  • Expanded size sludge vacuum tanker
    Patent number: 8328290
    Abstract: An extendable mobile fluid carrying apparatus including a first frame configured to couple to a tractor. A fluid container is coupled to the first frame and configured to rotate about a pivot device of the first frame. The container defines a closable orifice configured to decant a fluid from the container. A high-CFM blower is coupled to the container and configured to draw a vacuum. A lift mechanism is coupled to the first frame and the fluid container and configured to lift the fluid container to an angle greater than 45° relative to the first frame. A second frame is slidingly coupled to the first frame, with the second frame configured to extend away from the first frame a predetermined distance. The second frame includes a wheel set. The tractor may include a power takeoff mechanism coupled to a prime mover and to the blower.
