摘要： In a hybrid construction machine, its display device displays, toward an operator, an artificial engine sound serving as load information according to a magnitude of a workload, instead of an engine sound. Furthermore, the display device issues an alarm sound to surrounding workers when performing an operation by only stored electrical power of an electrical energy storage device without using an engine. In this hybrid construction machine, in addition to the issuing of alarm from the display device during the operation without using the engine, the display device issues an advance notice sound for engine restart when at least one value out of the workload and a charge amount of the electrical energy storage device has become an advance notice set value close to a set value of engine restart.

摘要： An excavator has a controller capable of setting target torque of a rotation motor in accordance with a speed deviation between target speed set in accordance with an operation amount of an operating lever and actual rotation speed and is provided with an inverter for detecting necessary torque for rotating an upper rotating body, the necessary torque being changed in accordance with a working state of the upper rotating body. The controller calculates a correction amount which is increased as increasing the torque and subtracts the correction amount from the target speed so as to set new target speed. A controller sets first target torque for driving the motor and second target torque for maintaining the upper rotating body on the spot on the basis of the actual speed, and operates the motor in accordance with the torque which has a larger absolute value in the same direction as the first target torque among both the torque.

摘要： The present invention is to drive a hydraulic pump and a generator motor by an engine, to electrically charge a battery by a generator action of the generator motor, and to drive the generator motor by electric power of the battery so as to assist the engine. A governor position is changed by operations of a potentiometer for accelerator and a mode selection switch so as to control rotation speed of the engine. On the premise of the above configuration, generator output is limited by a controller at the time of accelerating the engine until the rotation speed of the engine reaches set speed determined on the basis of the operations of the potentiometer for accelerator and the mode selection switch, and hence engine load is reduced so as to assist acceleration.
