ABSTRACT:
Cooling air is drawn in from only a lower opening formed in an upper rotating structure, and control valves for controlling hydraulic actuators are disposed in the flow path of the cooling air. A clearance is formed between an upright plate which is a part of a frame of the upper rotating structure and a side of a hydraulic oil tank which faces the central portion of the upper rotating structure. The clearance is located above the lower opening, so that the cooling air flows along the side face of the hydraulic oil tank. Fixed to the side face of the hydraulic oil tank is a valve stand, and control valves are attached to the valve stand. Thus, the construction is simple and the outside air can be readily drawn into the structure.
