PROBLEM TO BE SOLVED: To easily change canopy specifications and cab specifications, by using a main part of a revolving frame of the canopy specifications and a main part of a revolving frame of the cab specifications in common. SOLUTION: This construction machine has a common frame 12 using the main part of the revolving frame 11 of the canopy specifications and the main part of the revolving frame 41 of the cab specifications in common. The revolving frame 11 of the canopy specifications is composed of a single body of this common frame 12, and the revolving frame 41 of the cab specifications is formed by installing a guard member 42 in the common frame 12. Thus, a specification change to a hydraulic excavator 31 of the cab specifications from a hydraulic excavator 1 of the canopy specifications, or a specification change to the hydraulic excavator 1 of the canopy specifications from the hydraulic excavator 31 of the cab specifications, can be quickly performed, and productivity can be enhanced.
