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.
