ABSTRACT:
In a construction machine comprising an engine, hydraulic device, and heat exchanger for cooling the engine and the hydraulic device, which are all disposed in an upper rotating body of the construction machine, there is formed a maintenance passage along which maintenance portions of the engine and the hydraulic device are disposed so as to cross the upper rotating body. Exhaust air from cooling fans for sending air to the heat exchanger is discharged to the exterior of the machine body through the passage. Thus, the passage is utilized as an exhaust air passage for the heat exchanger, whereby it is possible to provide a construction machine improved in cooling efficiency for the heat exchanger.
