Abstract (en)

[origin: WO9713929A1] A control system for a construction machine, comprising a controller including a valve control (31), wherein in response to a command from a control member (30A, 30B) and to the output from a detector, the valve control (31) on the controller acts as a distributor to compare information (Qra, Qrb) on the demand of actuators (7A, 7B) specified by control members (30A, 30B) with the information on the flow from a working fluid supply, thereby determining optimum flow rates to the actuators (7A, 7B).
