Zusammenfassung:	To provide a hydraulic circuit travel operation device and a method capable of allowing a driver to intuitively perform a driving operation with comfort, even when a driver drives in a front/rear reverse state, and construction equipment using the same.SOLUTION: There is provided a hydraulic circuit travel operation device for operating driving of a forward direction and a rearward direction of a travel device which is provided on each of right and left sides of a vehicle body, from an operation device 5 on a driver seat through a hydraulic circuit, the hydraulic circuit can be switched between a normal circuit arrangement in which, a left side travel device is driven in a cross direction by a first hydraulic signal S1 and a third hydraulic signal S3, and a right side travel device is driven in a cross direction by a second hydraulic signal S2 and a fourth hydraulic signal S4, and a reverse circuit arrangement in which, the left side travel device is driven in the cross direction by the second and fourth hydraulic signals S2, S4, and the right side travel device is driven in the cross direction by the first and third hydraulic signals S1, S3.SELECTED DRAWING: Figure 2 【課題】運転者が前後反転して運転する場合であっても、直感的且つ快適に運転操作を行い得る油圧回路式走行操作装置及び操作方法、並びにこれを用いた建設機械を提供する。【解決手段】車体の左右に備えた走行装置の前進方向及び後進方向の駆動を、運転席に備えた操作装置５から油圧回路を介して操作する油圧回路式走行操作装置に関し、前記油圧回路は、左側走行装置が、第一の油圧信号Ｓ１と第三の油圧信号Ｓ３によって前後方向にそれぞれ駆動され、右側走行装置が、第二の油圧信号Ｓ２と第四の油圧信号Ｓ４によって前後方向にそれぞれ駆動される正位置の回路配置と、左側走行装置が、第二の油圧信号Ｓ２と第四の油圧信号Ｓ４によって前後方向にそれぞれ駆動され、右側走行装置が、第一の油圧信号Ｓ１と第三の油圧信号Ｓ３によって前後方向にそれぞれ駆動される逆位置の回路配置との間で切り換え可能に構成する。【選択図】図２
