  "textContent": "Provided is an electrically-operated construction machine that is capable of increasing work efficiency in a battery charging operation. A lock switch 29 provides a closed contact when a lock lever 28 in a cab 6 is placed in an unlock position. A feed port 9 is disposed outside the cab 6 to accept a cable from a commercial power source 41. The feed port 9 is provided with a charge start switch 43 that is capable of dictating start of a control device 40 and exercise of charge control. The control device 40 has a motor control function and a charge control function, the motor control function for driving an electric motor 31 with electrical power of a main battery 7 when a signal is input from the lock switch 29, the charge control function for charging the main battery 7 with electrical power of the commercial power source 41 when dictated by the charge start switch 43. The lock switch 29 is wire-connected so as not to output the signal to the control device 40 even if the closed contact is provided by the lock switch 29 when the control device 40 exercises charge control.",
