摘要: A hybrid construction machine is capable of performing satisfactory operations even when trouble occurs that disables the electric motor from outputting torque. The hybrid construction has both a hydraulic motor and an electric motor driving the swing structure and a controller for switching between a hydraulic/electric hybrid swing mode (using both the hydraulic motor and the electric motor) and a hydraulic-alone swing mode (using only the hydraulic motor). The switching is executed while achieving satisfactory operability and performance in each mode. Normally, an energy saving operation is performed in the hydraulic/electric hybrid swing mode. When the electric amount of an electricity storage device has gone out of a prescribed range or an abnormality has occurred in an electric system (e.g., failure of an inverter), the swing mode is switched to the hydraulic-alone swing mode so that driving with normal braking torque is possible by the hydraulic motor alone.

摘要: A hybrid construction machine has an electric motor for driving the swing structure, and the electric motor is prevented from becoming incapable of generating torque due to a low energy state or an overcharged state of an electricity storage device. A swing-mode selector switch 77 which is manually operated switches between a hydraulic/electric combined swing mode for driving the swing structure by driving both the electric motor and a hydraulic motor and a hydraulic solo swing mode for driving the swing structure by driving only the hydraulic motor. For a normal operation, the swing mode is initially set in the hydraulic/electric combined swing mode. For a specific operation, the operator switches the swing-mode selector switch from a hydraulic/electric combined swing position to a hydraulic solo swing position.

摘要: 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.

摘要: Disclosed is a hybrid construction machine that includes a control device and an auxiliary control device. The control device switches between a hydraulic/electric complex swing mode in which both the electric motor and the hydraulic motor are driven to drive the swing structure by using the sum of the torque of the electric motor and the torque of the hydraulic motor; and a hydraulic-only swing mode in which only the hydraulic motor is driven to drive the swing structure by using only the torque of the hydraulic motor. The auxiliary control device includes a monitoring controller that is connected to the control device and to the electric motor to monitor the temperature or electrical leakage in the electric motor as a substitute controller for the power control unit or the electrical storage device when the power control unit or the electrical storage device is removed due to a fault.
