PROBLEM TO BE SOLVED: To mount a driving source without using a crane, and to ensure the stability of the driving source without installing an extra weight, by moving a self-propelled working apparatus driving source to a predetermined location of a frame arranged on a rear portion of a base machine via a climbing pedestal. SOLUTION: A frame 9 on which a working apparatus driving source 8 is mounted is arranged on a rear portion of an upper revolving body. The working apparatus driving source 8 is of a self-propelled type, constituted of a main body 8a in which a generator or a hydraulic unit is housed, and a crawler 8b is arranged below the main body 8a. When the working apparatus driving source 8 is mounted on the frame 9, a climbing pedestal 10 is set at one side of the frame 9, and the working apparatus driving source 8 is moved to a predetermined location of the frame 9 via the climbing pedestal 10. Thus, the working apparatus driving source can be mounted on the frame without using a crane. Further, by changing the mounting location of the working apparatus driving source, the stability of the driving source can be ensured without installing an extra weight, which dispenses with a bother of assembling a base machine.
