HYBRID CONSTRUCTION MACHINE WITH CONTROL OF SUPERSTRUCTURE BRAKING MEANS
Provided is a hybrid construction machine capable of letting the operator immediately stop the swing structure by performing a stopping operation for ordinary construction machines even when the swing structure moves differently from the operator's will for some reason. The hybrid construction machine comprises: an inverter controller which outputs a PWM signal to an inverter and thereby controls the revolution speed of an electric motor; a first electric circuit including blocking means which blocks the PWM signal outputted from the inverter controller to the inverter in response to either an immobilization selection inputted through a gate lock lever switch or an OFF selection inputted through an ignition switch; and a second electric circuit including a swing brake solenoid valve which activates a swing brake in response to either the immobilization selection inputted through the gate lock lever switch or the OFF selection inputted through the ignition switch.
