What type of ladder is carried on the apparatus that has two hooks on one end?

The ladder carried on the apparatus with two hooks on one end is specifically designed to be a roof ladder. A roof ladder is often equipped with hooks that allow it to securely latch onto the ridge of a roof, providing a stable platform for firefighters to work from while on a sloped or flat surface. This feature is particularly valuable in firefighting scenarios where stability and safety are paramount.

The hooks allow the ladder to be anchored in place, preventing slippage and offering a robust means of getting personnel safely onto roofs to either perform rescues or suppress fires. The design of the roof ladder distinguishes it from other types of ladders, such as extension ladders, which are primarily used for reaching heights and do not have hooks, or folding and step ladders, which serve different practical applications and are not typically used in firefighting situations.
