<p>A controller of a hydraulic driving machine for controlling preferentially one working machine to other machines. The same operation quantity of a plurality of operation levers (3, 4) is weighted in accordance with the kind of works (M1 to M5), and the weight is stored in a memory of a controller in such a manner as to correspond to the kind of the operation levers (3, 4) and to the kind of the works. On the other hand, a switch (2) selects the kind of the works (M1 to M5). The operation levers (3 and 4) are operated, and when the switch (2) selects the kind of the works, the weight corresponding to the kind of the selected operation levers (3, 4) and the selected kind of the works (M1, M2) are read out from the memory, and the weight thus read out is added to the operation quantities (S1, S2) of the operated operation levers (3, 4). Then, signals (E, E') representing the operation quantities, to which the weight is added, but not the signals representing the operation quantities (S1, S2) of the operation levers (3, 4) themselves, are outputted to a control valve (7). The present invention can control one working machine more preferentially to other machines by merely adding an apparatus having a simple construction to an existing hydraulic circuit. Accordingly, the cost of the apparatus can be drastically reduced.</p> |
