Which type of ladder is characterized by having a halyard?

The type of ladder that is characterized by having a halyard is the extension ladder, which includes both 20-foot and 35-foot models. These ladders feature a halyard, which is a rope used to raise and lower the fly section of the ladder. This mechanism allows for the extension to be adjusted to various heights, providing versatility and allowing firefighters to access different levels safely.

Extension ladders are commonly used in firefighting operations, as they can be extended to reach high places, such as the tops of buildings or roofs. The halyard is crucial for this function because it facilitates the smooth operation of extending and retracting the ladder sections.

In contrast, a roof ladder is designed for use on roofs and typically has a hook for securing it in place, while an attic ladder is usually a smaller, foldable ladder meant for access to attics, and does not typically have a halyard. Thus, the presence of a halyard is a distinguishing feature of extension ladders, making them effective for various firefighting scenarios.
