DRIVE CONTROL SYSTEM FOR CONSTRUCTION MACHINERY
Disclosed is a drive control system for preventing a sudden slowdown of driving speed to reduce the shock felt by a driver, when compound-operating two-way driving and a work device in an excavator. The drive control system for the construction machinery of the present invention provides the drive control system for the construction machinery comprising: first and second hydraulic pumps; a left driving motor which connects to the first hydraulic pump and a hydraulic cylinder for a first work device; a right driving motor which connects to the second hydraulic pump and a hydraulic cylinder for a second work device; a driving speed selection device for selecting low or high driving speeds; a solenoid valve for transforming between low and high speeds; left and right driving spools for controlling the left and right driving motors according to the operation of the operation device; and a controller for outputting a high speed driving control signal to the solenoid valve for transforming between low and high speeds so as to convert the swivel angle of the sieve plates of the left and right driving motors by detecting simultaneous operation of two-way driving and the first and second work devices, when compound driving by operating two-way driving and the work devices while a low-speed driving mode is selected.
