CONSTRUCTION MACHINE

It is contrived to achieve both a control for limiting operation of a machine body and a control for raising engine speed when an obstacle is detected. To this end, a machine controller 13 performs operation limiting control by conducting a control for reducing the speed of the engine 19 when the ma...

description	It is contrived to achieve both a control for limiting operation of a machine body and a control for raising engine speed when an obstacle is detected. To this end, a machine controller 13 performs operation limiting control by conducting a control for reducing the speed of the engine 19 when the machine body does not require engine speed increase control and no obstacle is sensed by obstacle sensors 5 to 8, and the machine controller 13 performs supply flow rate reduction control for reducing the flow rates of the hydraulic fluid supplied to hydraulic actuators 3d to 3h from a hydraulic pump 21 when the machine body requires the engine speed increase control and an obstacle is sensed by the obstacle sensors 5 to 8.
