Abstract: The present invention relates to a construction machine with automatic fan rotational speed regulation. The construction machine includes at least one electric motor that is connected functionally to a respective fan and a control unit formed for the purpose of registering operation-specific data. The control unit is configured for the purpose of regulating, depending on the operation-specific data, an electric output of the respective electric motor in order to adjust a desired target fan rotational speed on the fan.
Abstract: The present invention describes a construction machine with a drive unit and with a cooling system that comprises a fan. The fan is connected to the drive unit by means of a controllable viscous coupling, whereby the viscous coupling can be adjusted in such a way that a required fan rotational speed is set on the output side. The invention furthermore describes a method for the automatic fan rotational speed regulation for a cooling system in a construction machine.
Abstract: Road paver having a towing machine that is movable on a plane along a work area, and a screed provided to lay a road pavement, and having at least one measuring device configured to generate a point cloud that depicts a three-dimensional condition of the surface of the plane.
