  • Publication number: 20140084566
    Abstract: A vehicle recovery tool is used to tow disabled vehicles. The recovery tool includes a structural member that is mounted on an axle assembly including wheels. The structural member is configured to be coupled to or engage a vehicle to be towed that is positioned behind the recovery tool and to be coupled to or engage a towing vehicle positioned in front of the vehicle. A linear actuator is used to lift the structural member as well as the vehicle to be towed to a raised position. With the structural member in the raised position, the linear actuator further positions the structural member into a locked position in which the load of the vehicle being towed is supported by a control linkage against a stop, preferably on the axle assembly.

  • Patent number: 8662556
    Abstract: This invention provides an apparatus and method for safely lifting large off-highway truck bodies and also allows for lifting these truck bodies inside off-highway truck service bays with limited overhead lifting clearances. The invention minimizes the stresses on the truck body and on the lifting cables/slings. This lifting apparatus and method incorporates temporary lifting eyes installed through lifting hole receivers in the truck body floor. The temporary lifting eyes can be designed such that their strength is gained thru interlocking steel members versus simply welding.

  • Patent number: 8651580
    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.

  • Patent number: 8635754
    Abstract: A method of rebuilding an off-highway truck body by replacing the entire body floor with a replacement body floor specifically built for the intended application of the truck body. Custom-built replacement body floors are thus used to successfully rebuild the off-highway truck body to specific applications with minimum effort.

  • Patent number: 8596705
    Abstract: An apparatus and method is provided for truck bodies to minimize the debris buildup that often occurs on and in truck bodies. Hydrophobic and oleophobic materials are used to coat and protect truck bodies so as to facilitate the release of debris that otherwise might stick to a truck body. If left unchecked, such debris has the net effect of reducing the allowable payload that a truck can effectively carry. Additionally if truck body debris builds up, if not prevented, whenever maintenance work must occur on a truck, for safety reasons any debris buildup on a truck body must be removed prior to any maintenance being performed to preclude any of this debris from falling on maintenance personnel and/or hampering such maintenance.

  • Patent number: 8532867
    Abstract: An apparatus is provided for diagnosing the state of health of a vehicle and for providing the operator of the vehicle with a substantially real-time indication of the efficiency of the vehicle in performing an assigned task with respect to a predetermined goal. A processor on-board the vehicle monitors sensors that provide information regarding the state of health of the vehicle and the amount of work the vehicle has done. In response to anomalies in the data from the sensors, the processor records information that describes events leading up to the occurrence of the anomaly for later analysis that can be used to diagnose the cause of the anomaly. The sensors are also used to prompt the operator of the vehicle to operate the vehicle at optimum efficiency.

  • Publication number: 20130226396
    Abstract: A method for estimating the effective volumetric capacity of a truck body includes 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 the side walls of the truck body and a front-to-rear profile by extending a front load line upward from the upper edge of the front wall and a rear load line upward from at or near a rear edge of the floor at the predetermined material angle of repose. Load plateau lines having predetermined dimensions are established and the height of the plateau lines is determined. A top pro of the generic load is then created and the shape of the load plateau is adjusted into a closed curve shape. A final three-dimensional generic load model is formed and the volume of the load model is calculated.

  • Publication number: 20130112768
    Abstract: A tanker vehicle for distributing liquid on a surface includes a chassis that supports a tank for holding the liquid. A fluid pump discharges the liquid from the tank and is driven by a hydraulic motor. A hydraulic system delivers hydraulic fluid to the motor through a supply line and returns the fluid to a tank through a return line. A bypass circuit is disposed between the supply line and the return line, bypassing the motor. The bypass circuit includes a system for providing a combination soft start and soft stop of the hydraulic motor that is configured to enable hydraulic fluid to flow from the supply line through the bypass circuit to the return line at a start of the hydraulic system and to flow from the return line through the bypass circuit to the supply line at a shutdown of the hydraulic system.

  • Publication number: 20130094936
    Abstract: A truck body designed for transporting hard rock mined ore. The truck body includes a body floor having a first material forming a floor structure and a liner structure including a second material covering at least a portion of the floor structure. The second material has a hardness that is greater than a hardness of the first material and prevents wear of the truck body floor by the hard rock ore. The truck body includes a front wall and two opposing body sidewalls that taper outwardly from front to rear of the truck body such that a width between the body sidewalls at a rear of the truck body is at least 10% greater than a width at the front of the truck body. The outward tapering of the body sidewalls promotes movement of the load away from the body sidewalls as the load is released from the truck body.

  • Patent number: 8280596
    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 track 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. The volume of the final three-dimensional generic load model can then be calculated.
