Abstract
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. A controller computes an own demanded power Pd1 for driving the plurality of hydraulic actuators, on the basis of operation signals of the operation devices, computes an allowable power as a power limit value usable by the electric motor on the basis of the own demanded power, the demanded powers of the other electrically driven construction machines received through the communication device, and an allowable electric power of the electric power receiving facility of the commercial electric power supply, and controls the electric motor such that a power consumption of the electric motor does not exceed the allowable power.
