HYDRAULIC DRIVING DEVICE
To provide a hydraulic driving device that can reduce energy loss when supplying/discharging hydraulic oil to/from a crushing cylinder.SOLUTION: A hydraulic circuit 5 comprises a crusher 9 including a first main cylinder 16A, a hydraulic pump 25, a control valve 23, a remote control valve 50 for receiving opening operation and closing operation of the crusher 9, a pressure sensor 29, a first switching valve 28, and a second switching valve 35. When the remote control valve 50 receives the opening operation or low-load closing operation, the first switching valve 28 switches to a position 28A, and the second switching valve 35 switches to a position 35A. When the remote control valve 50 receives high-load closing operation, the first switching valve 28 switches to a position 28B, and the second switching valve 35 switches to the position 35A. When no operation is performed, the second switching valve 35 switches to a position 35B.SELECTED DRAWING: Figure 5
【課題】破砕用シリンダに作動油を給排するときのエネルギ損失を低減することができる油圧駆動装置を提供する【解決手段】油圧回路5は、第1メインシリンダ16Aを含む破砕機9と、油圧ポンプ25と、コントロールバルブ23と、破砕機9の開き操作および閉じ操作を受けるリモコン弁50と、圧力センサ29と、第1切換弁28と、第2切換弁35と、を有する。リモコン弁50が開き操作または低負荷閉じ操作を受けると、第1切換弁28が位置28Aに切換り第2切換弁35が位置35Aに切換る。リモコン弁50が高負荷閉じ操作を受けると、第1切換弁28が位置28Bに切換り第2切換弁35が位置35Aに切換る。非操作時には、第2切換弁35が位置35Bに切換る。【選択図】図5
