A control device for a wheeled hydraulic shovel controls the flow of hydraulic oil from a hydraulic cylinder that drives a work device, and performs control for a vibration suppression function that suppresses vibration of the hydraulic cylinder when the rotational speed of a wheel reaches a predetermined value or more. Furthermore, even if the vibration suppression instruction device instructs that the control of the vibration suppression function is enabled, the control of the vibration suppression function is disabled in a state in which the vehicle body is jacked up by the work device.
轮式液压挖掘机的控制装置控制来自驱动作业装置的液压缸的压力油的流动，执行在车轮的旋转速度达到预定以上时抑制液压缸的振动的振动抑制功能的控制。并且，即使在由振动抑制指示装置指示了振动抑制功能的控制的有效的情况下，在车身被作业装置顶起的状态下，也使振动抑制功能的控制无效。
