Shovel and shovel control method
본 발명의 실시예에 관한 쇼벨은, 암폐쇄조작을 포함하는 암굴삭조작에 따라 굴삭을 행하는 쇼벨로서, 암굴삭조작이 행해진 것을 검출하는 굴삭조작 검출부(300)와, 쇼벨의 자세를 검출하는 자세 검출부(301)와, 쇼벨의 자세에 근거하여, 굴삭반력에 의하여 쇼벨이 끌려갈 때의 그 굴삭반력에 대응하는 암실린더(8)의 보텀측 유실(8B)의 압력을 제2 허용최대압력(P)으로서 산출하는 허용최대압력 산출부(302)와, 암굴삭조작이 행해질 때에, 제2 허용최대압력(P)을 넘지 않도록 암실린더(8)의 보텀측 유실(8B)의 압력을 제어하는 암실린더압 제어부(304)를 구비한다.
A shovel according to an embodiment of the present invention is a shovel that performs excavation in accordance with an arm excavation operation that includes an arm closing operation, and includes an excavation operation detection part (300) configured to detect that the arm 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 bottom-side oil chamber (8B) of an arm cylinder (8) corresponding to an excavation reaction force at a time when the shovel is dragged by the excavation reaction force as a second maximum allowable pressure (PAMAX), based on the position of the shovel, and a boom cylinder pressure control part (303) configured to control the pressure of the bottom-side oil chamber (8B) of the arm cylinder (8) not to exceed the second maximum allowable pressure (PAMAX) when the arm excavation operation is performed.
