Shovel and shovel control method
본 발명의 실시예에 관한 쇼벨은, 암폐쇄조작 및 붐상승조작을 포함하는 복합굴삭조작에 따라 굴삭을 행하는 쇼벨로서, 복합굴삭조작이 행해진 것을 검출하는 굴삭조작 검출부(300)와, 쇼벨의 자세를 검출하는 자세 검출부(301)와, 쇼벨의 자세에 근거하여, 굴삭반력에 의하여 쇼벨이 부상할 때의 그 굴삭반력에 대응하는 붐실린더(7)의 로드측 유실(7R)의 압력을 제1 허용최대압력(P)으로서 산출하는 허용최대압력 산출부(302)와, 복합굴삭조작이 행해질 때에, 제1 허용최대압력(P)을 넘지 않도록 붐실린더(7)의 로드측 유실(7R)의 압력을 제어하는 붐실린더압 제어부(303)를 구비한다.
A shovel according to an embodiment of the present invention is a shovel that performs excavation in accordance with a complex excavation operation that includes an arm closing operation or a bucket closing operation and a boom raising operation, and includes an excavation operation detection part (300) configured to detect that the complex excavation operation has been performed, a position detection part (301) configured to detect a position of the shovel; a maximum allowable pressure calculation part (302) configured to calculate a pressure of a rod-side oil chamber (7R) of a boom cylinder (7) corresponding to an excavation reaction force at a time when the shovel is lifted by the excavation reaction force as a first maximum allowable pressure (P BMAX ), based on the position of the shovel, and a boom cylinder pressure control part (303) configured to control the pressure of the rod-side oil chamber (7R) of the boom cylinder (7) not to exceed the first maximum allowable pressure (P BMAX ) when the complex excavation operation is performed.
