Abstract

본 발명에 따른 건설기계의 유압제어장치는 유압펌프(11)(12); 각각이 상기 유압펌프(11)(12)로부터 토출되는 작동유의 흐름 방향을 제어하여 제 1 및 제 2 작업기 각각에 공급함과 아울러 상기 제 1 및 제 2 작업기 각각과 상기 유압펌프(11)(12)를 연결하는 유로 각각의 개도량을 제어하는 제 1 및 제 2 제어밸브유닛; 및 제 1 및 제 2 조작부 각각으로부터 입력되는 조작신호에 따라 상기 제 1 및 제 2 제어밸브유닛을 제어하는 제어부(70)를 포함하며, 상기 제어부(70)는 현재 작업모드가 일반작업모드인지 우선작업모드인지를 판단하고, 판단결과, 일반작업모드이면, 상기 제 1 조작부로부터 입력되는 조작신호에 따른 제 1 정상 유로 개도량을 산출하여 상기 제 1 제어밸브유닛에 출력하고, 상기 제 2 조작부로부터 입력되는 조작신호에 따라 제 2 정상 유로 개도량을 산출하여 상기 제 2 제어밸브유닛에 출력하며, 판단결과, 우선작업모드이면, 상기 제 1 작업기에 공급되는 작동유의 유량을 우선적으로 확보할 수 있도록 상기 제 2 제어밸브유닛의 개도량을 상기 제 1 정상 유로 개도량보다 작아지도록 상기 제 2 제어밸브유닛에 제어신호를 출력한다.
