摘要

A working machine such as an excavator having an object for satisfying with the stored conditions required for respective work while minimizing and light-weighting condensers. As means to that end, there are provided a generator (18), an electrically-operated actuator (39) for generating power for operating a work member by electric power generated by the generator (18), ... Further, as means for charge-discharging electric power, there are provided a plurality of kinds of condensers (14A), (14B), and condensers used are selectively switched according to power required, work contents or the like.
