  • Patent number: 9718502
    Abstract: An air fairing device is connected below the bottom a frameless trailer to improve aerodynamic efficiency and improve fuel economy. One embodiment of the air fairing device provides an air deflector positioned forward of a trolley which supports the frameless trailer at a rear end. A second embodiment of the air fairing device provides two deflectors mounted below the frameless trailer. The first deflector is attached and extends downward from an articulating arm, said arm connecting the trailer to a semi-tractor or truck. The second deflector connected to below the bottom of the frameless trailer and positioned rear of the first deflector and forward of the trolley. A third embodiment is similar to the second but further includes a third deflector positioned between two axles of the trolley.

  • Patent number: 9573509
    Abstract: A deck for a truck or trailer has a base frame and a deck frame movable relative to the base frame to either one of a tilt position or a dump position. A first pivot connection between the frames defines the pivot axis of the tilt position while a second pivot connection separate and spaced from the first pivot connection defines the pivot axis of the dump position. A common lift mechanism between the frames lifts the deck frame to either one of the tilt or dump positions depending upon the operative condition of the first and second pivot connections.

  • Patent number: 9365148
    Abstract: A truck body includes a front wall, side walls, and a floor. The floor has panels disposed at predetermined angles from the horizontal that, with the other parts of the body, form a payload volume within the body. The floor also includes a tail panel disposed at a lesser angle from the horizontal to facilitate the shedding of the payload when dumping, and further to maintain the center of mass of the payload in a generally forward position during dumping.

  • Patent number: 8417425
    Abstract: An apparatus for improving the stability of a payload of granular material loaded onto the bed of a vehicle that will traverse at least one grade is disclosed. The bed of the vehicle may be coupled to a hoist mechanism which may be linked to a controller with a memory for entering a value for the grade the vehicle may traverse while carrying the payload on the bed. The controller may send a signal to the hoist mechanism to tilt the bed to a tilted position having an angle about the value of the grade. An optional tilt support mechanism may be used to engage and support the bed after the bed has been tilted by the hoist mechanism to support the bed in the tilted position while the bed is loaded with the granular material. The hoist mechanism can be used to move the bed back to the horizontal position after the payload has been deposited on the bed.

  • Patent number: 8215717
    Abstract: A towable dump trailer is provided. The towable dump trailer comprises a first, second and third frame. The first frame comprises one or more sets of wheels. The second frame is attached to the tow vehicle and can be displaced horizontally relative to the first frame by the towing vehicle moving rearward or forward. The third frame provides a support frame for the trailer bed. The dump trailer is operated by immobilizing the first frame and causing the second frame to move horizontally relative to the first frame. This horizontal displacement causes the third frame to pivot as a result of one or more pivoting arms translating the horizontal movement to pivotal movement. The dump trailer can be configured to provide a dumping action by either forward or rearward horizontal displacement of the second frame relative to the first frame.

  • Patent number: 6527494
    Abstract: A frame configuration that is particularly adaptable for use on a trailer such that the frame configuration is operable in both a tilt mode of operation and a dump mode of operation. An actuating mechanism includes a linear actuator that is supported on the frame by a bracket and a yoke that connects to a load bed to power the vertical movement of the load bed in both tilt and dump functions. The linear actuator is pivotally mounted to permit a re-positioning of the actuator into an inoperative position. The frame configuration is provided with an articulated tilt frame in which the tongue is pivoted thereto allowing the load bed to pivot about a tilt axis which can coincide with the wheel axis of the trailer. The bed frame can be locked to the tilt frame for tilting upon articulation with the tongue, while a disconnection of the bed frame from the tilt frame enables the bed frame to pivot about the dump axis to provide a dump function in addition to the tilt function.
