PROBLEM TO BE SOLVED: To provide a revolving hydraulic work machine capable of driving an upper revolving body regardless of an inclined state.SOLUTION: A revolving hydraulic work machine comprises: a hydraulic pump 32; a revolving motor 36, which is connected to the hydraulic pump 32; a slewing control valve 42; a specific actuator 26, which is connected to the hydraulic pump 32; an actuator control valve 40, which is subject to an actuator operation; an actuator operating apparatus 50; revolving direction detectors 62A, 62B, which detect revolving direction of the upper revolving body; an inclination detector 64, which detects the inclination of the upper revolving body; and a control system. The control system comprises: base control parts 68, 70, which change opening of the actuator control valve 40 depending on the actuator operation; and an actuator flow limiting part 70, which further limits the actuator flow with the increase of an inclination angle when the rotation direction is hill-climbing direction.SELECTED DRAWING: Figure 2
【課題】傾斜状態にかかわらず上部旋回体の駆動が可能な旋回式油圧作業機械を提供する。【解決手段】旋回式油圧作業機械は、油圧ポンプ３２と、油圧ポンプ３２に接続される旋回モータ３６と、旋回制御弁４２と、油圧ポンプ３２に接続される特定アクチュエータ２６と、アクチュエータ操作を受けるアクチュエータ制御弁４０と、アクチュエータ操作器５０と、上部旋回体の旋回方向を検出する旋回方向検出部６２Ａ，６２Ｂと、上部旋回体の傾斜を検出する傾斜検出部６４と、制御系と、を備える。制御系は、アクチュエータ操作に応じてアクチュエータ制御弁４０の開度を変化させる基本制御部６８，７０と、旋回方向が登坂方向である場合に傾斜角が大きいほどアクチュエータ流量を制限するアクチュエータ流量制限部７０と、を有する。【選択図】図２
