Abstract: A stone slinger option for a standard dump truck includes a swing arm pivotally connectable to the truck's chassis, an elongated frame pivotally connected to the swing arm and mounting an endless conveyor belt therein, and drive means for independently moving the swing arm and the frame. The frame can be moved from a stowed travel position adjacent the truck's chassis, below the dump body, to a rearwardly extending position in which it can receive material from the dump body for delivery to a dump site remote from the truck. The truck can operate in its standard dump mode or as a stone slinger, reducing costs at construction sites since additional, specialized stone slinger delivery vehicles will not be required.
