Zusammenfassung:To provide a construction machine capable of detecting misalignment of connected front members constituting a front work machine.SOLUTION: A controller 20 calculates roll angles, which are tilt angles in the lateral direction of a vehicle body 2, with respect to the vehicle body 2 and a plurality of front members 4 to 6 based on the outputs of a plurality of posture detection devices 13 to 16. For each of the vehicle body 2 and the plurality of front members 4 to 6, the controller calculates a roll angle change amount, which is the difference between the roll angle detected at a first time and the roll angle detected at a second time different from the first time. The controller calculates determines whether there is a misalignment of connection in a front work machine 1 based on the respective roll angle change amounts of the vehicle body 2 and the plurality of front members 4 to 6.SELECTED DRAWING: Figure 3 【課題】フロント作業機を構成する複数のフロント部材の接続ずれを検出することが可能な建設機械を提供する。【解決手段】コントローラ20は、複数の姿勢検出装置13~16の出力を基に車体2および複数のフロント部材4~6のそれぞれの、車体2の左右方向の傾斜角であるロール角を算出し、車体2および複数のフロント部材4~6のそれぞれについて、第1時刻で検出されたロール角と前記第1時刻とは異なる第2時刻で検出されたロール角との差分であるロール角変化量を算出し、車体2および複数のフロント部材4~6の各ロール角変化量に基づいてフロント作業機1の接続ずれの有無を判定する。【選択図】 図3
