A paver, in particular a slipform paver, has a machine frame supported by front and rear undercarriages and a paving device for the paving of material. The paver is provided with an apron monitoring device for generating elevation profile data or elevation profile signals describing the elevation profile of the material deposited in the apron of the paving device in a direction transverse to the working direction. A data or signal processing device receives the elevation profile data or signals. The apron monitoring device provides the data needed to allow the material to be spread more evenly across the working width of the paver during the feeding operation by means of a spreading device for spreading the material to be paved in a direction transverse to the working direction and/or to allow the spreading device to be controlled for improved spreading of the material after the paver has been fed.

Paver having elevation profile monitoring equipment and methods for operation thereof

A self-propelled milling machine includes a controller which continuously locates an alterable position of a loading surface and of a slewable transport conveyor relative to a machine frame, or the position of the loading surface relative to the transport conveyor, and automatically controls one or more of the slewing angle, the elevation angle and the conveying speed of the transport conveyor, wherein discharged milling material impinges on pre-calculated points of impingement within the loading surface. The controller determines correction factors for the control parameter(s) as a function of a transverse inclination about the longitudinal central axis of the loading surface, a position angle between the longitudinal central axis of the loading surface and the longitudinal central axis of the transport conveyor or that of the machine frame, and/or the position of the pre-calculated point of impingement relative to an end of the loading surface lying on the longitudinal central axis.

Self-propelled milling machine, method for automatically loading a means of transport with milling material, as well as road or ground working unit

A device for working ground surfaces or roadways comprising a machine frame and a working drum in a drum housing arranged at said machine frame, where no less than one spraying device extending parallel to the working drum and featuring several outlet nozzles for spraying agents arranged next to one another and directed towards the working drum is arranged at the drum housing, where the outlet nozzles comprise one each drivable closing mechanism with a closing element which, in an open position, fully uncovers the nozzle channel of the outlet nozzle and, in a closed position, closes the nozzle channel. A controller drives the closing mechanisms, with the outlet nozzles and the related closing elements being adapted to one another in such a fashion that the flow cross-section in the outlet nozzle is variable in accordance with the position of the closing element on a specified path between the open position and closed position.

Device, as well as method for working ground surfaces or roadways

A device for working ground surfaces or roadways including a machine frame and a working drum in a drum housing arranged on said machine frame, where no less than one spraying device extending parallel to the working drum and featuring several outlet nozzles for spraying agents arranged next to one another and directed towards the working drum is arranged on the drum housing. Wherein each outlet nozzle includes a drivable closing mechanism with a closing element which, in an open position, fully uncovers the nozzle channel of the outlet nozzle. In a closed position, closes the nozzle channel. Such that the following functions are achieved: that a controller drives the closing mechanisms, with the outlet nozzles and the related closing elements being adapted to one another in such a fashion that the flow cross-section in the outlet nozzle is variable in accordance with the position of the closing element on a specified path between the open position and closed position.
