire ladder. Its design ensures that it can be easily maneuvered while still being secure when locked in place.

Understanding the role of the fly section is essential for proper ladder handling and usage, ensuring that firefighters can effectively and safely deploy ladders during emergency situations.
