HYDRAULIC DRIVING DEVICE OF TRAVELING-TYPE WORKING MACHINE
To provide a hydraulic driving device capable of effectively utilizing a hydraulic fluid discharged from a hydraulic pump in a case when combined operation of only a traveling operation and a gripping operation, is performed.SOLUTION: A hydraulic driving device includes: a travel selector valve 39 capable of selecting a neutral position PN and a straight travel position PS; and a select control portion 51 performing a control to set the travel selector valve 39 to the neutral position in a single operation, performing a control to set the travel selector valve 39 to the straight travel position in performing a traveling/work arm combined operation in which a traveling operation and a work arm operation are simultaneously performed, and performing a traveling/gripping control as a control to set the travel selector valve 39 to the neutral position in an operation performing only the traveling operation and the gripping operation and in a traveling/gripping combined operation as an operation to move first and second travel bodies 11R, 11L while keeping a gripping portion at a gripping position.SELECTED DRAWING: Figure 3
【課題】走行操作と把持操作のみが行われる複合操作がなされる場合に油圧ポンプから吐出される作動油を有効に利用することが可能な油圧駆動装置を提供する。【解決手段】油圧駆動装置は、中立位置ＰＮと走行直進位置ＰＳとに切り換えられることが可能な走行切換弁３９と、単独操作がなされる時には走行切換弁３９を中立位置に設定する制御を行い、走行操作と作業腕操作が同時に行われる走行作業腕複合操作がなされる時には走行切換弁３９を走行直進位置に設定する制御を行い、走行操作と把持操作のみが行われる操作であって把持部を把持位置に保持しながら第１及び第２走行体１１Ｒ，１１Ｌを動かすための操作である走行把持複合操作がなされる時には走行切換弁３９を中立位置に設定する制御である走行把持制御を行う切換制御部５１と、を備える。【選択図】図３
