PROBLEM TO BE SOLVED: To provide an elongation state monitor which can set an outrigger jack in a suitable elongation state.SOLUTION: An elongation state monitor is equipped with an inclination angle measuring instrument 82 which measures an inclination angle θ of a vehicle body of a work vehicle CR, and a control unit 70 in which a measurement result θ measured by the inclination angle measuring instrument 82 is input. The control unit 70 determines that an outrigger jack 26 is in a proper elongation state when an amount of change in the inclination angle θ measured by the inclination angle measuring instrument 82 from a time before jack-up reaches a target variation Δα. Since it is determined that the outrigger jack is in a proper elongation state when an amount of change in the inclination angle θ of the vehicle body reaches the target variation Δα, the outrigger jack 26 can be set in a proper elongation state by stopping a telescopic motion of the outrigger jack 26 in the proper elongation state.SELECTED DRAWING: Figure 1
【課題】アウトリガジャッキを適正な伸長状態に設定できる伸長状態監視装置を提供する。【解決手段】作業車両CRの車体の傾斜角度θを測定する傾斜角度測定器82と、傾斜角度測定器82の測定結果θが入力される制御装置70とを備え、制御装置70は、傾斜角度測定器82で測定された傾斜角度θのジャッキアップ前からの変化量が目標変化量Δαに達したときに、アウトリガジャッキ26が適正伸長状態であると判断する。車体の傾斜角度θの変化量が目標変化量Δαに達したときに適正伸長状態と判断するので、その状態でアウトリガジャッキ26の伸縮動作を停止させることで、アウトリガジャッキ26を適正な伸長状態に設定できる。【選択図】図1
