  • Patent number: 10704209
    Abstract: A slipform paver comprises a machine frame carried by rolling assemblies, at least two of which being drivable and at least one being steerable, as well as comprising a support arranged on the machine frame for a slipform mould and a controller for controlling the rolling assemblies to adjust the velocities of the drivable rolling assemblies and the steering angles of the one or more steerable rolling assemblies. The controller is configured such that, when the steering angles of the one or more steerable rolling assemblies change, the velocities of the drivable rolling assemblies are adjusted so as to reduce the change in the velocity at which a reference point referring to the support for the slipform mould will move along a predefined trajectory, said change in velocity being caused by changing the steering angle. The quality of the concrete profile produced by the slipform paver is thereby improved.

  • Publication number: 20190212143
    Abstract: A civil engineering machine has a machine control unit configured to determine data which defines the position and/or orientation of a reference point on the civil engineering machine in relation to a reference system independent of the position and orientation of the civil engineering machine. A geometrical shape to be produced on the ground is preset in either a machine control unit or a field rover control unit. The field rover is used to determine a position of at least one identifiable point of the preset geometrical shape in the independent reference system. Curve data defining a desired curve in the independent reference system, corresponding to the preset shape, is determined at least partially on the basis of the position of the at least one identifiable point of the preset geometrical shape in the independent reference system.

  • Publication number: 20190204852
    Abstract: A construction machine system comprises a self-propelled construction machine and a total station. The construction machine possesses a machine frame, a drive means and a working means for altering the terrain. A position-determination means determines the position of a reference point on the machine in a first coordinate system independent of the machine. The position-determination means receives satellite signals from a global navigation satellite system (GNSS), wherein in normal operation the machine is controlled using the GNSS such that a reference point on the machine moves along a set target travel path. In a total station control mode, the machine is controlled without the GNSS and only using the total station based on a position of the standpoint and orientation of the total station ascertained in the GNSS control mode, and the position-determination of the construction machine occurs in a second coordinate system based on the total station.

  • Patent number: 10323629
    Abstract: A multi-stage piston compressor with a cooling arrangement is provided. The multi-stage piston compressor includes a compressor unit having a plurality of air-cooled cylinders on a crankcase housing, a motor unit that is mounted at an end face of the crankcase housing, and a cooler unit at an opposing end face of the compressor unit. An axial fan wheel of the cooler unit blows cooling air substantially outwards toward the compressor unit. In order to conduct cooling air externally in the region of said compressor unit, at least one air guide housing mounted between the cooler unit and the crankcase extends at least partially radially around the crankcase in a curved manner, such that the axial air flow generated by the axial fan wheel is at least partially guided around the crankcase in the radial direction and toward at least one cylinder at the air outlet side of the air guide housing.

  • Publication number: 20190145058
    Abstract: A self-propelled construction machine comprises a control unit configured in such a way that a point of reference on the construction machine moves along a route. A processing unit is configured in such a way that the position of at least one kink on the target route is determined from the imported data, at least a portion of the target route is displayed, and, for the section of the target route in which the target route has the kink, an interpolation curve that is substantially free of kinks is calculated. The relevant section of the target route is replaced by the interpolation curve for the determination of a modelled route. The control of the drive device is then not based upon the predetermined target route, but rather the modelled target route.

  • Patent number: 9896810
    Abstract: A self-propelled construction machine has an image capturing unit for capturing an image of the terrain, a display unit on which the captured image is displayed, and a data processing unit. In the displayed image, objects that are relevant to the building project, for example manhole covers, water inlets or curbs, are identified and a spatial data set containing information regarding the position of the identified objects in a reference system which is independent of the movement of the construction machine is determined from the image data of the capturing unit. The construction machine is then controlled in order to carry out translational and/or rotational movements on the terrain and/or to install a structure on the terrain or to alter the terrain on the basis of the spatial data set. As a result, the previously identified objects can be taken into account in the building project.
