摘要 |
To provide a work machine with high stability in which a dynamic balance can be evaluated easily while the influence of a sudden stop of an travel base, an upperstructure and a work front is taken into consideration. A stabilization control calculation unit (60a) and a command value generating unit (60i) are provided in a control device (60) of the work machine. The stabilization control calculation unit (60a) uses a sudden stop model and position information of each movable portion of the travel base and a machine body including the work front (6) to predict a change of stability until reaching a complete stop when a control lever (50) in an operating state is instantaneously brought back to a stop command position, and calculates a motion limit needed to prevent destabilization from occurring at any time instant until reaching the stop. The command value generating unit (60i) corrects the command information to a drive actuator on the basis of the calculation result of the stabilization control calculation unit (60a). |
