A concrete finishing system may include a surface sensor, a depiction generator for generating a depiction of a profile of the concrete surface, and a display for displaying the depiction. The system may be used to perform a method of finishing concrete including arranging a surface sensor such that a work area for placement of the concrete is within a field of view of the surface sensor, capturing surface profile data of a surface of the concrete during placement or finishing of the concrete, generating a surface profile depiction based on the surface profile data, displaying the surface profile depiction, and informing personnel regarding a variation in height based on the depiction. The concrete slab formed with this process may include a floor flatness value above 35 and a surface free of ground areas and free of filled areas.

A deflector for a screed assembly includes a front surface, a bottom surface, and a stepped transition connecting the front surface to the bottom surface.

A light-based measurement system is capable of directing a light beam to a cooperative target used in conjunction with a cable robot to accurately control the position of the end effector within a large volume working environment defined by a single coordinate system. By measuring the end effector while the device is in operation, the cable robot control system can be adjusted in real time to correct for errors that are introduced through the design of the robot itself providing accuracy in the tens or hundreds of micron range. A coordination processor runs control software that communicates with both the laser tracker and the cable robot. An action plan file is loaded by the software that defines the coordinate system of the working volume, the locations where actions need to be performed by the cable robot, and the actions to be taken.

The invention relates to a road paver or a feeder having a chassis driven by a drive unit, and a material hopper arranged in the working direction at the front of the road paver or the feeder, the material hopper having a hopper side wall extending in the working direction and a discharge flap tiltable about a pivot axis extending transversely to the working direction, the discharge flap comprising a flap base and a flap side wall which extends next to the hopper side wall and is fixed to the flap base and supported to be moveable relative to the hopper side wall, a protective cover, which at least partially engages around the edge of the flap side wall, being arranged on the hopper side wall.

An internal combustion engine to electric motor conversion system for a work machine is provided. The electric motor conversion system is sized to substantially conform to a footprint of the internal combustion engine on the work machine. The electric motor conversion system includes an electric motor, a power distribution unit and a connecting bracket. The electric motor is configured for direct mounting on a frame of the work machine. The power distribution unit is separate from and positioned atop the electric motor. The power distribution unit controls operation of the electric motor. The connecting bracket is separate from the electric motor and power distribution unit. The connecting bracket includes a base, first attachment elements extending from a lower surface of the base for attachment to the electric motor, and second attachment elements extending from an upper surface of the base for attachment to the power distribution unit.

Method for laying down a pavement consisting of paving material with a road paver screed in which a compaction unit pre-compacts the paving material at cyclical work cycles with a selectable stroke and at a selectable frequency while the pavement is laid down at a selectable paving speed and at least the stroke is automatically adjustable in response to paving parameters.

A remote controlled vibration imparting device for a concrete finishing tool uses a housing having a chamber surrounded by an inner surface of the housing. A vibrator with a support, a rotor with a shaft and weighted body, a motor, and a resilient link between the shaft and the motor is positioned within the housing chamber. The vibrator also includes a resilient band to separate the vibrator from the housing inner surface. First and second adaptors are employed for the housing to be placed between the handle and the terminus of a concrete finishing tool.
