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.

Concrete screeding machine for tilt-up panels

A concrete screeding device for screeding uncured concrete placed at a support surface includes a screed head having a floating platform, a grade setting device and a vibrating member. The screed head is configured to be positioned at a start of a screeding pass and placed at a surface of placed uncured concrete. A screed moving device is operable to pull the screed head along the surface of the placed uncured concrete. While the screed head is pulled along the surface of the placed uncured concrete and fully supported at the surface of the placed uncured concrete, the floating platform floats on the surface of the placed uncured concrete and the grade setting device adjusts relative to the floating platform to establish a graded surface of the placed uncured concrete at which the vibrating member will move over and along.

Concrete screeding system with floating screed head

A concrete screeding device for screeding uncured concrete placed at a support surface includes a base structure, a rotating base rotatably mounted at the base structure and rotatable relative to the base structure about a first axis of rotation via a first rotating device, an articulating boom comprising multiple boom sections that are pivotable about respective pivot axes via respective actuators. A screed head is rotatably mounted at a distal end of the articulating boom and is rotatable about a second axis of rotation via a second rotating device. With the base structure positioned at the support surface, and with uncured concrete placed at the region, and responsive to a control input, the first rotating device, the actuators and the second rotating device cooperatively operate to move the screed head through multiple screeding passes over and along the uncured concrete to screed the uncured concrete placed at the region.

Concrete screeding system with rotatable base and articulating boom

A concrete screeding device for screeding uncured concrete placed at a support surface includes a screed head having a grade setting device and a vibrating member, and an extendable and retractable boom. A base end of the boom is attached at a base structure and the screed head is supportable at a distal end of the boom. The boom is extendable so as to position the screed head at a distance of at least 20 feet from the base structure, and the screed head is movable between its extended location and the base structure to screed the concrete placed at the support surface.
