摘要： A control apparatus for a hydraulic excavator is capable of carrying out precise operations according to various kinds of classifications of works without requiring switching operations by an operator and management according to work records. The apparatus includes a classification of work discriminating section for recognizing a classification of work being carried out by the hydraulic excavator on the basis of data detected by sensors for detecting an operating amount of a lever for a boom and the like; sections for setting an operating mode of hydraulic pumps absorbing horse power and the like, according to the classification of work recognized; a hydraulic pump control section for controlling the hydraulic pumps according to the set operating mode; and an auto acceleration control section for making effective or invalid the auto acceleration control for controlling speed of an engine to a low speed when work stops. The apparatus further includes a device for readably storing the recognized classification of work in terms of a time series.
