Abstract: A controller of a driving device sets a target physical quantity relating to an orientation of a work device, calculates a current physical quantity relating to the actual orientation of the work device, calculates a physical quantity error between the target physical quantity and the current physical quantity, calculates an assistance operation value for assisting operation of an operator, corrects an operator operation value to an operator correction value so as to attain a small value when the physical quantity error is small as compared with when the physical quantity error is large, corrects the assistance operation value to an assistance correction value so as to attain a large value when the physical quantity error is small as compared with when the physical quantity error is large, and controls the orientation of the work device using a total value obtained by adding the operator correction value and the assistance correction value.

Abstract: A turn-drive apparatus capable of securing high acceleration at the time of turning start with a reduced relief loss includes a hydraulic pump of a variable capacity type, a turning motor, a turning control device, a relief valve, and a flow rate control device that controls a pump flow rate. The flow rate control device calculates a relief-cut-control target pump flow rate on the basis of the sum of a minimum relief flow rate and a turning-speed flow rate, and inputs a pump capacity command to the variable capacity-type hydraulic pump based thereon. The flow rate control device makes the relief-cut-control target pump flow rate larger than the sum of the minimum relief flow rate and the turning-speed flow rate at the time of turning start.
