  • Patent number: 6328522
    Abstract: A method and apparatus for collecting and transferring refuse to a transportation truck for hauling to its ultimate disposal site, such as a landfill. The apparatus comprises a refuse collection and transfer container movable between a first, lowered position and a second, raised position. When the container is in the raised position and the transportation truck is underneath, transfer of the collected refuse is accomplished by opening angled, retractable bottom doors on the container. The bottom doors allow for the regulation of the amount of refuse transferred to the truck, thus ensuring a full load within the truck while at the same time preventing spillage. The movement of the container and the doors may be powered by the hydraulic system of the truck and controlled by a control panel on the apparatus. The apparatus may be partially below ground level.
