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.
