Abstract
An operation control device is disclosed. According to a drive command value generated depending on the manipulated amount of a plurality of operating means (11, 12, 13, 14, 15, 16), the operation control device controls the drive amount of actuators (BMS, AMS, BKS, LDM, RDM, TNM) associated with the operated actuator. In the drive amount control, the operation control device changes a ratio of the manipulated amount and the drive amount command value by work accuracy flow rate data (41), weights the drive command values based on the same manipulated values of said operating means by priority mode weight data (42), and/or controls the timing of supply of the drive energy from at least two separate energy sources (FFP, RP) as a drive energy source for the respective actuators, and the supply amount of the drive energy, under control of pump utilization data (43) and pump swash plate control data (44). Every time the operating means are operated, these pieces of the control data are properly determined through proper operations (including the look-up table processing) according to the operations of the operating means, the selections of the work accuracy mode select switch (21) and t…
