PROBLEM TO BE SOLVED: To enhance the workability when performing a changing work, a cleaning work or the like of a heat exchanger. SOLUTION: A right engine unit 9 provided on a right side of a turning frame 5 comprises a base member 10 mounted on the turning frame 5, an engine assembly part 11 and a heat exchanger assembly part 17 which are mounted on the base member 10 in a dividing manner from each other. Similarly, a left engine unit provided on the left side of the turning frame 5 comprises a base member 25, an engine assembly part 26, and a heat exchanger assembly part 30. Thus, in the right engine unit 9, only the heat exchanger assembly part 17 can be singly detached while the engine assembly part 11 is left behind on the base member 10. In the left engine unit 24, only the heat exchanger assembly part 30 can be singly detached while the engine assembly part 26 is left behind on the base member 25. COPYRIGHT: (C)2009,JPO&INPIT
