When an actuator in an operational mechanical system having a short continuous operation time is operated using a small-capacity electric motor (MG), an electric motor is rotated in the range exceeding a rated capacity, and during traveling with a long continuous operation time, the electric motor is rotated at the rated capacity or less. A controller (C) determines, from a signal provided from mode sensors (5a, 12a), whether the construction machine is in a traveling mode or in a traveling halt operation mode. When it is determined that the construction machine is in the traveling halt operation mode, the controller (C) sets the construction machine to a high output setting in which the electric motor (MG) rotates in the rage exceeding the rated capacity. When the construction machine is in the normal traveling mode, the controller (C) sets the construction machine to a low output setting so that the electric motor rotates at the rated capacity or less.
