<p><P>PROBLEM TO BE SOLVED: To secure the function of a vehicle body controller capable of responding when mounting a burglar-proof controller and also secure good workability when the burglar-proof controller is not mounted. <P>SOLUTION: The construction machine has a vehicle body including a running body and a working machine, an engine 1, a pump 2 driven by the engine 1, a hydraulic actuator operated by pressure oil discharged from the pump 2 and driving a vehicle body, and a vehicle body controller 13 which controls the number of rotations of the engine 1 and controls supply flow rate to the hydraulic actuator. The vehicle body controller 13 includes a flow rate limiting means for limiting the supply flow rate to the hydraulic actuator to a predetermined low flow rate. The vehicle body controller 13 includes a means for invalidating the operation of the flow rate limiting means and a selection means 50 having an effective selector switch 50a for outputting a selection signal for validating or invalidating the operation of the flow rate limiting means with respect to the vehicle body controller 13 and an invalid selector switch 50b. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
