  • Publication number: 20120207581
    Abstract: A truck body that efficiently hauls oil sands, which typically coagulate and adhere together in one consolidated mass. The adhesion of this consolidated mass to the surface of the truck body is minimized and the buildup of “carryback” is effectively prevented during haul cycles. Hauled amalgamated materials are dumped from the truck body such that the amalgamation breaks down and is safely dumped. One typical material that displays such a coagulated conglomerate massing is “oil sands” from which oil is extracted. A non-stick surface is provided on the truck body to overcome the natural adhesiveness displayed by this material and, when being dumped from a truck body, provides a means to assist in releasing the material from the truck body without leaving significant “carryback” that tends to buildup over haul cycles. Plus, the body design encourages the material to break down as it is dumped.

  • Publication number: 20120201647
    Abstract: A method is provided for loading material into a dump body of a truck using a loading bucket whose volumetric capacity is approximately ? or more than that of the dump body. The loading bucket is filed with an amount of earthen material and centered over the dump body. The bucket is then lowered to a position that: (1) substantially minimizes the clearance between the floor of the dump body and a swinging gate of the loading bucket in its freed position: (2) allows the swinging gate to clear the side wails of the dump body as it swings through an are after it is freed, and (3) allows the material to be discharged substantially in the center of the dump body. After it is positioned, the swinging gate is then freed so as to release the material held in the bucket.

  • Publication number: 20110257946
    Abstract: A method for estimating the effective volumetric capacity of a truck body is provided. The method includes the step of establishing a side-to-side profile of a generic load model by extending load side lines upward at a predetermined material angle of repose from the upper edge of each of the side walls of the truck body. A front-to-rear profile of the generic load model is also established by extending a front load line upward from the upper edge of the front wall of the truck body at the predetermined material angle of repose and a rear load line upward from at or near a rear edge of the floor of the truck body at the predetermined material angle of repose. Load plateau lines having predetermined dimensions are established in the front-to-rear and side-to-side profiles and the height of the plateau lines are determined. A top profile of the generic load is then created from the side-to-side and front-to-rear profiles and the shape of the load plateau is adjusted into a closed curve shape.

  • Publication number: 20080298941
    Abstract: Loads carried by a haulage vehicle are transferred from the vehicle to a container in a manner that maintains an ordered segmentation of materials comprising each of the loads, where each segment comprises a different type of material. The container receives the load such that each segment forms a layer in the container, which in the case of a charge bucket for feeding an electric arc furnace creates a layering of the different types of material according to a desired recipe for melting scrap metal processed by the mill incorporating the furnace. The transferring of the load is implemented by a haulage truck having a rear eject body whose ejector blade pushes the segmented load out and into the container.
