An auxiliary damping device of a construction machine comprises an auxiliary damping line, an auxiliary damping valve, a sensor, and a control pat. The auxiliary damping line supplies auxiliary damping oil to a front axle and a rear axle of the construction machine. The auxiliary damping valve is disposed on the auxiliary damping line to control the flow of the auxiliary damping oil. The sensor detects the stationary state of the construction machine. The control part controls operation of the auxiliary damping valve depending on whether the construction machine is stationary. Therefore, the auxiliary damping device can prevent unintended movement of a construction machine, particularly a wheel excavator, by excavating force during excavation work. |
