WHEEL-TYPE WORKING MACHINE AND METHOD OF CONTROLLING THE SAME
A hydraulic excavator includes: an oil-pressure cut valve 41 for suspending pressure oil supply to a PPC valve; a lock switch for operating the oil-pressure valve 41; a control device 43 for controlling a switching of the oil-pressure cut valve 41. The control device 43 includes: a lock-state judging means 51 for judging a lock state by the lock switch; a traveling-state judging means 56 for judging a traveling state of the hydraulic excavator; an alert-issuing controlling means 57 for issuing an alert urging a locking of a working equipment; and a relay control means for actuating the oil-pressure cut valve 41 to suspend the pressure oil. The alert-issuing controlling means 57 issues the alert and the relay control means 52 actuates the oil pressure cut valve 41 when the hydraulic excavator 10 is judged to be traveling and the working equipment is judged to be not in the lock state.
