    摘要： The purpose of the present invention is to provide a cooling fan control device for a construction machine, whereby the effects of heat caused by warm-up operation can be suppressed. This cooling fan control device is equipped with a control unit (10a) that controls the rotational speed of a cooling fan (21) in accordance with a main pump discharge pressure (P) detected by a main pump discharge pressure sensor (25), an engine cooling water temperature (Tw) detected by an engine cooling water temperature sensor (26), a hydraulic oil temperature (To) detected by a hydraulic oil temperature sensor (27), and an engine rotational speed (E) detected by an engine rotational speed sensor (28). The cooling fan (21) is rotated at the rotational speed controlled by the control unit (10a), thereby sending the generated cooling air to an oil cooler (19) and a control valve (13).
