Methods and systems for making and using a wide swath offset concrete screed apparatus for screeding wet concrete slurry. The apparatus includes a cross support bar, an attachment mechanism for attaching the cross support bar to a liftable arm of a motorized vehicle, and a roller screed attached to the cross support bar. The roller screed is positioned offset from the motorized vehicle used to operate the screed, allowing the motorized vehicle to drive outside the forms.

Methods and systems for making and using a wide swath offset concrete screed apparatus for screeding wet concrete slurry. The apparatus includes a cross support bar, an attachment mechanism for attaching the cross support bar to a liftable arm of a motorized vehicle, and lateral support bars for attaching a screed bar to the cross support bar. The screed bar is positioned offset from the motorized vehicle used to operate the screed, allowing the motorized vehicle to drive outside the forms.

A screed arrangement includes a screed assembly (1) for laying a road surface (3), the screed assembly (1) configured to determine a working width (W), viewed in the working direction (R), for laying of the road surface (3). The screed arrangement further includes a working station (9) for an operator (P) mounted on the screed assembly (1). The working station (9) is mounted on the screed assembly (1) in a vibration-decoupled manner, such that the transmission of vibrations from the screed assembly (1) to the working station (9) an be reduced or prevented.

A screeding machine for screeding uncured concrete includes a base unit positionable at a support surface, and a screed head assembly movably mounted at the base unit. The screed head assembly includes (i) a grade establishing member and (ii) a vibrating member. Elevation actuators are operable to adjust elevation of the screed head assembly responsive at least in part to elevation sensors that sense elevation of respective ends of the screed head assembly. A control system, responsive to signals from the elevation sensors, controls the elevation actuators to set the grade of the uncured concrete. The screed head assembly is positionable at a screeding location and is movable over the uncured concrete in a screeding direction to screed the concrete. A sensor senses the surface of the screeded concrete and generates an output. The output of the sensor is processed to determine a quality level of the screeded concrete surface.

This application is for an improved paver head for smoothing and finishing poured concrete surfaces. It includes a strike-off plow for initial leveling of concrete, an auger for mixing and smoothing surface imperfections, a roller for smoothing and leveling, and a finish blade for final surface finishing of a poured concrete surface.

The disclosure relates to a screed assembly for laying a road surface, said assembly determining a working width, viewed in the working direction, for laying of the road surface, and a working station for an operator being mounted on the screed assembly. The working station is mounted on the screed assembly in a vibration-decoupled manner, such that the transmission of vibrations from the screed assembly to the working station can be reduced or prevented.

An implement for working uncured concrete includes a removable manipulator and a tool for engaging the surface of uncured concrete. The implement is configured to permit manipulators to be interchanged such that the appropriate manipulate or may be used to perform a particular task during the concrete curing process.
