| description | PROBLEM TO BE SOLVED: To provide a work vehicle equipped with a control portion which controls longitudinally and transversely inclined posture of a travelling machine body, which can prevent frames from contacting each other between the travelling machine body side and a crawler-type travelling device side.SOLUTION: The work vehicle comprises: a travelling machine body 2; a crawler-type travelling device 1; a pair of lifting/lowering actuator 48; a longitudinally inclination actuator 36; a lower-limit stopper 50 that restricts the travelling machine body 2 from descending below a predetermined position; lifting/lowering position detecting means 51; longitudinal inclination detecting means 49; and a control portion 60. The control portion 60 is configured to be capable of individually performing transversely-inclined posture control for retaining the travelling machine body 2 in a predetermined transversely-inclined posture and longitudinally and transversely-inclined posture control for retaining the travelling machine body 2 both in a predetermined transversely-inclined posture and in longitudinally-inclined posture. The control portion 60, when performing the longitudinally and transversely-inclined posture control, restricts the lifting/lowering actuator 48 from lowering the travelling machine body 2 so that a detected value by the lifting/lowering position detecting means 51 is higher than the lower-limit value.SELECTED DRAWING: Figure 10
【課題】走行機体の前後左右傾斜姿勢を制御する制御部を備えた作業車両において、走行機体側とクローラ式走行装置側との間で、フレーム同士が接触することを防止できる作業車両を提供することを課題とする。【解決手段】走行機体２と、クローラ式走行装置１と、一対の昇降アクチュエータ４８と、前後傾斜アクチュエータ３６と、走行機体２の所定位置以下への下降作動を規制する下限ストッパ５０と、昇降位置検出手段５１と、前後傾斜検出手段４９と、制御部６０とを備え、前記制御部６０は、走行機体２を所定の左右傾斜姿勢で保持する左右傾斜姿勢制御と、走行機体２を所定の左右傾斜姿勢及び前後傾斜姿勢で保持する前後左右傾斜姿勢制御とを各別に実行可能に構成され、該制御部６０は、上記前後左右傾斜姿勢制御の実行時には、昇降位置検出手段５１による検出値が上記下限値よりも高くなるように昇降アクチュエータ４８による走行機体２の下降を規制する。【選択図】図１０ |
