A boom cylinder (10) drives a boom (6) and has a head-side oil chamber (10h) and a bottom-side oil chamber (10b). The first valve (21) has a first opening (21c) for discharging oil in the head-side oil chamber (10h) to the oil tank (25), and supplies oil from the hydraulic pump (20) to the head-side oil chamber (10h). The second valve (22) has a second opening (22c) for discharging oil in the bottom-side oil chamber (10b) to the oil tank (25), and supplies oil from the hydraulic pump (20) to the bottom-side oil chamber (10b). The controller (30) individually controls the degree of opening (D1) of the first opening (21c) and the degree of opening (D2) of the second opening (22c) during work including operation of the boom (6).
动臂缸(10)驱动动臂(6)，具有头侧油室(10h)以及底侧油室(10b)。第一阀(21)具有将头侧油室(10h)的油向油罐(25)排出的第一开口部(21c)，且将来自液压泵(20)的油向头侧油室(10h)供给。第二阀(22)具有将底侧油室(10b)的油向油罐(25)排出的第二开口部(22c)，且将来自液压泵(20)的油向底侧油室(10b)供给。控制器(30)在包括动臂(6)的操作的作业时，对第一开口部(21c)的开口程度(D1)、以及第二开口部(22c)的开口程度(D2)单独地进行控制。
