摘要： An object of the present invention is to provide a construction machine that can reduce particulate matter (PM) or nitrogen oxide (NOx) discharged from an internal combustion engine mounted on the construction machine. The construction machine 200 includes a diesel engine 101 controlled based on a torque command, an electric motor 102 mechanically connected to the diesel engine, an electric energy storage device 111 that supplies electric power to the electric motor, and a hydraulic pump 103. The construction machine performs work by driving the hydraulic pump using the diesel engine and the electric motor. A speed control device 118 controls a speed of the electric motor 102 based on a speed command. A torque limiter 115 obtains the torque command having a rate of change with time limited based on a torque target.

摘要： To rotate a rotary body at a constant velocity, a swing control device 50 of an electric rotary excavator controls the rotation of the rotary body with a small first torque command value T1. Thus, when inertia moment of the rotary body is changed due to extension or retraction of a boom and an arm, the change of the inertia moment affects the rotation velocity of the rotary body, and an operator can perform a rotation operation with the same feeling as in a hydraulically-driven excavator. In contrast, when operating a swing lever 10 for acceleration, the rotation is controlled with a large second torque command value T2. Accordingly, a good and quick operational feeling is obtained without a delay in acceleration or deceleration, and the degradation of workability can be avoided.

摘要： Limited operation of a vehicle for cargo handling, such as a forklift or a bulldozer, is allowed in the event of an emergency while theft of the vehicle is prevented even when the key is left in the vehicle. The vehicle is equipped with a storage unit for storing a password, a password input unit, a control unit for controlling selection of a normal operating mode with no restrictions on travel capability or cargo handling capability, an emergency operating mode where at least the travel capability of the vehicle is restricted, and a travel prohibited mode where neither the normal operating mode or the emergency operating mode is selected, and an emergency operating mode indicating unit. The control unit determines whether or not password entry is required when the vehicle is powered on and controls selection of the aforementioned normal operating mode when password entry is required or when a password entered and the password stored in the aforementioned memory unit match, the aforementioned emergency operating mode when emergency operation is indicated by the aforementioned emergency operating mode indicating unit, or the travel prohibited mode when neither the normal operating mode nor the emergency operating mode is selected within a predetermined specific amount of time or within a specific number of times of operation.
