Cooling device for construction machines

Abstract

The air conditioner capacitor is arranged at the front side of the oil cooler or the radiator against the flow of the cooling air, thereby carrying out maintenance of the oil cooler and/or the radiator at the rear side without removing the air conditioner capacitor arranged at the front side, thus improving maintenance. The turbocharger cooler 11 is structured to change the postures so as to swing up and down between the cooling posture in which the turbocharger cooler 11 is arranged in parallel with the radiator 8 and an open posture in which the turbocharger cooler 11 is arranged such that the front side of the radiator 8 is exposed. The air conditioner capacitor 10 and the oil cooler 9 are also structured to change the postures so as to swing horizontally between the cooling posture in which the air conditioner capacitor 10 and the oil cooler 9 are arranged in parallel with the radiator 8 and an open posture in which the air conditioner capacitor 10 and the oil cooler 9 are arranged such that the front side of the radiator 8 is exposed.
