Abstract: A ladder for a fire truck includes a plurality of telescoping ladder-frame sections, each formed of a pair of spaced side rails having a C-shaped cross section for slidably receiving a corresponding side rail on an adjacent section. Positioned between each of the side rails are a plurality of motorized platforms that are deployable to provide a series of horizontal stairs for ascending the ladder. The platforms may also be inverted until they are parallel with the side rails to form a slide on which a fire victim may easily descend to safety.
