Abstract
A working machine, such as an excavator, provided with a condenser, capable of satisfying condensing conditions required for various works, while minimizing the condensers and maintaining a light-weight. The working machine includes a generator and at a an electrically-operated actuator for generating power for operating a work member by electric power generated by the generator. Further, as for charging-discharging electric power, a plurality of kinds of condensers are provided, and the condensers used are selectively switched according to power required, work contents, or the like.
Claims8
