Abstract: A screeding machine includes a base unit positionable at framework that defines a concrete structure and a screed head assembly movably mounted at the base via an extendable and retractable mechanism. The screed head assembly includes a grade establishing member, a vibrating member, and elevation actuators for adjusting elevation of the screed head assembly. The screed head assembly is positioned at a screeding location via extension of the extendable and retractable mechanism and is movable over the uncured concrete in a screeding direction via retraction of the extendable and retractable mechanism. Adjustable wings disposed at and in front of the grade establishing member in the screeding direction are movable along the grade establishing member. When one of the ends of the screed head assembly is positioned at a frame portion, the wing at that end of the screed head assembly is moved to position the wing at the frame portion.

Abstract: A concrete surface working machine includes a base portion and a screed head mounted at the base portion. The screed head includes a grade setting device and a vibrating element attached at a frame of the screed head. The screed head includes a rock tamper adjustably attached at the frame of the screed head via a pair of support elements. The screed head includes a pair of actuators that, when actuated, adjust the support elements to adjust the rock tamper relative to the frame. The concrete surface working machine is operable to position the vibrating element at the concrete surface. The actuators are selectively controlled by an operator of the concrete surface working machine to adjust a height of the rock tamper relative to the vibrating element and the concrete surface while the screed head is moved along the concrete surface.

Abstract: A screeding machine for screeding uncured concrete includes a base unit, a support mechanism disposed at an end portion of the base unit, and a screed head assembly supported at the support mechanism. The screed head assembly includes (i) a grade establishing member and (ii) a vibrating member.

A control system is operable to control the lateral actuator to laterally shift the screed head assembly in the direction orthogonal to the longitudinal axis of the base unit to move the screed head assembly toward a wall or structure while the screeding machine moves over uncured concrete in a screeding direction via movement of the base unit along the uncured concrete and alongside the wall or structure.

Abstract: A concrete finishing machine includes a base portion and an extendable and retractable boom mounted at the base portion, and a finishing head mounted at a distal end of the boom. The finishing head includes (i) a float pivotally attached at a frame of the finishing head via a plurality of linkages, (ii) a float actuator that, when actuated, imparts pivotal movement of the linkages to adjust the float relative to the frame, and (iii) a surface finishing element. The concrete finishing machine is operable to selectively position the float or the surface finishing element at the concrete surface during extension or retraction of the boom. Responsive to a sensing device, the finishing head is maintained at a desired level or position above the concrete surface with the float or the surface finishing element at the concrete surface during extension or retraction of the boom.

Abstract: A method of establishing a desired grade of an uncured concrete surface or subgrade surface includes providing a wheeled apparatus having a wheeled support and a plow assembly, which may include a plow member for establishing the desired grade and/or a vibrating member for vibrating and smoothing the concrete. The down pressure of the plow assembly may be adjusted when the wheeled support is moved in a rearward direction. The elevation of the plow member may be controlled when a direction signal is indicative of the wheeled support stopping and/or moving in the forward direction. The rearward speed of the wheeled support may be reduced in response to a detection of a surface irregularity of the subgrade, and the frame portion and/or the plow assembly may be controlled to substantially maintain the plow assembly at a desired orientation when the wheel engages the detected surface irregularity.
