Abstract
An extendable truck trailer chassis having a movable rear section or extension. The extension is equipped with a gear rack whose teeth are adapted to mesh with teeth of an idler pinion which is mounted on the main frame and is, in turn, in mesh with a similar gear rack on a cradle carried on the chassis. With the cradle located at the rear of the frame, and the extension in its withdrawn position, the container is at the rear end of the chassis for unloading and loading. The sliding extension is adapted to be moved aft by any desired means to make the chassis longer. As the extension moves aft, its rack activates the pinion and this moves the cradle and its rack forward by a similar distance.
