  • Publication number: 20240084529
    Abstract: A system is provided for determining a volume of material milled, or a surface area milled, by a construction machine having a milling drum. The volume of material milled is determined as a function of a cross-sectional area of material to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling. The cross-sectional area is determined in part by direct machine observation of one or more profile characteristics of a ground surface in front of the milling drum. The surface area milled is determined as a function of the width of the area to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling.

  • Patent number: 11879216
    Abstract: 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.

  • Patent number: 11499899
    Abstract: The invention relates to a wear component of a milling machine, to a milling machine equipped with such a wear component, and to a method for determining the wear on a wear component. The wear component has associated with it at least one contactlessly readable electronic component for determining the wear on the wear component. Provision is made according to the present invention that at least one sensor is connected to at least one contactlessly readable electronic component for the transfer of data; that the contactlessly readable electronic component is embodied to receive measured data of the sensor and furnish them for contactless reading; and that at least one measurement portion of the sensor is guided, along at least one wear direction to be monitored, into a wear region or along the wear region of the wear component. The invention makes possible a better milling result as a result of optimized maintenance.
