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.

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.

Abstract: A wheeled screeding device is movable over a surface of uncured concrete and is operable to level and smooth the uncured concrete surface. The wheeled screeding device includes a wheeled support having a frame portion supported by at least one wheel, with the wheel defining an axis of rotation. A screed head is mounted to the frame portion and is at least partially supportable on an uncured concrete surface. The screed head is pivotable about a pivot axis generally normal to the axis of rotation and relative to the wheel to adjust an angle of the screed head relative to the axis of rotation. The wheeled screeding device is movable in a direction of travel during screeding of the concrete surface and the pivot axis may be generally parallel to the direction of travel of the wheeled screeding device during screeding of the concrete surface.
