Driving control device of excavator
The embodiment of the invention relates to a driving control device of an excavator. The riving control device of the excavator includes a first pump and a second pump connected to a diving motor of the excavator and supplying a working oil to a plurality of executors; a third pump supplying a working oil to a plurality of executors; a first driving control slide valve and a second driving control slide valve installed on the lateral flow paths of the upmost stream of the first pump and the second pump and controlling flowing of the working oil supplied to the driving motor; and a mode selection switch selecting a driving mode and a working mode and a driving confluence change-over valve. When the driving mode is selected by means of the mode selection switch, the working oil of the third pump is made to confluence to the upper stream sides of the first driving control slide valve and the second driving control slide valve.
