ABSTRACT:
A dump truck having a telescoping container body which is initially telescoped to a reduced length to discharge a portion of the load therefrom in response to the telescoping action and thereafter elevated to discharge the remainder of the load in the manner of a conventional dump truck. The fully extended length of the container body, which determines the load carrying capacity of the container body, is greater than that which would normally be elevated to directly discharge the load therefrom in the manner of a conventional dump truck. The retracted length of the container body is no greater than the acceptable length of a container body for elevating to dump a load in a conventional manner. The improvement in a dump truck consists of a container body which has a front section and a back section telescoped one within the other and a first drive mechanism associated with a front section for driving the front section longitudinally of the frame between the extended and retracted positions and a second drive mechanism associated with the back section for moving the back section from its lowered position to its elevated position to dump a load therefrom.
