Electrically Driven Construction Machine
An electrically driven construction machine is provided in which, in a case where a plurality of electrically driven construction machines operate simultaneously, it is possible to avoid exceeding the allowable electric power that can be output by the electric power receiving facility of a commercial electric power supply as an external electric power supply while distributing supplied electric power without a work imbalance between different machine bodies according to the respective demanded powers of the plurality of electrically driven construction machines thereby make it possible to perform work efficiently within an allowable electric power of the electric power receiving facility. To this end, a controller 53 computes an own demanded power Pd1 for driving the plurality of hydraulic actuators 13A, 19 on the basis of operation signals of the operation devices 35, 37, computes an allowable power as a power limit value usable by the electric motor 31 on the basis of the own demanded power, the demanded powers of the other electrically driven construction machines received through the communication device 46, and an allowable electric power of the electric power receiving facility 80 of the commercial electric power supply, and controls the electric motor 31 such that a power consumption of the electric motor 31 does not exceed the allowable power.
