Publication number: 20240084529Abstract: 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.Type: ApplicationFiled: September 28, 2023Publication date: March 14, 2024Inventors: Sven Paulsen, Stefan Wagner, Klaus Vollmann, Lothar Schwalbach, Cyrus Barimani

Patent number: 11879216Abstract: 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.Type: GrantFiled: February 15, 2023Date of Patent: January 23, 2024Inventors: Jens Brieskorn, Lothar Schwalbach, Stefan Wagner, Bernd Walterscheid, Gunnar Ramseger, Martin Dahm
