ELECTRICALLY-OPERATED CONSTRUCTION MACHINE |
摘要 |
An electrically-operated construction machine with a battery charging operation. A lock switch provides a closed contact when a lock lever in a cab is placed in an unlock position. A feed port is disposed outside the cab to accept a cable from a commercial power source. The feed port is provided with a charge start switch . A control device has a motor control function for driving an electric motor with electrical power of a main battery when a signal is input from the lock switch. A charge control function is for charging the main battery with electrical power of the commercial power source when dictated by the charge start switch. The lock switch is wire-connected so as not to output the signal to the control device even if the closed contact is provided by the lock switch when the control device exercises charge control.
