Abstract:
Disclosed are a construction machine such as an excavator having a hydraulic system and a method for controlling the construction machine. The construction machine includes: a hydraulic pump which is operated by a driving source to supply a working fluid; an actuator which operates by being supplied with the working fluid from the hydraulic pump; a spool which controls a flow of the working fluid supplied to the actuator from the hydraulic pump; an operating unit which controls an operation of the actuator; a memory unit which stores at least two operating speed profiles for the actuator; an operating speed selecting unit which selects any one of the at least two operating speed profiles stored in the memory unit; and a control unit which controls a discharge flow rate of the hydraulic pump based on the operating speed profile selected by the operating speed selecting unit.

Claim (Index 3):
The construction machine of  claim 1 , wherein the hydraulic pump is a variable capacity hydraulic pump which is capable of adjusting the discharge flow rate by changing an angle of a swash plate, the construction machine further includes: a regulator which is coupled to the swash plate to change the angle of the swash plate of the hydraulic pump; and a first electronic proportional pressure reducing valve which applies first pilot pressure to the regulator by a first control signal outputted from the control unit, and the control unit controls the discharge flow rate of the hydraulic pump by outputting the first control signal to the first electronic proportional pressure reducing valve.
