Drive control device for rotary construction machine, and rotary construction machine provided with same
A drive control device (101) for a rotary construction machine (100) is provided with: a compensation control valve (33), which is interposed between a hydraulic pump (22) and a first actuator (7), and which can adjust the degree of opening so as to change the flow rate of hydraulic oil supplied from the hydraulic pump (22) to the first actuator (7); a swing operation device (42) to which a swing operation for operating the swing motor (11) is applied; a first operation device (41) to which a first operation for operating the first actuator (7) is applied; and a controller (70) that adjusts the opening degree of the compensation control valve (33) such that the actual turning acceleration is adjusted to a target turning acceleration corresponding to the amount of operation of the turning operation during a combined operation of the first operation and the turning operation.
回转式工程机械(100)的驱动控制装置(101)包括：补偿控制阀(33)，介于液压泵(22)与第1致动器(7)之间，能够调节开度，以使从液压泵(22)被供应至第1致动器(7)的工作油的流量变化；回转操作装置(42)，被施加使回转马达(11)工作的回转操作；第1操作装置(41)，被施加使第1致动器(7)工作的第1操作；以及控制器(70)，在第1操作与回转操作的复合操作时，调节补偿控制阀(33)的开度，以使实际的回转加速度被调节为与回转操作的操作量对应的目标回转加速度。
