Abstract
A controller of a wheeled hydraulic excavator executes control of a vibration suppression function to control the flow of a hydraulic fluid from a hydraulic cylinder that drives a work implement, thereby suppressing vibration of the hydraulic cylinder when the rotation speed of wheels reaches a predetermined speed or higher. Furthermore, the controller disables the control of the vibration suppression function when the vehicle body is jacked up by the work implement, even when a vibration suppression instructing device has given an instruction for enabling the control of the vibration suppression function.
Claims6
A wheeled construction machine comprising:
- a travelable vehicle body equipped with a wheel;
- a work implement attached to the vehicle body;
- a controller that executes control of a vibration suppression function to control a flow of a hydraulic fluid from a hydraulic cylinder that drives the work implement, thereby suppressing vibration of the hydraulic cylinder when a rotation speed of the wheel reaches a predetermined speed or higher;
- and
- a vibration suppression instructing device that gives an instruction for enabling or disabling the control of the vibration suppression function by the controller, wherein
- the controller is configured to disable the control of the vibration suppression function when the vehicle body is jacked up by the work implement, even when the vibration suppression instructing device has given an instruction for enabling the control of the vibration suppression function.
