HYDRAULIC TRAVEL DEVICE
PROBLEM TO BE SOLVED: To provide a hydraulic travel device capable of supplying a sufficient flow rate of working oil to hydraulic actuators other than a travel motor during traveling to drive the hydraulic actuators.SOLUTION: A hydraulic travel device includes: a second left travel control valve 75 configured to control supply of working oil supplied from a first hydraulic pump P1 to a left travel motor 16L; and left travel line selector valves 102, 103 configured to select working oil subjected to supply control by a first left travel control valve 61 or working oil subjected to supply control by the second travel control valve 75 to allow the working oil to be supplied to the left travel motor 16L.SELECTED DRAWING: Figure 3
【課題】走行中において走行モータ以外の他の油圧アクチュエータに十分な流量の作動油を供給して駆動させることができる油圧式走行装置を提供する。【解決手段】第１油圧ポンプＰ１から左走行モータ１６Ｌに供給される作動油の供給制御を行う第２左走行制御バルブ７５と、第１左走行制御バルブ６１により供給制御される作動油および第２左走行制御バルブ７５により供給制御される作動油のどちらを左走行モータ１６Ｌに供給可能な状態とするかを切り換える左走行ライン切換バルブ１０２，１０３とを備えて構成される。【選択図】図３
