<P>PROBLEM TO BE SOLVED: To provide a working machine that can effectively use the output torque of an engine. <P>SOLUTION: A reference displacement volume qc is calculated based on the information on the engine rated torque T and an average discharge pressure Pc. And an arithmetic operation to obtain a target displacement volume of pumps 101a, 101b is conducted, so that the displacement volume of a hydraulic pump supplying pressure oil to either one of right and left working fronts that requires pressure oil more than the other is greater than the calculated reference displacement volume qc, and the displacement volume of a hydraulic pump for the other working front is smaller than the calculated reference displacement volume qc. Thus, as the maximum flow rate for the working front requiring a higher flow rate can be preferentially increased, an engine output torque can be effectively used. <P>COPYRIGHT: (C)2012,JPO&INPIT |
