Abstract (en)
It is made possible to perform power reduction control during non-operation of control levers, suppress a return to a normal power state when a control lever is accidentally moved, and make a smooth transition to an operation desired to be performed when a return is made to the normal power state. To this end, in a power reduction state, when a first cancellation condition in which two or more control levers are inclined simultaneously is satisfied or when a second cancellation condition in which one lever continues to be inclined is satisfied, a controller 50 determines that an operator "has an intention of canceling power reduction" and cancels power reduction control.
