  • Publication number: 20110204697
    Abstract: The dump box system includes a dump box that rolls along the length of the pickup truck bed. The movement of the dump box is controlled by a hoist system attached to the truck bed. The hoist system has a pair of reels in spaced relation along a drive shaft. The drive shaft is turned by a crank-operated winch unit so that straps coiled on the reels are reeled in or paid out. The dump box can be moved from a position wherein it is completely encased within the truck bed to a position where it is tilted and hanging out through the rear opening of the truck bed. The design of the dump box system allows the user to quickly unload large quantities of debris and other materials from the truck without the need for resort to shovels or rakes.

  • Patent number: 5720526
    Abstract: A device and method for locking a slidable and tiltable truck bed against tilting when the truck bed is in the forward position adjacent the truck cab are presented. The device includes a movable actuator that communicates with the truck's hydraulic system to effect tilting. If this actuator is prevented from moving, the tilting function cannot be accessed. The actuator is locked by restraining its top end between two tabs at one end of a hinge. A spring positioned between a fixed support, to which is also affixed the other end of the hinge, and one of the tabs, in the absence of compression, permits the actuator free motion; upon a forward sliding of the truck bed, however, the spring is compressed, moving the tabs downward to engage and restrain the actuator top end.

    Abstract: A carrier vehicle, for carrying at least one vehicle on a carrier bed which is slidable and tiltable relative to the carrier vehicle's frame, includes a tilt lock-out arrangement for preventing actuation of the carrier vehicle's tilt cylinders whenever the moveable carrier bed is locked in a stowed, or vehicle carrying position. The lock-out arrangement features a contactless sensor element which determines the slidable position of the movable carrier bed and inhibits hydraulic activation of the tilt cylinders to raise or lower the carrier bed unless the carrier bed has first been slid rearwardly to clear a mechanical hold-down element. Similarly, the contactless sensor element inhibits hydraulic actuation of the tilt cylinder to lower the carrier bed unless the bed has cleared the hold-down element.

    Abstract: A trailer body (600) and pedestal (604) are provided where the pedestal supports an axle assembly (605) which is pivotally secured to the pedestal so that when the pedestal is in the forward position to permit trailer dumping, the axle assembly pivots about the pedestal to keep all wheels (612) on the ground. A safety plate (630) can be mounted between a frame and pedestal to prevent structure from being wedged between the transverse beams of the frame and pedestal as the pedestal slides relative to the frame. Also, a striker plate (616) is employed to prevent a locking wedge (622) from interfering with movement of the pedestal relative to the frame until the pedestal is either in the rearward position or in the forward position. A fender structure (614) is provided which acts as a fender when the pedestal is in the rearward position, but is not damaged as the pedestal moves to the forward position.

  • Patent number: 4673328
    Abstract: A lift/tilt-bed trailer. Apparatus is described for either raising from or lowering to the ground a trailer bed in a single step while maintaining a substantially horizontal attitude relative thereto, or for tilting the trailer bed which is normally positioned parallel to the ground when the trailer is in its traveling mode for the purpose of loading or unloading the bed without substantial change in the orientation of the trailer "U"-frame in which the bed is located. Four pivotable tracks attached to the frame and corresponding roller wheels attached to the bed cooperate to achieve the desired motion. Since the trailer need not be detached from whatever device is used to move it about when it is to be loaded or unloaded, increased stability results with consequent reduction in risk to the operator.

  • Patent number: 4548541
    Abstract: A method and apparatus for loading of a piece of equipment on a lorry. The apparatus includes an arm pivotally interconnected with the lorry and a first jack interposed the lorry and the arm. A jib is telescopically interconnected with the arm. A movable platform is interconnected with a hook on the jib. A cable passes over a pulley interconnected with the movable platform and is hooked to the chassis at one of its ends and to the piece of equipment at the other of its ends. The method includes the steps of moving the piece of equipment rearwardly along the movable platform, the movement of the piece of equipment therealong acting through the cable and pulley to displace the movable platform rearwardly relative to the lorry until the movable platform and the piece of equipment are displaced to a position wherein they are unbalanced on the lorry. Gravity is then used to permit the lowering, by a tilting action, of the movable platform.

  • Patent number: 4384816
    Abstract: In a dump truck, the most efficient way of raising the container body is to apply a lifting force to the end of the body remote from the pivot point. In some applications it is difficult to do so because of height restrictions and it is particularly difficult to do so in a telescoping container body in which the end of the container body which is remote from the pivot point moves in relation to the pivot point. The present invention overcomes this difficulty by mounting the extensible ram in a position remote from its upright position and providing a mechanism for pivoting it to its required upright position prior to its operation as a hoist. In a telescopic container body, the extensible ram is normally stored in freeboard space disposed below the front section of the container body and is raised into an upright position at the front end of the telescoped body in response to movement of the front section from its extended position to its retracted position.

  • Patent number: 4350469
    Abstract: The device comprises a derrick with a main telescopic arm and an auxiliary arm. The telescopic arm 9 is pivoted on a sub-frame which in turn is pivoted to the main chassis of the vehicle. At the front the main vehicle chassis 3 is mounted a cam having ramps 20 and 21 on which travels a roller mounted to the free end of the telescopic arm. In order to tip the load on the vehicle, the telescopic arm is first contracted, providing a slight upward swing of the arm when the roller 22 climbs the ramp 20. This appreciably relieves the load requirements of the tilting jack thereby enabling handling of larger loads.
