    摘要： A road paver is provided with a drive, a bunker, a material conveying device, a screed comprising a tamping device and an electric heating device on the screed and/or on the tamping device, wherein a control unit is configured in such a manner that it determines, by means of a measurable electrical operating parameter of the electrical heating device on the screed and/or on the tamping device, the weight and/or the center of gravity and/or the width of the screed transversely to the working direction of the screed. A method for determining a width and/or a weight and/or a center of gravity of a screed of a road paver, comprising the steps: measuring an electrical variable of a heating device, in particular a heating power, a heating resistance or a power consumption of the heating device; calculating the weight and/or the center of gravity and/or the width of the screed transversely to the working direction of the screed by means of the electrical operating variable.

    摘要： The present invention relates to an attachment screed unit for a road paver, comprising a connecting screed, at least one adjusting screed which is adjustably mounted on the connecting screed and which is adjustable between a retracted position (P1) and an extended position (P2), as a result of which the paving width (b4) of the attachment screed unit can be set in a variable manner, and a hydraulic adjusting device, which is arranged in such a manner that it can adjust the at least one adjusting screed between the retracted position (P1) and the extended position (P2), the adjusting device comprising an electro-hydraulic unit which is arranged on the attachment screed unit (10), and the electric hydraulic unit comprising a separate hydraulic circuit with at least one hydraulic pump and an actuator. The present invention further relates to a road paver with such an attachment screed unit.

    摘要： A road finisher includes a screed plate extending at right angles to the working direction of the road finisher, a tamper bar disposed rearwardly and/or forwardly of the screed plate in the working direction, wherein at least one electrically operated heating element is configured to heat up a heating surface facing a road subsurface, the heating element comprising a heating layer at least partially obtained through thermal spraying onto a substrate surface, and a piston rod with connecting means to a tamper bar drive. The tamper bar is connected to the piston rod with an upper surface of the tamper bar contacting a lower surface of the piston rod, wherein the piston rod is single-pieced with regard to its connecting means and its lower surface, and the heating layer is located between the piston rod and the tamper bar, especially applied to the lower surface of the piston rod.

    摘要： The present invention relates to a method for controlling a construction machine which performs a working operation along a working trajectory on a ground depending on at least one operating parameter. A method according to the present invention comprises placing at least one mark, detectable by a sensor device, stationary on the ground in a region which, regarded from at least one position of the construction machine on the working trajectory, is located in the detection region of the sensor device. The mark is detected by the sensor device, resulting in the generation of sensor data which is processed by the data processing device of the construction machine. A control command is generated for the machine control of the construction machine for changing at least one operating parameter of the construction machine.
