The disclosed embodiments further provide a system that could be operated by a single individual, including the single individual that is then manually moving the wheelbarrow from the truck to the particular location of the delivery site where the aggregate material is to be finally dispensed. The disclosed systems provide a self-contained mechanical device that is comparatively-easily mountable to the back of a dump truck or other truck bed for use, and is electrically, or electric over hydraulically, powered through the electrical system of the vehicle in order to avoid any need for additional power requirements.
