  • Patent number: 6000741
    Abstract: A liner for a body such as of an off-highway truck protects the body from wear. The liner has a plate with openings through the plate arranged in a preselected pattern. The plate is of a size to fit a particular portion of the body and is typically removably fastened to the body. The openings in the plate cause material to tumble, instead of to slide, when being removed from the truck. The tumbling action, and the thickness of the plate, reduces wear on the body during material dumping.

  • Patent number: 5797657
    Abstract: A truck includes a chassis with a body movably mounted to the chassis behind a cab. The body is movable between a first position generally parallel to the chassis and a second generally upright position with respect to the chassis. A canopy is movably mounted to the body. The canopy is movable between an extended position and a retracted position. In the extended position, the canopy extends outwardly from the body to cover the cab when said body is in the first position.

  • Patent number: 5454620
    Abstract: An ultralight yet extremely strong vessel without a circumferential support suitable for full-length, end-dumpable trailers, for railroad tank cars, highway tank trailer, refuse transportation vehicles and the like. High strength and minimum weight are achieved by arcuately stressing but light materials, by provision of longitudinal support members which may become an integral part of the vessel and, in open-top embodiments, by provision of a reinforcing member along an extended open edge of adequate horizontal moment of inertia and which may readily be pre-tensioned if desired. In the pre-tensioned embodiment, such to reinforcing member may cause the open-top vessel to bow inwardly before loading so as to compensate for the outward-tendency of such vessels constructed of elastic materials when loaded.

  • Patent number: 5435627
    Abstract: The invention is a multipurpose adaptor box for a dump truck designed to fit into the dump truck box of a dump truck. The adaptor box has an exterior surface that surrounds an interior chamber so that the box defines essentially a bottom and four sides with an open top. The rear side of the adaptor box (i.e. the tailgate) includes a door means for providing access to the interior chamber. The door is swing mounted on hinges to the exterior surface of the adaptor box and has an opening passing through it that is designed to allow a leaf blower system to be attached to the adaptor box so that lawn refuse can easily be loaded into the adaptor box when desired. A removable opening cover, capable of being mounted to the door, is provided for covering the opening when it is not needed. The open top of the adaptor box is defined by the top edges of the side walls. A grate is used to cover the top opening to the adaptor box.

  • Patent number: 5090773
    Abstract: A new mode of construction for vehicles having a dump body comprises a container (6) which rests on a fixed cradle (5) that serves as a chassis (1). The lower portion of the container (6) is adapted to be interfitted in the cradle due to the fact that the section of the cradle corresponds to the section of the lower portion (10) of the container of smaller dimensions, so as to permit the interfitting of the container in the cradle. The container and the cradle are constituted by volumes having substantially concentric transverse sections such that the lower portion (10) of the container precisely interfits in the cradle.

  • Patent number: 4988258
    Abstract: A car catcher apparatus is provided which is pivotally mounted to an elevated chassis, a flatbed, or other related structure which protrudes rearwardly beyond the rear wheels of a vehicle such as, for example, a truck. The car catcher includes a frame-like structure which is positioned by an actuator to a raised inoperative position and a lowered operative position. In the lowered operative position, the car catcher is in position to receive impact from automobiles, or the like, during collisions therewith. The car catcher apparatus has particular use with rearwardly-protruding truck structure which is periodically intended to be pivotally lowered to a position at or near ground level. When in the raised inoperative position, the car catcher permits complete and unrestricted downward pivoting of such structure. Furthermore, when positioned the raised inoperative position, the car catcher apparatus permits ready access to the rear wheels, axles, suspension, etc.

  • Patent number: 4940287
    Abstract: Apparatus which enhances the load carrying capacity of a dump truck without interfering with dumping of the dump bed. A rigid frame which is added to the back end of the truck includes a beam carrying an axle and a pair of wheels. A hydraulic cylinder pivots the beam between a load bearings position in which the wheels travel on the roadway to bear part of the dump bed load and a raised position in which the beam extends vertically between a pair of side by side tail gates. A hinged door operates in the space between the two tail gates to prevent spillage of the load through the space while accommodating extension of the beam through the space when the dump bed is raised to dump its load. A diverter in the dump bed deflects material away from the space and toward the tail gate openings.

  • Patent number: 4580843
    Abstract: A bale rack comprises an elongate horizontal frame mounted on wheels for movement along the ground, and a pair of bale supports extending along opposite sides of the frame. The bale supports are pivotable relative to the frame between a raised position, in which the bale supports serve to retain bales on the frame, and a load release position, in which the bale supports are downwardly and laterally inclined from the frame to allow a bale to roll from the frame to the ground. Latch mechanisms are provided for releasably retaining the bale supports in the raised positions, and counterweights are provided for urging the bale supports from the lowered positions to the raised positions, thus avoiding the use of springs, hydraulic devices or other relatively complicated mechanisms for this purpose.

  • Patent number: 4116486
    Abstract: A retractable rock guard for the dump body of a truck, comprising a protective structure which is normally in the upright position at the front of the dump body. The protective structure is pivotally connected to the dump body but ordinarily is secured in the normal upright position by detachable connectors. However, it can be readily detached and then the protective structure can be retracted by raising the dump body to a dump position in the usual manner. The upright protective structure is constructed and arranged so that its center of mass passes through a vertical plane intersecting its pivotal connection on the dump body under these circumstances and when this occurs the proctective structure moves to a horizontally disposed retracted position on the truck body.

  • Patent number: 4084851
    Abstract: A self-dumping self-retracting cargo bin adapted for installation in a conventional pickup truck without need for tools or alteration of the truck. The bin has front and rear roller means for supporting the bin on a loading dock or the like when not in a truck. When mounted in a truck, the rear end of the bin is supported on fulcrum rollers carried by a latching sub-assembly extending crosswise of the truck body with latch means positively embracing the truck's rear stake sockets. The bin is self-dumping when its rear doors are unlocked and it is released from its travel mode merely by starting the truck forward abruptly. Energy stored in heavy duty retraction springs during the dumping cycle is effective to restore the bin toward its travel mode.
