WORK MACHINE HYDRAULIC SYSTEM AND METHOD FOR CONTROLLING THE SAME
To reduce a leakage amount.SOLUTION: This work machine hydraulic system comprises: a boom cylinder 14 that raises or lowers a boom; a work tool cylinder 17 that operates a work tool fitted to the boom; a boom control valve 20A that controls the boom cylinder; a work tool control valve 20B that controls the work tool cylinder; a horizontal control valve 43 that can switch between a movement operation position for horizontally moving the work tool and a stop position for stopping the horizontal movement; and a control device 42 including a first information acquisition unit 111 that acquires permission or inhibition of the horizontal movement in the horizontal control valve; a second information acquisition unit 112 that acquires at least one of a raising operation and a movement of the boom; and a horizontal control unit 114 that switches the horizontal control valve to the stop position when the first information acquisition unit acquires the inhibition and the second information acquisition unit acquires one of the raising operation and the movement of the boom.SELECTED DRAWING: Figure 1
【課題】リーク量を低減することができるようにする。【解決手段】作業機の油圧システムは、ブームを上昇又は下降させるブームシリンダ１４と、ブームに装着された作業具を作動させる作業具シリンダ１７と、ブームシリンダを制御するブーム制御弁２０Ａと、作業具シリンダを制御する作業具制御弁２０Ｂと、作業具の水平動作を行う作動位置と、水平動作を停止する停止位置とに切り換え可能な水平制御弁４３と、水平制御弁における水平動作の許可又は不許可を取得する第１情報取得部１１１と、少なくともブームの上昇の操作及び動作のいずれかを取得する第２情報取得部１１２と、第１情報取得部が不許可を取得し且つ第２情報取得部がブームの上昇の操作及び動作のいずれかを取得した場合に水平制御弁を停止位置に切り換える水平制御部１１４と、を有している制御装置４２と、を備えている。【選択図】図１
