Main body of a construction machine

A construction vehicle includes a cooling device. The cooling device includes a radiator disposed on a vehicle body frame, an oil cooler disposed adjacent to the radiator with a rear surface side thereof being arranged to face in roughly parallel to a lower part of a front surface of the radiator, and an opening/closing mechanism including a rotary shaft. The rotary shaft is obliquely disposed with a top end portion thereof being arranged closer to the front surface of the radiator than a bottom end portion thereof is. The opening/closing mechanism is configured to pivot the oil cooler about the rotary shaft and simultaneously move the oil cooler with respect to the radiator. Either a counterweight mounted on a rear part of the vehicle body frame or a part of the vehicle body frame is disposed on a line horizontally extended from a bottom end portion of the oil cooler.
