  • Patent number: 9926674
    Abstract: The present invention relates to a method for controlling a construction machine which performs a working operation along a working trajectory on a ground depending on at least one operating parameter. A method according to the present invention comprises placing at least one mark, detectable by a sensor device, stationary on the ground in a region which, regarded from at least one position of the construction machine on the working trajectory, is located in the detection region of the sensor device. The mark is detected by the sensor device, resulting in the generation of sensor data which is processed by the data processing device of the construction machine. A control command is generated for the machine control of the construction machine for changing at least one operating parameter of the construction machine.

  • Patent number: 8308394
    Abstract: Embodiments of the present invention relate to systems and methods implemented in a pothole patching system for creating a vacuum that pulls heavy particulate, such as gravel, out of a hopper. For example, according to an embodiment, a vacuum body having a vacuum chamber formed therein is positioned proximate to an opening of the hopper. A moveable slide gate is provided between the vacuum chamber and the opening of the hopper. The slide gate moves between open and closed positions for permitting and blocking communication between the vacuum chamber and the hopper. A reduction nozzle is provided between an air source and the vacuum chamber. Forced air flows from the air source, through the reduction nozzle, and into the vacuum chamber. The reduction nozzle reduces the pressure of the forced air entering the vacuum chamber, and thereby creates a vacuum in the vacuum chamber. When the slide gate is in the open position, this vacuum pulls particulate from the hopper.

  • Patent number: 8221027
    Abstract: A powered roller screed (366) is disclosed, that uses a dual-drive power unit (370) and a screed roller (368). A power source (372) of the dual-drive power unit (370) includes a first drive output (374) and a second drive output (376), which rotate in the same direction and at the same rate. Each of the first drive output (374) and the second drive output (376) may be used to rotate the screed roller (368). For instance, the first drive output (374) could be attached to a first end of the screed roller (368), or the second drive output (376) could be attached to the second end of the screed roller (368), all to rotate the screed roller (368) in the same direction as the screed roller (368) is being pulled over wet concrete (364).

  • Publication number: 20120163913
    Abstract: The invention provides a variable width material distribution apparatus for use with an asphalt paving machine for distributing asphalt screed across a surface to be paved. The apparatus comprises at least two auger support members and at least two auger slide sections such that extension or retraction of the auger support members along a path of least resistance as the apparatus moves over a surface to be paved causes a corresponding extension or retraction of the auger slide sections with respect to an adjacent auger slide section and such that each auger slide section is configured to maintain a continuous worm with respect to an adjacent auger slide section when in an extended position in relation to one another.

  • 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.

  • Publication number: 20110222966
    Abstract: High performance, multiple rotor, hydraulically driven riding trowels for finishing concrete have unloader valve circuitry for controlling hydraulic pressure. Each trowel has a rigid frame with two or more downwardly-projecting, bladed rotor assemblies that finish concrete. The rotor assemblies are tilted manually or hydraulically to effectuate steering and control. Blade pitch is controlled manually or hydraulically. The unloader valve system monitors drive pump pressure with a shuttle valve to derive an unloader pilot signal. A sequence valve responds to the unloader pilot signal to control a pressure valve that bypasses the normal foot control valve in an overpressure situation. The pressure control head signal normally applied to the hydraulic drive motor control heads is modified with a feedback signal to automatically control the associated pump swash plates. A gearbox may be disposed between the drive motors and rotors. Piston type and gear and vane type motors may power the rotors.

  • Publication number: 20110200389
    Abstract: Embodiments of the present invention relate to systems and methods implemented in a pothole patching system for creating a vacuum that pulls heavy particulate, such as gravel, out of a hopper. For example, according to an embodiment, a vacuum body having a vacuum chamber formed therein is positioned proximate to an opening of the hopper. A moveable slide gate is provided between the vacuum chamber and the opening of the hopper. The slide gate moves between open and closed positions for permitting and blocking communication between the vacuum chamber and the hopper. A reduction nozzle is provided between an air source and the vacuum chamber. Forced air flows from the air source, through the reduction nozzle, and into the vacuum chamber. The reduction nozzle reduces the pressure of the forced air entering the vacuum chamber, and thereby creates a vacuum in the vacuum chamber. When the slide gate is in the open position, this vacuum pulls particulate from the hopper.
