POSITION CONTROL APPARATUS AND METHOD FOR WORKING MACHINE OF CONSTRUCTION MACHINERY

摘要

A position control apparatus for a working machine of construction machinery according to the present invention comprises: a boom driving unit (21) for driving a boom (20); a bucket driving unit (31) for driving a bucket (30); a working machine actuator (40) for generating an actuating signal for driving the boom driving unit (21) and the bucket driving unit (31); a kick-down switch (50) for generating a kick-down signal for gear reduction; and a controller (80) for outputting a control signal to the boom driving unit (21) and the bucket driving unit (31) to move the boom (20) and the bucket (30) to a preset position, when a kick-down signal is generated by the kick-down switch (50), and an actuating signal is generated by the working machine actuator (40).
