摘要:
A wheeled screeding device includes a wheeled support having a frame portion supported by at least one wheel, with the at least one wheel defining an axis of rotation. A screed head is mounted to the frame portion and is balanced such that the screed head is at least partially supportable on an uncured concrete surface. The screed head is adapted to impart a force onto the uncured concrete surface. An adjustment device may be operable to adjust a balance of the wheeled support about the axis of rotation to adjust the force imparted by the screed head. The screed head may be pivotable about an axis generally normal to the axis of rotation of the wheel and relative to the at least one wheel to adjust an angle of the screed head relative to the axis of rotation of the wheel.
