  • Patent number: 8371769
    Abstract: A control and a method of control for a machine that applies a material to a subgrade at a work site and pulls a floating screed, having a screed plate, over the top surface of the material behind the machine is useful in paving with asphalt material. The floating screed is attached to the machine by a tow arm at a tow point on said tow arm. The vertical height of the tow point is controlled by an hydraulic cylinder on said machine in response to a valve control signal applied to an hydraulic valve by a valve control drive. The screed determines the thickness of the material on the subgrade and is manipulated by adjusting the height of the tow point. A first sensor is mounted on the floating screed for sensing three-dimensional position. A second sensor for senses the pitch of said screed. A processor circuit is responsive to the first and second sensors for determining the height of the trailing edge of the screed plate and the movement of the screed over the top surface of the material.

  • Patent number: 8070385
    Abstract: A control is provided for a machine that applies a material to a subgrade and pulls a floating screed over the top surface of the material behind the machine. The floating screed is attached to the machine by at least one tow arm at a tow point on the tow arm. The vertical height of the tow point is controlled by a hydraulic cylinder on the machine in response to a valve control signal applied to a hydraulic valve. The screed determines the thickness of the material on the subgrade as it is manipulated by adjusting the height of the tow point such that the top surface of the material follows a reference surface. A first sensor is mounted on the machine, adjacent the front of the machine, for sensing the relative height of the reference surface and providing a first sensor output related thereto. A second sensor for senses the height of the tow point relative to the machine and provides a second sensor output related thereto.

  • Patent number: 8052347
    Abstract: A floating screed device has a first section for cutting through plastic concrete and a second section for floating on the plastic concrete. The two sections are pivotally coupled for rotational movement about a pivot point. Elevation of the second section is measured and used to rotate the first section as the floating screed device is moved through a volume of the plastic concrete that is unfinished. As a result, the second section pitches to follow the first section.

  • Patent number: 8038366
    Abstract: A wheeled concrete screeding device includes a wheeled unit having wheels for movably supporting a frame portion, and a screed head supported at the frame portion and following behind the wheeled unit when the wheeled unit is moved in a screeding direction. The screed head includes a grade establishing element and a vibratable member. The grade establishing element is generally vertically adjustable responsive to a signal from a laser receiver disposed at the screed head to establish a struck-off surface of the uncured concrete at a desired grade. The vibratable member is adjustably attached at the grade establishing element and the vibratable member at least partially floats behind the grade establishing element on the struck-off surface of the uncured concrete and is at least partially supported at the struck-off surface of the uncured concrete as the wheeled unit is moved in the screeding direction.

  • Patent number: 8038365
    Abstract: A soft landing control system for a screeding device is operable to automatically lower a vibrating member relative to a grade setting device after the grade setting device is lowered to the desired grade. The control may be operable to delay lowering the vibrating member relative to the grade setting device at least until the control receives an input indicative of at least a portion of the screed head assembly being moved to a position generally over a newly placed concrete area.

  • Publication number: 20110243662
    Abstract: A road repair tractor adapted for smoothing asphalt that has been laid into a work-trench, dug in a roadway. The tractor includes a body supporting an engine and defining a cockpit. Also, laterally spaced first and second support and motive force assemblies are operatively driven by the engine and support the body. A smoothing device is supported by the body and has a width that is adjustable from a most narrow width of between 40 cm and 80 cm to a widest width of between 1 meter and 2.5 meters. The smoothing device also includes a smoothing blade assembly, having a bottom edge, deployed between a pair of asphalt side-spill guards. Finally, a power actuating system includes controls located in the cockpit that permit a user seated in the cockpit to change the adjustable width of the smoothing device and to raise and lower the smoothing device relative to the body.

  • Publication number: 20110123269
    Abstract: An improved screed plate having a top surface, a bottom surface, a curved leading edge and a trailing edge adapted for attaching to a screed of a paving machine is disclosed. The improved screed plate comprises a tapered groove extended from the curved leading edge towards the trailing edge along the top surface and terminated in a groove end. The tapered groove is arranged deepest at the curved leading edge and shallowest toward the trailing edge so as to provide flexibility to the screed plate while not reducing screed plate lifetime due to increased wear and tear. The increased screed plate flexibility facilitates crowning and other adjustments that require bending of the screed plate, and allow harder steels to be used than are used in conventional screed plates.
